Terminal Attachment

The 3174 Establishment Controllers offer a wide variety of terminal attachments. They can be configured to connect terminals directly, via 3299 Terminal Multiplexers, via optional Terminal Multiplexer Adapters(#3103) and via optional Telephone Twisted Pair Terminal Multiplexer Adapters (#3105), or by a combination of these attachments.

The 3174 has an integrated four-port terminal adapter which permits up to four terminals to be directly attached, or by using one of the following, up to a maximum of 32 terminals can be attached:

  • One to four 3299 Terminal Multiplexers
  • One to four Terminal Multiplexer Adapter optional features (#3103)
  • Any combination of up to four 3299 Terminal Multiplexers and Terminal Multiplexer Adapter optional features.
  • One Telephone Twisted Pair Terminal Multiplexer Adapter (#3105)

The 3174 can be expanded to support up to sixty-four 3270 Category-A devices with the 3270 Port Expansion Feature hardware and Configuration Support-B Release 4 or later or Configuration Support-C. Sixty-four ports are attached by the following combination of terminal multiplexers for Models 21H, 21L, 21R, 22L, 22R (EMEA),23R, and 24R:

  • Any combination of up to two 32 port multiplexers (3299-032, 3299-32T, and feature #3105).

All models support attachment to an IBM 5209 Link Protocol Converter, which allows 3270 devices to be attached to a S/36, S/38, or AS/400 either locally or remotely (via the 5294 or 5394 Remote Control Unit) and concurrently to a S/370 host through a 3174.

All 3174 Models use the same terminal attachment interface architectures; they are the same as used by the 3274. Documentation describing the interface between 3X74 control units and their attached terminals is available.

The displays, printers, PS/2s, 3270-PCs, and IBM PCs (and associated emulation software) supported for attachment to the 3174 are listed below. Products and software not specifically listed should be tested by the customer to verify correct operation. Continued improvements in the 3174 and attaching terminals may require Licensed Internal Code or hardware updates to the attaching products. Refer to RETAIN for information on product compatibility.

Either RG-62A/U coaxial cable, IBM Cabling System media or specified telephone twisted-pair wire (IBM Cabling System Type 3 media) can be used for connections to the 3174. Depending on the type of wire used, the distance between the 3174 and its attached terminals can be up to 1,500m (4,920 ft); when a 3299 is used, the maximum distance can be up to 3,000m (9,840 ft). The 3174 ports have Dual Purpose Connectors (DPC), which do not require a BALUNs to connect IBM Cabling System Types 1, 2, or 9 media, however some terminals may require a BALUN for IBM Cabling System attachment. (Refer to the appropriate terminal pages.) Using a BALUN reduces the maximum allowable wire lengths as shown below.

Technical Description

Physical Specifications

Notes:

  1. These dimensions are minimum requirements for functional operation of the machine. These dimensions allow sufficient airflow to provide cooling.
  2. If the unit is installed with minimum clearance, service access must be provided.
  3. Models 21L through 24R are usually mounted on a rail in a standard 483-mm (19-in.) rack (IBM type 9309 or an equivalent). Models 21L through 24R require 6 EIA units of space within the rack.
  4. Because of the weight of the Models 21L through 23R, along with the added weight of the cables attached to them, IBM requires that these models be mounted on horizontal rails or a shelf when mounting them in a rack. DO NOT use cantilever mounting.

Electronic Customer Support

HONE

Use the HONE configurator (CFSYSTEM) to assist in configuring the 3174 before entering an order.

Performance Information

There are two 3174 performance aids on HONE. One is a document with tables for a wide variety of environments. To access this, do the following from the HONE main menu:

  1. Select Technical Support (4).
  2. Select Techbulletin (6).
  3. Search on CAG7.

This gives you the 3174 performance guide document, which is in several files.

The second is a simulation model, FIVE3174. This has the potential to reproduce a particular situation but requires work to set up inputs and to interpret results. To get to FIVE3174, just enter its name on the command line of the HONE main menu. The model does have extensive help and an interactive front-end to help build the required inputs.

Licensed Internal Code (LIC) Management

To aid a user in controlling 3174 customization and LIC changes in their 3174 network, several 3174 network management specify codes are provided. These 3174 specify codes allow the identification of a 3174 as the Central Site management location and provide a means to block automatic 3174 LIC shipments and prevent customization at user designated 3174s, allowing the user to better manage changes in the 3174 network. Users that do not specify any LIC management specify codes will continue to receive the normal notifications for LIC EC updates. Via these notifications, the user can indicate what actions are appropriate for each EC update.

Inhibit LIC Shipment (#9005)

Models 21L, 21H, 21R, 22L, 22R (EMEA), 23R, and 24R

This specify code blocks shipment of Licensed Internal Code diskettes (Control and Full Function Utility) and related documentation to the 3174 location. When this specify code is ordered, a Limited Function Diskette is initially shipped with a 3174 providing diagnostic and utility capabilities, but does not allow customizing or revision of a 3174 configuration. After initial shipment, the user must distribute any update of this Utility/Diagnostic code from their central site management location to allow proper diagnostic capability at the managed 3174 location. This specify feature is a PLANT ONLY feature. After initial shipment, a "Records Purpose Only" (RPO) MES may be processed to add or remove this feature to/from the machine history.

Central Site Distribution Aid (#9008)

Models 21H, 21L, 21R, 22R (EMEA), 23R, and 24R

When the Model 21H, 21L, 21R is the Central Site 3174, only Configuration Support-B Release 2 and future releases apply.

When the Model 23R is the Central Site 3174, only Configuration Support-B Release 4 and future releases apply. When the Model 14R, 24R, and 64R is the Central Site 3174, only Configuration Support-C Release 4 and future releases apply. Therefore, all the 3174s in the distribution network must operate at lease the configuration support level of the Central Site 3174. It enables a Central Site customer to order the Licensed Internal Code, RPQs, and Downstream Load Device Code for the central site 3174. One set of code ordered through AAS is shipped to the 3174 with #9008. This specify code cannot be ordered on 3174s that have the Inhibit LIC Shipment specify code (#9005). This specify code also provides automatic shipment of LIC update ECs from IBM. This specify feature is a PLANT ONLY feature. After initial 3174 shipment, a "Records Purpose Only" MES may be processed to add or remove this feature to/from the machine history.

Central Site Distribution Aid (#9009)

Model 22L

This specify code identifies the Model 22L as the Central Site 3174. When the Model 22L is the Central Site 3174, only Configuration Support-B Release 3 or later releases apply. Therefore, all the 3174s in the distribution network must operate at Configuration Support-B Release 3 or beyond. It enables a Central Site customer to order the Licensed Internal Code, RPQs, and Downstream Load Device Code for the central site 3174. One set of code ordered through AAS is shipped to the 3174 with #9009. This specify code also provides automatic shipment of LIC update ECs from IBM. This specify code cannot be ordered on 3174s that have the Inhibit LIC Shipment specify code (#9005). This specify feature is a PLANT ONLY feature. After initial shipment, a "Records Purpose Only" MES may be processed to add or remove this feature to/from the machine history.

Configuration Support-B License for Configuration Support-C (#9011)

Models 21L, 21R, 22L, 22R (EMEA), 23R, 24R

This specify code will provide the Configuration Support-C licensed 3174s the ability to receive a Configuration Support-B license free of charge. Configuration Support-C (F/C #6010, #6060) or the 3174 Value Package (F/C #4730, #4710) is required to order #9011. Configuration Support-B diskettes and publications are shipped. Specify code #9005 can be used in conjunction with S/C #9011 to block the shipment of the LIC diskettes and publications. Specify code #9006, #9008, or #9009 can used in conjunction with #9011 for a Central Site 3174.

Configuration Support-N Diskette Shipment (#9014)

Not applicable to 3174 Models 90R, 91R, 92R, and 95R. This specify code is provided to enable the Central Site customer to order the Configuration Support-N diskette for the Central Site machine.

Communication Adapters

Asynchronous Emulation Adapter (#3020)

Models 21L, 21H, 21R, 22L, 22R (EMEA), 23R, 24R

The AEA adapter card provides 8 asynchronous serial communication ports. An asynchronous ASCII device or host may be attached to each of the 8 ports using direct connection, or a communication link (switched or nonswitched) facility. The AEA asynchronous functions provided are:

  • ASCII Terminal Emulation: Select 3270 displays can emulate a 3101 or DEC VT100 display, and 3270 Printers can emulate an ASCII printer for connection to a ASCII host(s) or public data network.
  • 3270 Terminal Emulation: ASCII displays can emulate a 3178 Model C2 or 3279 Model 2A (4-color display), and ASCII printers can emulate a 3287 Model 2 for connection to an IBM host.
  • ASCII Pass-Through: ASCII displays and printers can connect to ASCII hosts and public data networks through the adapter.

This feature code provides an AEA adapter with a microprocessor, storage and control logic, an I/O panel with eight EIA 232-D 25 pin connectors and a diskette containing the AEA Licensed Internal Code for the AEA adapters. For the Model 21H, 21L, 21R, 22L, 22R (EMEA), 23R, and 24R, this feature code includes an AEA adapter with a microprocessor, storage, control logic, and eight EIA-232D 15 pin connectors and a diskette containing the AEA Licensed Internal Code for the AEA adapter. A 15-pin to 25-pin conversion cable (IBM P/N 39F7864 or customer provided) is required to bridge between the new 15-pin connectors and each existing 25-pin RS-232 customer provided cable when revising previously installed 25-pin RS-232 cables. (When AEA Licensed Internal Code is required at a Central Site 3174 for central site 3174 network management, and the Central Site 3174 does not have FC (#3020), 3174 specify code (#9015) should be used.)

As a convenience to our customers, with Release 5 and future releases of Configuration Support-C, you will no longer receive a separate diskette and have to do a DSL merge of a feature diskette. The AEA Licensed Internal Code has been premerged onto the Control Extension Diskette.

Maximum: Three AEA adapters.

Prerequisites/Corequisites: (1) A second diskette drive or 20 MB Fixed Disk optional feature. (2) Licensed Internal Code DSL Diskette released in conjunction with this feature. (3) A user provided, appropriately wired, cable from the AEA port to an ASCII device or DCE is required. (4) Requires Configuration Support-B, Release 2 or later or Configuration Support-C. Limitations: (1) When non-SNA protocols are used to communicate with an IBM host, the maximum number of terminals supported for concurrent communications to the primary host is 32. This limitation includes both IBM 3270 terminals and ASCII terminals emulating 3270 terminals. (2) The adapter for Models 11L, 11R, 12L, 12R, 13R, 14R, 61R, 62R, 63R, and 64R will not operate in Models 21H, 21L, 21R, 22L, 22R (EMEA), 23R, and 24R. (3) The adapter for Models 21H, 21L, 21R, 22L, 22R (EMEA), 23R, and 24R will not operate in Models 11L, 11R, 12L, 12R, 13R, 14R, 61R, 62R, 63R, and 64R.

Performance Considerations: Response times when this feature is used, will depend on many variables including the number and type of terminals attached, the transaction rates and contents, and system parameters such as RU lengths, pacing, etc. The 3174 Performance Guideline on HONE includes Asynchronous Emulation Adapter performance information.

This feature may be used for two different functions: (1) Alternate IML Configuration; (2) IBM 16/4M Bps Token-Ring Gateway when using Configuration Support-B or Configuration Support-C.

(1) When used for the Alternate IML function, this feature and the appropriately configured Licensed Internal Code, allows the 3174 Models 11L, 11R, 12L, 12R, 14R, 21H, 21L, 21R, 22R (EMEA), 22L, 24R to operate in an alternate configuration on an IBM Token-Ring as a Model 23R. Licensed Internal Code customization and host definition for operation with this feature are the same as a Model 23R.

(2) When used for the IBM 16/4M Bps Token-Ring Gateway function, this feature with Configuration Support-B, Releases 1 or 2, provides for data passage between a single IBM host and 16/4 Mbps Token-Ring Network. This feature with Configuration Support-B, Release 3 or later or Configuration Support-C and a model 22L (with ESCON Director) or a model 21H, 21L, or 21R with Concurrent Communication Adapter(s) provides for data passage between multiple IBM hosts and a 16/4 Mbps Token-Ring Network.

With the Multihost Token-Ring Gateway support announced in Configuration Support-B, Release 3, a Token Ring device can connect to host(s) on the 3174's primary link and/or connect to SNA/SDLC host(s) via the Concurrent Communication Adapter(s). The same functions supported by the IBM 16/4 Mbps Token-Ring Gateway optional Token-Ring feature (#3026) are supported by this feature when used as a Token-Ring Gateway. See optional Feature (#3026) for further details.

Maximum: One. Corequisite: Configuration Support-A Release 5 (Alternate IML only), Configuration Support-B or Configuration Support-C. Limitations: (1) If this adapter is used for an alternate host attachment, the management and transmission of Licensed Internal Code for the alternate host attachment configuration via Central Site Change Management is not supported. (2) Concurrent channel or teleprocessing operation and Token-Ring operation is supported with Configuration Support-B Release 2 or later or Configuration Support-C. (3) Concurrent channel or teleprocessing operation and Ethernet operation is supported with Configuration Support-C Release 4. (4) Cannot be installed on a 3174 with an optional Token-Ring gateway feature (#3026). (5) SNA/X.25 protocol is not supported when used as a Token-Ring Gateway. (6) The Ethernet Adapter (feature 3045 or base host link for Model 24R) and the Type 3A Dual Speed 16/4 Adapter cannot be operational in the same 3174 at the same time. Both adapters may be installed in the 3174 at IML time, but only one can be configured as the active host link or gateway.

Ethernet Adapter (#3045)

The Ethernet Adapter has a RJ-45 connector for attachment to the 10BaseT network. The cable to attach to the 10BaseT network is customer provided.

The Ethernet Adapter and properly configured Configuration Support-C Release 4.0 Licensed Internal Code may be used for three different functions: (1) Alternate IML Configuration; (2) SNA Gateway; (3) Additional TCP/IP host access.

Note: Configuration Support-C Release 4 or higher is required for 3174s with Ethernet capability (i.e., feature code 3045 is installed or the 3174 is a model 14R, 24R or 64R).

(1) When used for the Alternate IML function, 3174 Models 11L, 11R, 12L, 12R, 13R, 21H, 21L, 21R, 22L, 22R (EMEA only), 23R, 61R, 62R, or 63R can operate in a alternate configuration as a Model 24R. Dependent 3270 CUT and ASCII terminals can access multiple hosts (TCP/IP Telnet, TCP/IP Telnet TN3270, 3270 SNA) via the Ethernet LAN.

(2) When used for the SNA Gateway, SNA traffic is passed between local and remote SNA hosts and Ethernet LAN attached terminals (e.g., 3174 DSPU attached workstations and intelligent workstations). A PU to PU session is made between the SNA host and the Ethernet LAN attached terminal. Dependent 3270 CUT and ASCII terminals attached to the SNA Gateway can access both upstream SNA hosts and Ethernet LAN attached TCP/IP Telnet hosts.

(3) When used for the additional TCP/IP host access, dependent 3270 CUT and ASCII terminals can access SNA hosts via upstream local or remote host links and TCP/IP Telnet hosts via the downstream Ethernet LAN.

Maximum: One Ethernet Adapter per 3174.

Prerequisite: (1) The 3174 must have Configuration Support-C Licensed Internal Code (F/C 6010, 6015, 6060, or 6065); a second 2.4MB Diskette Drive (F/C 1048) or a 20MB Fixed Disk Drive (F/C 1056); at least 3MB of Control Storage (F/C 1012, 1014, or 1016). The 3174 Value Package (F/C 4710) provides all the prerequisites. (2) The 3174 must have one open feature slot (slots 11-15).

Limitations: (1) The Ethernet Adapter and the Type 3A Dual Speed (16/4) Adapter cannot operational in the same 3174 at the same time. Both adapters may be installed in the 3174 at IML time, but only one can be configured as the active host link or gateway. (2) Only one Ethernet Adapter can be installed in a 3174. (3) With the Ethernet Adapter installed, coax attached intelligent workstations can communicate in a peer mode with other intelligent workstations coax attached to the same 3174 only. There is no bridging support between 3174 attached intelligent workstations and the Ethernet LAN.

Adapters for Models 21H, 21L, 21R, 22L, 22R (EMEA), 23R, and 24R will operate in Models 11L, 11R, 12L, 12R, 13R, and 14R.

Telephone Twisted-pair Terminal Multiplexer Adapter (#3105)

Models 21H, 21L, 21R, 22L, 22R (EMEA), 23R, and 24R

The Telephone Twisted-pair Terminal Multiplexer Adapter (TTP TMA) is a new 3174 adapter that allows attachment of up to thirty-two 3270 category-A devices to the 3174 Establishment Controller via 25-pair (50-wire) telephone twisted-pair (TTP) cable, that meets the specifications for IBM cabling system type 3 media. The TTP TMA has three connectors (one dual purpose connector - DPC and two 50 position female "telco" connectors). The DPC Connector is attached to port 0 of the 3174 terminal adapter or port expansion feature (FC 3100) via a short piece of coax. The two 50 position female "telco" connectors are then connected to the customer's TTP wiring facilities by two 25-pair TTP cables. Each cable transports the data streams for up to sixteen terminals with sixteen wire pairs. Nine of the wire pairs in the cable are unused.

The customer is responsible for providing the 25-pair cables. The 50 position female connectors on the TTP TMA card are referred to as "telco" commonly used for normal telephone wiring connections. A dual purpose connector to twisted pair (DPC-T3) adapter - p/n 83X9758 (or equivalent) is required for circuit termination at the terminal. Proper ring and tip polarity must be maintained. Prerequisites: Configuration Support-A Release 5.4, Configuration Support-B Release 4, or Configuration Support-C Licensed Internal Code (LIC). Limitations:

  1. Telephone wiring must meet the specifications for IBM cabling system (ICS) type 3 media. Refer to 3174 Establishment Controller Site Planning (GA23-0213) for type 3 media specifications.
  2. The maximum supported distance between the TTP TMA and a device is 900 feet (275 meters). There is no minimum distance.
  3. The TTP TMA Adapter requires one feature slot.
CSU: Yes. Setup instructions are supplied.

Licensed Internal Code (LIC) Features

Licensed Internal Code Description

The 3174 is supported by multiple configuration support packages and releases of Licensed Internal Code. Selection of the appropriate LIC configuration depends on the desired 3174 functions.

Configuration Support-B is an optional Licensed Internal Code feature that is available for all 3174 models, however certain 3174 models require specific Configuration Support-B releases. Models 21H, 21L, and 21R require Configuration Support-B Release 2 or later or Configuration Support-C. Model 22L requires Configuration Support-B, Release 3, or later, or Configuration Support-C. The 3174 Model 23R requires Configuration Support-B, Release 4, or Configuration Support-C.

Configuration Support-C is an enhanced function optional Licensed Internal Code feature that is available on 3174 Models 21H, 21L, 21R, 22L, 22R (EMEA), 23R, and 24R. The 3174 Model 22R requires Configuration Support-C Release 1.1 or later. The 3174 Model 24R requires Configuration Support-C Release 4.0.

Configuration Support-B (#5010)

Models 21H, 21L, 21R, 22L, 22R, 23R, 24R

This feature provides the latest release of Configuration Support-B Licensed Internal Code.

Prerequisites: Requires either a 2.4MB diskette drive or 20MB hardfile, and a minimum of 2MB control storage. For further details, see Configuration Support-B in the Licensed Internal Code section.

Configuration Support-C (#6010, #6015)

Models 21H, 21L, 21R, 22L, 22R, 23R, 24R

This feature provides the latest release of Configuration Support-C Licensed Internal Code. Configuration Support-C is required to support downstream ISDN connected PU T2.0 devices. Configuration Support-C is a prerequisite for the APPN feature as well as the Peer Communication feature. Configuration Support-C is a prerequisite for Ethernet Support (feature 3045 and 3174 Models 14R, 24R, and 64R). Configuration Support-C is also a prerequisite for Frame Relay Communications Support (feature 7020/7070).

Optional feature #6010 should be ordered if the 3174 does not have Configuration Support-B installed.

Optional feature #6015 provides an upgrade option for 3174s that already have Configuration Support-B installed.

As a convenience to our customers, with Release 6 and future releases of Configuration Support-C, you no longer can order the following features as they are now part of Release 6. They have been premerged onto the Control Extension Diskette.

Advanced Peer-to-Peer Network (APPN)
Peer Communication
ASCII Emulation Adapter Diskette Feature #9015/3020


Prerequisites: (1) Requires at least 3MB of control storage. (2) Requires either two 2.4MB diskette drives or one 2.4MB diskette drive and one 20MB Fixed Disk Drive.

APPN Feature

Models 21H, 21L, 21R, 22L, 22R (EMEA), 23R, 24R

Provides Advanced Peer-to-Peer Networking (APPN) Network Node services to support the low-entry networking (LEN) end node, APPN end node (EN), and APPN support for dependent LUs locally attached to the 3174. The 3174 NN fully participates in an APPN Network by maintaining directory and topology data bases that are used to respond to requests from APPN nodes, calculate the best route based on class of service, and transport the session data reliably based on transmission priority.

As a convenience to our customers, with Release 5 and future releases of Configuration Support-C, you will no longer receive a separate diskette and have to do a DSL merge of a feature diskette. The APPN Licensed Internal Code has been premerged onto the Control Extension Diskette.

Prerequisites/Corequisites: Requires Configuration Support-C (#6010, #6015, #4710,#4730,#4740)

Peer Communication

Models 21H, 21L, 21R, 22L, 22R (EMEA), 23R, 24R

The 3174 PEER Communication feature provides a LAN segment for Intelligent Workstation (IWS) connected to an IBM 3174 Establishment Controller with a 3270 coax connection card. In addition to providing a LAN environment for IWSs, the 3174 also acts as a Source Routing Bridge between these IWSs and a real Token-Ring LAN connected to the 3174. Participating IWSs can communicate with each other or to any other IWS or LAN server that is connected to the Token-Ring. Peer Communication operates over existing 3270 wiring, saving the expense and disruption or recabling to Token-Ring wiring or adding Token-Ring adapters to IWSs which have 3270 connection cards. Support for Ethernet connections are not available.

Peer Communication provides Token-Ring access for DOS 3.3, 4.0, 5.0; as well as IBM Extended Services for OS/2 or IBM OS/2 LAN Server and Requester.

Novell's NetWare can be used on DOS Workstations using the LAN Support Program Network Driver. For best performance, use NetWare Workstation update for DOS/Windows with burst mode. This program operates at the 802.2 interface level, not the IPX or NetBIOS level.

For 3174 LIC Configuration Support C Release 1 or later, optional feature #8010 (Peer Communication) should be ordered.

For 3174 LIC Configuration Support B Release 3 or 4, RPQ 8Q0718 is required.

As a convenience to our customers, with Release 5 and future releases of Configuration Support-C, you will no longer receive a separate diskette and have to do a DSL merge of a feature diskette. The Peer Communications Licensed Internal Code has been premerged onto the Control Extension Diskette.

Prerequisites/Corequisites: Requires Configuration Support-C LIC (#6010, #6015, #6060, #6065). A Token-Ring Adapter (#3026, #3044, #3031, or #3030) is required when intelligent workstations attached to the 3174 must communicate with workstations attached to the Token-Ring LAN. 3174 Models 13R, 23R, and 63R are shipped with a Type 3A Token-Ring Adapter as part of the base model.

Frame Relay Communications (#7020))

Models 21R, 23R, 24R

The 3174 Frame Relay Communications feature supports RFC 1490 for multiplexing multiple protocols over a single Permanent Virtual Circuit (PVC). The 3174 can communicate with any product, IBM or OEM, that supports RFC 1490.

The protocols supported are: SNA (3270), LAN Gateway, TCP/IP, and APPN. The 3174 can support up to 250 Data Link Connection Identifiers (DLCI) with a single access to a private or public frame relay network. The support adheres to the existing standards for Permanent Virtual Connections (PVCs). Multiple DLCIs are allowed for each protocol type supported, as well as multiple protocols via one DLCI. The Local Management Interface (LMI), which provides status inquires between the 3174 and the frame relay network, is support for LMI Revision 1, Annex D, and CCITT formats. The 3174 can also communicate directly with another 3174 (DTE to DTE) without using a frame relay network.

Compatibility

For SNA 3270, LAN Gateway, and APPN, the 3174 Frame Relay uses IEEE 802.2 Logical Link Control. With this interface, the 3174 interconnects with other products such as 3745, RouteXpander/2, AS/400, and other 3174s. The 3174, or a downstream PU using 3174 LAN gateway support, uses Frame Relay Boundary Node function in NCP V7R1. The 3174 APPN Network Node can interface to other APPN nodes, such as RouteXpander/2, 3174, AS/400, and VTAM/NCP.

TCP/IP on the 3174 can use a frame relay network to a TCP/IP host or IP router, such as the 6611 or a 3745 using the Frame Relay Frame Handler support in NCP.

All these frame relay functions can coexist on the same 3174 (with sufficient storage) and all the IP, SNA, and APPN traffic can flow on the same DLCI (if the same destination) or separate DLCIs.

The Frame Relay feature requires Configuration Support-C (feature #6010, #6015, #4710, #4730, and #4740).

Limitations

Frame Relay is not supported via communication through the Concurrent Communications Adapter (CCA) or ISDN BRI Adapter.

Licensed Internal Code base functions

The following base 3174 functions are provided in Configuration Support-A Release 5, Configuration Support-B and Configuration Support-C.

Customization

The 3174 customization has the following features:

  • A central site customization facility (see "Central Site Customizing", below, under "Offline Utility Procedures".)
  • Electronic distribution of customization parameters and/or data via the Central Site Change Management function.
  • Use of words and phrases on the customization panels, as opposed to only numbers and symbols.
  • Error messages presented on screen
  • Optional selection of printer authorization matrix definition panel, with self-explanatory prompts
  • Reduced number of questions for equivalent function
  • Reduced diskette swapping
  • Expanded use of defaults
  • Reduced machine execution time.

Offline Procedures

Offline procedures are provided to aid in the configuring and managing of 3174 Licensed Internal Code and to provide offline diagnostic functions. They are invoked from a "master menu" panel that is displayed on a control unit terminal attached to port 0. The 3174 offline procedures include:

  • Customize the Control Diskette: Provides the ability to configure control unit Licensed Internal Code, define printer authorization matrix, merge RPQs, and modify keyboards.
  • Merge Downstream Load: Provides the ability to merge the Licensed Internal Code required by two or more downstream-load terminals on to one diskette. Use of this procedure requires a second diskette drive.
  • Copy Files: Through its seven variations, provides a means of duplicating diskettes, copying specific data areas, and copying with configuration modifications from one control diskette to another. The Full Copy and Modify and Copy options require a second diskette drive. This feature is not required for the other copy files options, but their usage is enhanced with it, since the need for diskette swapping is reduced.
  • Diagnostics: Provides a full range of offline diagnostics. Diagnostics are selected from a menu panel when this utility is invoked.
  • Licensed Internal Code Upgrade: Provides a process to update a newly released control diskette with the configuration data from the down level control diskette, thus greatly reducing the time required to execute this task.
  • Identify Customizing Keyboard: Expands the types and configurations of keyboards from which the 3174 customization process can be executed.
  • Central Site Customization: Enhances the management, distribution, and control of Licensed Internal Code for 3174 control units in a network. It provides the ability to create offline, a central site library of network control unit data; create, modify, browse, or delete library members; and generate customized control diskettes for mailing to network 3174s. A second diskette drive is required to use this procedure. Although not required, the 2.0MB Storage Expansion feature (#1014) is recommended to facilitate generating diskettes for network control units by reducing the time and manual intervention required to read individual/duplicate control diskettes. The procedure is a prerequisite for Central Site Change Management.

APL2 Characters Support

The APL character set is expandable to 138 characters, this is called APL2. Some APL compilers use these additional characters. The supported characters are: Diamond, Quad Null, Iota Underbar, Epsilon Underbar, Left Tack, Right Tack, Equal Underbar, Squished Quad, Quad Slope, and Dieresis Dot. All ten characters are supported to the host, however, the Diamond, Left Tack, and Right Tack are not supported on IBM APL2 keyboards. The displays supported with APL2 keyboards are: 3191 Models D, E, L, the CUT version of 3192, and 3472 InfoWindow.

Intelligent Printer Data Stream (IPDS)

Intelligent Printer Data Stream (IPDS) is supported for the IBM 4224, 3812, and 3816 Printers. These printers use a 3270 Extended Data Stream structured field approach to manage and control printer processes. IPDS is designed to allow the presentation of text, raster images, vector graphics, bar codes, and previously stored overlays at any point on a page. IPDS commands within the data stream also enable the host processor to control media handling, error recovery, and the downloading and management of symbol sets (fonts) and printer stored objects, such as overlays and page segments. The printer can later use these stored objects to construct a printed page. IPDS can significantly reduce the load on the host processor.

Multiple Logical Terminals (MLT)

Multiple Logical Terminal support enables IBM 3270 fixed-function (CUT-mode) displays attached to any model IBM 3174, regardless of host connection protocol, to interact with up to five host sessions. The host sessions can be directly connected to a single IBM host and one or more ASCII host(s). Each session can be connected to only one host at a time. Except as noted below, each session is processed as though it were defined on a separate, but identical display.

Each session utilizing the connection to an IBM host requires a 3174 session address known to the IBM host, i.e. a host session address. The host connection and associated session address is defined during 3174 customization. The available number of IBM host sessions is constrained by the host connection mode (SNA or non-SNA).

The ASCII host connection requires the Asynchronous Emulation Adapter (AEA) feature (#3020) to be installed. Access to the ASCII host is accomplished on a session basis through a connection menu or default destination procedure as specified in the 3174/AEA customization procedure. Each ASCII host connection utilizes one AEA port. A session that is used for a connection to an ASCII host is not required to have an IBM host address assigned to it.

The display screen and keyboard are owned by a single session at a time. Other sessions associated with the display are maintained in the 3174. Operator access to these sessions, whether they are in IBM hosts or ASCII hosts, is accomplished via a Change Screen key sequence that varies by keyboard layout. This key sequence causes the display screen and keyboard ownership to be transferred to the next session in a round-robin fashion. Host access to a particular session is processed independent of the other session states. In particular, the display screen and keyboard are not affected unless the session being accessed is the current owner.

Each session associated with a display is defined by the characteristics such as screen size and extended attribute buffer (EAB) of the display. If the display has Programmed Symbols feature(s), its usage is limited to the primary (first) session. The Explicit Partition and windowing feature is not supported if more than one session is defined for this display.

IBM fixed-function displays supported for MLT sessions include the 3179, 3180, 3278, 3279, 3191, 3192, 3471, 3472, 3481, and 3482. Other displays that fully emulate one of the supported terminals can also take advantage of the MLT capability. Printers, including SOEMI devices, are limited to a single session and host connection. DFT device support is not affected by MLT. Displays and printers attached via the AEA do not have MLT capabilities.

Six levels of MLT support are selectable during 3174 customization. Level zero allows a customer to choose no MLT support. Levels one, two, three, four, and five reserve specific amounts of storage which allow various combinations of displays and session counts to be defined.

When combined with other features and functions like the Asynchronous Emulation Adapter (#3020) and Central Site Change Management, additional storage may be required. See "Configuration Support-A Storage Requirements".

Response Time Monitor

Response Time Monitor is a base function in the control units. It provides for enhanced network management for CUT devices by permitting the accurate measurement and recording of transaction times between an inbound host attention and a user-defined transaction end.

Response Time Monitor Transaction-end Definition

A Response Time Monitor Transaction-End definition is available to accurately measure the total elapsed time for transactions with host applications that unlock the keyboard before the actual data requested by the terminal operator is provided by the application. The transaction-end definition can be selected during 3174 customization or in SNA environments can be selected by the host. In an operational environment the total elapsed time between activation of an attention interrupt (AID) key to receipt of the transaction end identifier is measured. A DFT device may not support all current 3174 transaction end definitions. RTM support is disabled for DFT devices if the DFT device does not support the 3174 transaction-end defined in 3174 customization.

Central Site Change Management

Allows electronic distribution of customization parameters and/or data to network 3174s. The Central Site Customizing Utility function is required on a 3174 Model 11R that is designated as the central site control unit. The customization parameters and/or data for control units in the network are electronically distributed via NetView* Distribution Manager Version 1 Release 2, or later, in the IBM central site host using the LU 6.2 support provided in the ACF/VTAM Version 3.2. Electronic distribution of customization parameters is to any Model of the 3174 in a nondisruptive mode. Electronic distribution of other data may require network site intervention depending on that network 3174s Model and/or hardware features installed. The central site control unit requires either a second diskette drive or the 20MB Fixed Disk Drive optional feature. The 20MB Fixed Disk Drive feature is not a prerequisite but is desirable for some 3174s participating in Central Site Change Management. Additional storage may be required when combined with other functions (see "Configuration Support-A Multiple Sessions and Storage Chart"]. In addition to providing the electronic distribution support for central site control units, CSCM also provides the complementary support to receive customization parameters and/or data at the network control units.

Network Asset Management

Network Asset Management responds to SNA host requests for Vital Product Data (VPD) information relating to the SNA 3174 and supported attached devices (see chart below for level of VPD support). Full VPD support includes Machine Type, Model Number, Serial Number (Plant of Manufacture (POM) concatenated with the sequence number) and Product Class (IBM or non-IBM). For all locally attached devices, including those not supporting VPD, the 3174 will also respond to the SNA host request with the 3174 port address, an indication if the device is currently powered on, and an indication whether there has been any power-on/off activity for the device since the last time the 3174 responded to a host request for VPD information. All information relating to the attached devices will be maintained in the 3174 even when the attached device is powered off.

The Network Asset Management function requires NetView Release 3, or later installed in the IBM MVS/XA, MVS/ESA, VM/SP, or VM/XA host that owns the 3174 and support provided in ACF/VTAM Version 3, Release 1.1, or later.

For processing the Network Asset Management data gathered by NetView, a product such as Service Level Reporter (SLR), Information Management, or a user provided program is required.

Configuration Support-A Storage Requirements

Some combinations of the features and functions described in the "Optional Features" and the Configuration Support-A, Release 5 section may require additional storage. Before attempting to decide on the total amount of storage required, the level of MLT support should be determined.

MLT Weighting Factors for Configuration Support-A

Each IBM CUT display supported for MLT sessions requires a certain amount of storage based on the number of sessions desired, its screen size and screen characteristics. This storage requirement is called a "weighting factor". The sum of the weighting factors for each terminal on a given 3174 determines the required level of MLT (level 0, 1, 2, 3, 4, or 5) to support the required MLT sessions. The chart below should be used to determine the level of MLT support required.

*----------------------------------------------*
| Display Characteristics | Number of Sessions|
|Row x | Total | Per Terminal |
|Column | Characters | 1 | 2 | 3 | 4 | 5 |
|-------+------------------+---+---+---+---+---+----------*
| 24x80 | (1920), no EAB | 0 | 3 | 6 | 9 | 12| Weighting|
| 24x80 | (1920), with EAB | 0 | 5 | 10| 15| 20| |
| 32x80 | (2560), no EAB | 0 | 5 | 10| 15| 20| Factors |
| 32x80 | (2560), with EAB | 0 | 9 | 18| 27| 36| |
| 43x80 | (3440), no EAB | 0 | 5 | 10| 15| 20| Per |
| 43x80 | (3440), with EAB | 0 | 9 | 18| 27| 36| |
| 27x132| (3564), no EAB | 0 | 5 | 10| 15| 20| Terminal |
| 27x132| (3564), with EAB | 0 | 9 | 18| 27| 36| |
*---------------------------------------------------------*


Note: EAB (Extended Attribute Buffer) refers to the ability of some displays to highlight or display in 7 color mode, individual display character positions.

Note: Some CUT displays support a number of screen sizes and allow the user to select a screen size as part of display set-up mode. If these displays support the Extended Function feature, then the largest screen size supported by the device must be used to determine its weighting factor. If the display does not support this feature, then the screen size chosen during set-up mode should be used.

  • For MLT level 0, the sum of weighting factors is 0.
  • For MLT level 1, the sum of weighting factors must not exceed 64.
  • For MLT level 2, the sum of weighting factors must not exceed 128.
  • For MLT level 3, the sum of weighting factors must not exceed 416.
  • For MLT level 4, the sum of weighting factors must not exceed 864.
  • For MLT level 5, the sum of weighting factors must not exceed 1408.

The following table can be used to determine the amount of storage required for the combinations of features and functions desired. This is done by identifying the feature/functions desired on the appropriate hardware and change management configuration. The intersection of the selected column and row determines the storage requirement for that feature/function combination.

Note: The maximum storage available when using Configuration Support-A Release 5 is 4.0MB. If you customize for items requiring more than the total amount of storage installed, a deconfiguration of some of these items will occur during IML.

Configuration Support-S Release 5

Note - If you are planning to attach a large number of DSPUs to a 3174 LAN Gateway controller (Token-Ring or Ethernet), thruput for locally attached terminals may not be acceptable (e.g. poor response times, decreased data transfer rates, or status code 379-02 is displayed). Please consult the 3174 Performance Guidelines on HONE to evaluate the 3174 performance and capacity factors that can be expected in your desired configuration and application/host environment.

Configuration Support-S is the supporting Licensed Internal Code shipped with the IBM 16/4M Bps Token-Ring Network Gateway optional feature (#3026). See Optional Feature #3026 description for further details.

Configuration Support-S also supports all applicable Configuration Support-A Release 5 functions for locally attached devices except support for the 3299-032. This includes:

  • Customization (other Token-Ring devices addresses are also customized)
  • Response Time Monitor
  • Response Time Monitor Transaction-end Definition
  • Offline Procedures
  • Intelligent Printer Data Stream (IPDS)
  • Multiple Logical Terminals (MLT)
  • SNA Logical Unit Support
  • National Language Support
  • APL2 Characters Support
  • Central Site Change Management (not supported as a central site controller)
  • Network Asset Management
  • Asynchronous Emulation Adapter

Configuration Support-S Storage Requirements

Some combination of the features and functions described in the "Optional Features" and the Configuration Support-S, Release 5 section may require additional storage. Before attempting to decide on the total amount of storage required, the level of MLT support should be determined.

MLT Weighting Factors for Configuration Support-S

Each IBM CUT display supported for MLT sessions requires a certain amount of storage based on the number of sessions desired, its screen size and screen characteristics. This storage requirement is called a "weighting factor". The sum of the weighting factors for each terminal each on a given 3174 determines the required level of MLT (level 0, 1, 2, 3, 4,or 5) to support the required MLT sessions. The chart below should be used to determine the level of MLT support required.

*----------------------------------------------*
| Display Characteristics | Number of Sessions|
|Row x | Total | Per Terminal |
|Column | Characters | 1 | 2 | 3 | 4 | 5 |
|-------+------------------+---+---+---+---+---+----------*
| 24x80 | (1920), no EAB | 0 | 3 | 6 | 9 | 12| Weighting|
| 24x80 | (1920), with EAB | 0 | 5 | 10| 15| 20| |
| 32x80 | (2560), no EAB | 0 | 5 | 10| 15| 20| Factors |
| 32x80 | (2560), with EAB | 0 | 9 | 18| 27| 36| |
| 43x80 | (3440), no EAB | 0 | 5 | 10| 15| 20| Per |
| 43x80 | (3440), with EAB | 0 | 9 | 18| 27| 36| |
| 27x132| (3564), no EAB | 0 | 5 | 10| 15| 20| Terminal |
| 27x132| (3564), with EAB | 0 | 9 | 18| 27| 36| |
*---------------------------------------------------------*


Note: EAB (Extended Attribute Buffer) refers to the ability of some displays to highlight or display in 7 color mode, individual display character positions.

Note: Some CUT displays support a number of screen sizes and allow the user to select a screen size as part of display set-up mode. If these displays support the Extended Function feature, then the largest screen size supported by the device must be used to determine its weighting factor. If the display does not support this feature, then the screen size chosen during set-up mode should be used.

  • For MLT level 0, the sum of weighting factors is 0.
  • For MLT level 1, the sum of weighting factors must not exceed 64.
  • For MLT level 2, the sum of weighting factors must not exceed 128.
  • For MLT level 3, the sum of weighting factors must not exceed 416.
  • For MLT level 4, the sum of weighting factors must not exceed 864.
  • For MLT level 5, the sum of weighting factors must not exceed 1408.

Determining Configuration Support-S Storage Requirements

Any one of the feature/function combinations listed in the tables below is operable within its listed storage requirement. (Features/ functions not shown in the table, do not increase storage requirements above that listed in the table.)

The following tables can be used to determine the amount of storage required for the combinations of features and functions desired. This is done by identifying the feature/functions desired on the appropriate hardware and change management configuration. The intersection of the selected column and row determines the storage requirement for that feature/function combination. This storage requirement should be recorded. From the Token-Ring Gateway - DSPU table, select the desired number of DSPUs. Add the two values of storage requirements. The final result is the storage requirement for your configuration.

Note: The maximum storage available when using Configuration Support-S Release 5 is 4.0MB. If you customize for items requiring more than the total amount of storage installed, a deconfiguration of some of these items will occur during IML.

Configuration Support-B

Configuration Support-B consist of four functional releases. In addition to the functional enhancements, certain releases provide for additional 3174 Models support. Release 2 provides support for 3174 models.

3174 customers making a decision to install the Token-Ring gateway capability will benefit from a functional/performance standpoint when they install Configuration Support-B or C and the Type 3A Communication Adapter rather than the 3270 Token-Ring gateway feature (F/C 3026).

Functional Improvements In Configuration Support-B Release 1

Multihost connectivity via the Concurrent Communication Adapter

The Multihost connectivity provided by Configuration Support-B Release 1 and the Concurrent Communication Adapter feature provides cost effective, flexible and concurrent access to multiple 3270 host applications resident in more than one host from a terminal attached to the 3174. Each Concurrent Communication Adapter provides access to a single IBM host for synchronous teleprocessing communication over a TP link at speeds up to 64K bps using SNA/SDLC or X.25 protocols and up to 19.2K bps using BSC protocols.

Depending on the model, up to two Concurrent Communication Adapter features may be installed in the 3174. When two of these features are installed, up to three 3270 hosts may be accessed concurrently (e.g. Primary, Concurrent Communication Adapter #1 and Concurrent Communication Adapter #2). When an Asynchronous Emulation Adapter (AEA) is present, asynchronous ASCII applications are also accessible from the same 3174. ASCII terminals attached to the 3174 through the AEA can access the IBM host via the primary link only.

Single Link Multihost Support Token-Ring

Single Link Multihost Support over the Token-Ring network is a function that enables the 3174 Models 13R (Token-Ring attached controllers) and 3174 Models operating in the alternate configuration mode with FC #3044, to concurrently access up to a total of eight (8) IBM hosts via the primary Token-Ring link through gateways attached to the Token-Ring network. The primary host-attachment can be either a Type 3 Token-Ring (4M Bps) Adapter or a Type 3A (16/4M Bps) Dual Speed Communication Adapter.

Single Link Multihost Support supports up to five concurrent sessions for each attached terminal. The five sessions can be distributed among the eight 3270 application hosts in any manner, and the terminal operator can "hot-key" switch among them without having to logoff/logon.

Note: This function is provided entirely by Configuration Support-B and does not require the Concurrent Communication Adapter feature.

Remote Token-Ring Group Poll

The 3174 Remote Token-Ring gateway has been enhanced to support an option to accept and process a Group Poll command from NCP for all of the PU (Physical Unit) addresses on a single 3174 controller configured as a gateway. The Polling Performance Enhancement enables customers to configure NCP to send a Group Poll to the remote gateway. The 3174 will respond with data from any one of the Token-Ring devices that has data pending. This function will reduce the overall polling from NCP and eliminate unproductive polls; thereby increasing the efficiency of the communications link and improving the response time for the end-users.

The Group Poll capability in the 3174 requires that a Small Program Enhancement (SPE) be installed in both the Network Control Program (NCP) and the System Support Program (SSP) at the host site.

A maximum number of sixteen (16) remote 3174 Token-Ring gateway controllers may be multidropped on a single half duplex data mode communications link utilizing the Group Poll function.

Multiple Logical Terminal Enhancements

Enhanced Multiple Logical Terminal (MLT) Support includes:

  • Delayed Host Notification for Secondary Logical Terminals (LTs). The host will not be notified of the presence of secondary MLT/host sessions until the session is first selected (e.g.,: via Power-on or Change Screen key).
  • Implementation of a Logical Terminal Assignment (LTA) table. This table, defined during customization, identifies the MLT/host sessions accessible by each 3174 device port. Storage is allocated only for secondary sessions defined in the Logical Terminal Assignment (LTA) table. Storage is not allocated for all sessions defined in the Port Assignment Specification Table (PAST).

Additional Functional Improvements

  • The functions of the Token-Ring gateway have been integrated with other 3174 function in Configuration Support-B. The Type 3A Token-Ring adapter is ordered separately as F/C 3044 (or could have been previously installed via F/C 3030 or F/C 3026); the installation and customization is accomplished as before. With 3174 Model 11R, up to 250 DSPUs can be defined. However, the number of active devices that can be supported is dependent on the 3174 storage installed and the end-user response time objectives.
  • Support for the 2.4 MB diskette in 2.4 MB mode to accommodate the additional function being announced.

Functional Enhancements in Configuration Support-B Release 2

Central Site Control Facility

The Central Site Control Facility extends the capability for customers who intend to manage the 3174s in their network from a central location. The previously announced Central Site Customization Utility and Central Site Change Management facilities provide centralized control and maintenance of the customization parameters, patches, Licensed Internal Code EC release levels, RPQs, and downstream load microcode.

With the release of Central Site Control Facility, centralized control of the 3174 in an SNA environment is expanded to include problem determination and network management. Central Site Control Facility allows a NetView operator to execute 3174 online diagnostic tests on remote 3174 controllers. With central site access to these functions, the customer can:

  • Collect and reset error information and event logs.
  • Gather response time information.
  • Initiate corrective procedures based on problem analysis.
  • Display the names of the 3174 Licensed Internal Code data objects (canonical names) at a network 3174 controller.

The following 3174 online diagnostic tests are executable by the NetView operator via Central Site Control Facility:

  • Test 1 - Display event logs and response time log
  • Test 2 - Display configuration panels
  • Test 3 - Display status summary
  • Test 4 - Reset logs and cable errors
  • Test 5 - Display and enter Vital Product Data (Option 5,6 is not supported by Central Site Control Facility.)
  • Test 6 - Display control blocks (Option 6,2 is not supported by Central Site Control Facility. Option 6,2,n,m is supported by Central Site Control Facility.).
  • Test 9 - LAN tests on both the 3174 Gateway and LAN attached controllers
  • Test 10 - Port wrap tests
  • Test 11 - Trace control (initiate and retrieve)
  • Test 12 - Asynchronous Emulation Adapter tests (Option 12,1 is not supported by Central Site Control Facility.)
  • Test 13 - ESCON adapter Tests
  • Test 14 - 3174 Operator Functions
  • Test 15 - 3270 Host Status Summary
  • Test 16 - ISDN Adapter Test (Config C only)
  • Test 17 - APPN Status (Config C only)
  • Test 18 - Frame Relay status (Config C only)

Note: Central Site Control Facility requires that the NetView Central Site Control Facility feature be installed on the NetView system. Central Site Control Facility is supported by NetView Release 3 when running on the MVS/XA and VM operating systems.

Enhanced Network Asset Management

The Enhanced Network Asset Management function provides the following enhancements:

  • User-definable Vital Product Data for products not providing Vital Product Data.
  • User-definable Data for customer defined data related to a 3174 port/device
  • Extended Vital Product Data for the 3471, 3472, 3481, and 3482 display stations

User-definable Vital Product Data support is being added for products that do not support the Vital Product Data function (i.e., early 3270 displays and printers, ASCII devices, PCs and PS/2s* running DOS or OS/2* Standard Edition). The enhancement will allow the user to input information such as machine type, model number, serial number, plant of manufacture, and product class (IBM or non-IBM) for devices that do not supply Vital Product Data. This information will be stored in the 3174. The user will also be able to enter this data via NetView and Central Site Control Facility.

The User-definable Data function will permit the customer to define up to 50 bytes of free format data for each port on the 3174 (3270 and AEA), and 50 bytes of data for the 3174 itself. The contents of the free formatted field are completely user defined. An example usage would be to store information relating to the physical location of the 3174 and each of the attached displays.

Configuration Support-B Release 2 provides extended Vital Product Data to the 3471 Model B, 3472, 3481, and 3482 display stations that enables the customer to enter an additional eight fields of user-definable data. Each of the eight fields contains a 15 byte label and a 25 byte data area. To ensure consistent format, the 3174 provides the display with a label template for extended Vital Product Data. The contents of the label area are defined during 3174 customization and cannot be overwritten by the end-user. The label template can be distributed via the Central Site Change Management facility to all 3174s in the network.

The extended Vital Product Data function in Enhanced Network Asset Management requires that a Small Programming Enhancement (SPE) be installed in NetView Release 3 at the host site. The SPE was available on June 29, 1990.

Enhanced Trace Facility

The 3174 Enhanced Trace Facility is an internal system facility used to trace the execution of 3174 Licensed Internal Code and record 3174 memory and register contents. The Enhanced Trace Facility is an integral part of the 3174 reliability and serviceability functions and is intended to improve the problem determination capabilities of the 3174.

The following changes are included in the Enhanced Trace Facility:

  • Perform existing and new trace functions using a panel environment (as opposed to a command environment)
  • Store and update trace setup commands
  • View the trace data online

The Enhanced Trace Facility is supported by the Central Site Control Facility.

Data Streaming

The Data-streaming function controls the data transfer rate between the 3174 and the local channel through control tag sequences generated by the channel and the control unit. The data rate is determined by the frequency and rate of handshaking sequences required between them. This function is used only for read and write commands and is not applicable for sense or control commands. Data streaming will allow multiple control unit read/write operations to occur before the corresponding channel response sequences, thus permitting data to be sent in large segments.

Data streaming is enabled by selecting either low or high-speed data rate at 1.25 or 2.5 MBytes/second data rate during the customization of the 3174. Current 3174 low and high-speed data rates are .65 and 1.25 MBytes/second. The host control program must also be customized to support Data streaming and command retry on the channel to which the 3174 is attached. The 3174 must be customized to support command retry when Data-streaming mode is selected.

Multiple Logical Terminal (MLT) level 6

An additional level of MLT support is provided by Multiple Logical Terminal (MLT) level 6. The 3174 can be configured to allow for a maximum number of logical terminals (LTs) to be defined for both 3270 CUT devices and ASCII devices emulating 3270 CUT mode operation. Multiple Logical Terminal (MLT) level 6 allocates a storage increment of 1.5MB to support five LTs on each CUT and ASCII port. The maximum number of sessions supported by Multiple Logical Terminal (MLT) level 6 in the 3174 Establishment Controller is 253. Note that MLT level 6 is not required to support Multiple Logical Terminals on ASCII devices, but is required when storage requirements for MLT storage weighting factors for CUT and ASCII devices exceed 1152.

Asynchronous Emulation Adapter (AEA) Enhancements

The Asynchronous Emulation Adapter enhancements consist entirely of functional changes in the Licensed Internal Code. The implementation of the AEA enhancements will increase the storage requirements and may necessitate additional storage. Refer to the Configuration Support-B Storage Requirements section for additional storage requirement information.

The following enhancements are added to the AEA support:

  • Additional ASCII Emulation Support for 3270 CUT terminals connected to ASCII host(s).
    • Data General** Dasher D210
    • DEC** VT220 (7 and 8 bit)
    • Extended Attribute Buffer (EAB) support for 3270 terminal access to ASCII hosts (uses the 3270 terminal EAB to provide enhanced mapping of ASCII character attributes).
  • Improved 3270 Emulation for ASCII terminals connected to IBM 3270 host applications.
    • Multiple Logical Terminal (MLT) access for ASCII Terminals to the primary IBM host on the 3174 primary interface
    • Additional terminals supported for 3270 Emulation (attached printer support is also provided for these terminals):
      • ROLM** Cypress, Cedar, Juniper
      • DEC** VT220 (7 or 8 bit)
      • Tektronix** 4205
      • WYSE** 50/60
    • User Defined Translate Table (UDX) for ASCII Terminals
    • User Defined Terminal Table/Keyboard Mapping (UDT) for ASCII Terminals
    • Miscellaneous 3287 Printer RPQ support for ASCII Printers
    • Additional Per Port Password capability
    • A device type (i.e., ASCII plotter) for use only as System Printer

Integration of RPQs into Configuration Support-B Release 2

Configuration Support-B, Release 2 provides for the integration of RPQs 7L0647, 7L0665, 8K1387, and 8Q0688.

  • Local Format Storage (previously supported as RPQ #8X0024 in Configuration Support-A)

    The Local Format Storage function provides for host controlled loading of screen format information (MAPS) into the 3174 control storage and for subsequent run-time presentation of the stored MAPS. This function requires a customer written application program to generate and transmit the MAPS to the 3174. The CICS Basic Mapping Support fully supports the presentation of previously loaded MAPS stored in the 3174.

    The 3174 Local Format Storage function is designed to be compatible with the IBM 8100 Outboard Formatting support that is available on the following levels of CICS:

    • CICS/OS/VS V1 R7
    • CICS/OS/MVS V2 R1
    • CICS/OS/ESA V3 R1
    • CICS/DOS/VS V1 R7

    While some tailoring/modification of host software may be required to take advantage of this function, use of this function can result in significant reduction of traffic on host to control unit transmission facilities, thus improving terminal response time and potentially lowering bandwidth costs for the host connection.

  • 3174/AEA RPQ 8Q0688 (AEA 8 bit support) Integration

    The integration of the RPQ permits NLS support for the DEC VT220** for both 3270 Emulation and for ASCII Emulation. Note that the same code table restrictions exist as with the original RPQ (the level of CECP support depends on the specific host code pages, controller code pages, and the specific display or printer).

  • Configuration Support-B Release 2 provides for the integration of RPQ 7L0665 into the 3174 Establishment Controller. This support provides extended graphics mode support when using Country Extended Code Page (CECP) displays connected to an IBM 3270 application program. This function supplies additional keyboard characters selected through a combination of Alternate and Shift keys. The resulting new keyboard mapping constitutes the Keyboard ID 100, which is a subset of ISO 8884. It provides all Latin based language accents as diacritic accented characters to allow creation of any accented character required by supported languages. The languages supported by integration of certain RPQs into base function are the same as those supported by RPQ 7L0665.
  • The Device Timeout Extension (RPQ 8K1387) is also integrated into Configuration Support-B, and can be activated during customization. This function adds an extra delay to the interface between the 3174 and an attached device. It provides 100 microseconds instead of 50 microseconds for a device to respond to any Read operation initiated by the 3174 controller. This support enables the 3174 to attach the IBM 5209 Link Protocol Converter or similar devices which require increased media delay between the 3174 controller and the device.

Other Configuration Support-B, Release 2 Enhancements

  • Type-Ahead allows an operator to enter keystrokes when the keyboard normally would have been locked. This can be for data keys or 3270 Aid keys. If the operator knows what is required on the next screen they may key input for that screen immediately after depressing ENTER or a PF Key. Type-Ahead also allows the operator to rapidly pass through unwanted screens from the host. Type-Ahead is used for 3270 CUT-mode terminals and ASCII terminals in 3270 emulation mode operating in Main Frame Interactive (MFI) mode and may be activated during customization.
  • With enhanced Null/Space processing the user can position the cursor via the cursor move keys so that any data keyed in remains where it is on the screen as if the space bar had been used to position the cursor. The operator may insert data into a line which has trailing spaces. The trailing blanks are moved off the end of the line (or field) and discarded. Enhanced Null/Space processing is used for 3270 CUT-mode terminals and ASCII terminals in 3270 emulation mode operating in MFI mode and may be activated by the terminal operator.

Functional Enhancements in Configuration Support-B Release 3

Multiple Hosts for Token-Ring Gateway

This function Gateway allows a Token-Ring attached device to take advantage of the multiple host connectivity options available in the Gateway 3174 Establishment Controller. With this feature, a Token-Ring device can connect to SNA host(s) (channel or SDLC) on the 3174's primary link and/or connect to SNA/SDLC host(s) via Concurrent Communication Adapter(s). This function will optimize gateway costs by accessing multiple host(s) through one 3174. The additional host(s) support can be used to provide additional applications to an existing network or providing a back-up host link. A maximum of two Concurrent Communication Adapters are supported by the gateway.

Single-Link Multihost Support for X.25 Networks

Enables X.25 attached 3174s (11R) to concurrently access up to eight IBM hosts via the primary link. The host must all be accessible via a single X.25 Network.

When used with a Concurrent Communication Adapter (CCA), Single Link Multihost - X.25 also makes it possible to concurrently access up to four IBM hosts via each secondary link that is attached to an X.25 Network. When two CCAs are present, each may access four hosts in addition to the primary host connections. This allows access to up to sixteen X.25 hosts via three physical links.

Single-Link Multihost X.25 support is not available on the 3174 Token-Ring Gateway and is not applicable to AEA device users.

X.21/X.25 Switched Autocall/Autodisconnect

The Autocall/Autodisconnect functions eliminate user intervention to initiate and break a X.21 Switched or X.25 Switched Virtual Circuit connection. Since the X.21 Switched or X.25 Switched Virtual Circuit attachments are made only when a display is active, connection costs are minimized and the customer now has the most cost-efficient use of the switched network resources.

These functions reduce the need for an operator display on Port 0. For security reasons, Port 0 can still manage up to five hosts, and allow the Autocall/Autodisconnect functions to control the other hosts.

The Autocall/Autodisconnect function incorporates the functions of RPQ 7L0661 (X.25 Dial), RPQ 7L0843 (X.25 Dial for DFT), and RPQ 7L0664 (X.21 Dial for DFT).

Enhanced X.25 Support

To improve the performance of some user applications, the 3174 now supports larger PIU sizes for X.25 connections. A PIU size of 521 may be selected as an alternative to the current support of 265. Larger PIU sizes provide more efficient communications.

To remain compatible and current with new network implementations and with other IBM X.25 products, these X.25 enhancements upgrade the X.25 support to conform to the most recent standards. Conformance to SC30-3409-1, which is IBM's X.25 architecture, includes considerations for 1988 CCITT Recommendations X.25 as well as ISO X.25 standards 7776 and 8208.

Duplex Multipoint for 3174 Token-Ring Gateway

The 3174 gateway can be used in a multipoint network with the NCP line configured as a Full Duplex line. In the past, multipoint networks containing 3174 Gateways had to have the NCP line configured as a Half Duplex line. This function allows the multipoint network to offer potentially increased throughput to all users on the line.

Remote IML Options

A new Central Site Control Facility (CSCF) option allows a NetView* operator to IML the 3174 controller remotely from a NetView terminal. This new option provides an online test that allows the user to perform the IML, select the drive from which the IML should occur and choose production, trial or back-level code. This function expands the control the network operator may exercise over the network 3174s.

Additional National Language Support

National Language Support changes include:

The positions of the period and comma key on numeric keyboards have been reversed for Cyrillic IBM Enhanced and IBM Converged keyboards to ease data entry.

The 3174 now supports Keyboard ID 171 for Spanish-speaking countries for all keyboards except IBM Data Entry and IBM Data Entry Keypunch providing additional accent characters. End-users have productivity improvements with a keyboard that matches the written language.

Functional Enhancements in Configuration Support-B Release 4

3270 Port Expansion Feature Support

Provides support of the 3270 Port Expansion Feature which allows up to sixty-four 3270 Category A devices to be attached to a single 3174 Model 11R. The Port Expansion feature consists of hardware that enhances the large cluster controllers to support an additional thirty-two 3270 Category A devices. Increasing the number of 3270 type devices per 3174 allows network expansion without increasing the size of the wiring closet and greatly reduces the price per port of the 3174. Field MESs offer future growth without investing in another 3174 controller.

Multiple Logical Terminal (MLT) level 7

An additional level of MLT support is provided by Multiple Logical Terminal (MLT) level 7. The 3174 can be configured to allow for a maximum number of logical terminals (LTs) to be defined for both 3270 CUT devices and ASCII devices emulating 3270 CUT mode operation. Multiple Logical Terminal (MLT) level 7 allocates a storage increment of 2.048MB to support additional LTs for 64 ports. Multiple Logical Terminal level 7 is required when the sum of the MLT storage weighting factors for CUT and ASCII devices exceeds 1536 (MLT level 6).

Multiple Logical Terminal (MLT) level 8

An additional level of MLT support is provided by Multiple Logical Terminal (MLT) level 8. The 3174 can be configured to allow for a maximum number of logical terminals (LTs) to be defined for both 3270 CUT devices and ASCII devices emulating 3270 CUT mode operation. Multiple Logical Terminal (MLT) level 8 allocates a storage increment of 2.688MB to support five LTs on each CUT and ASCII port. Multiple Logical Terminal level 8 is required when the sum of the MLT storage weighting factors for CUT and ASCII devices exceeds 2048 (MLT level 7).

Character Set and Code Page for Turkey

In this release, the Character Set and Code Page for Turkey will be changed to be Character Set 1250 and Code Page 1026 to support new customer requirements.

Configuration Support-B Storage Requirements

Some combinations of the features and functions described in the "Optional Features" and the Configuration Support-B sections may require additional storage. Before attempting decide on the total amount of storage required, the level of MLT support should be determined.

MLT Weighting Factors and MLT Levels For Configuration Support-B

Each IBM CUT and AEA attached display that is to be supported for MLT sessions requires a certain amount of storage based on the number of sessions desired, the display screen size and screen characteristics. This storage requirement is defined as a "Weighting Factor". The sum of the weighting factor for each terminal on a given 3174 and the physical host link determine the required level of MLT (level 0, 1, 2, 3, 4, 5, 6, 7, 8) to support the required MLT sessions.

MLT sessions on the primary host link are supported via 3174 control storage. MLT sessions via secondary physical host links (i.e. CCA), are supported by internal CCA feature storage. CCA feature storage is not expandable. Each CCA feature supports a maximum of MLT level 2.

The tables below should be used to determine the MLT requirements for the primary host link when multihost support is NOT selected and for the primary host link when multihost support IS selected.

Notes:

  1. Use Table A if NO multihost support (Concurrent Communication Adapter and/or Single Link Multihost Support) is being customized.
  2. Use Table B if multihost support (Concurrent Communication Adapter and/or Single Link Multihost Support) IS being customized. Be sure to sum the weighting factors for the primary and any secondary physical host links (i.e. CCA), when present, separately. The primary host link MLT level is used when determining 3174 control storage requirements. Secondary host link MLT level requirements must be reviewed to ensure they are not greater than MLT Level 2.

*---------------------------------------------------------*


Note: EAB (Extended Attribute Buffer) refers to the ability of some displays to highlight or display in 7 color mode, individual display character positions.

Note: If you are planning storage for ASCII Tektronix 4205s or UDT tables for which transparency is being defined, you must add additional storage. Base the additional storage amounts on screen size. If the display is 24 X 80, add 2 KB more storage; if the display is 30 X 80, add 4 KB more storage. If you are planning for only one session on an ASCII display, no additional storage is required

Note: Some CUT displays support a number of screen sizes and allow the user to select a screen size as part of display set-up mode. If these displays support the Extended Function feature, then the largest screen size supported by the device must be used to determine its weighting factor. If the display does not support this feature, then the screen size chosen during set-up mode should be used to determine the display's weighting factor.

For Configuration Support-B, some changes were made for the Extended Function feature support. For devices which support this feature, the largest screen size should only be used to determine the weighting factor for the session that can communicate with a SNA host. Also, a customization option was added that disables the ability of the 3270 host to BIND the display for a screen size larger than the size selected at display set-up time. In other words, when this option is used, the screen size chosen at display setup mode should be used to determine the display's weighting factor. For a list of the displays that support the Extended Function feature, refer to Chapter 6 of the 3174 Planning Guide (GA27-3862)

Note: EAB (Extended Attribute Buffer) refers to the ability of some displays to allow extended highlighting (reverse video, blinking and underscore), extended color (seven colors), Programmed Symbols, etc.

Note: If you are planning storage for ASCII Tektronix 4205s or UDT tables for which transparency is being defined, you must add additional storage. Base the additional storage amounts on screen size. If the display is 24 X 80, add 2 KB more storage; if the display is 30 X 80, add 4 KB more storage. If you are planning for only one session on an ASCII display, no additional storage is required

Note: Some CUT displays support a number of screen sizes and allow the user to select a screen size as part of display set-up mode. If these displays support the Extended Function feature, then the largest screen size supported by the device must be used to determine its weighting factor. If the display does not support this feature, then the screen size chosen during set-up mode should be used.

For Configuration Support-B, Release 4 some changes were made for the Extended Function feature support. For devices which support this feature, the largest screen size should only be used to determine the weighting factor for the session that can communicate with a SNA host. Also, a customization option was added that disables the ability of the 3270 host to BIND the display for a screen size larger than the size selected at display set-up time. In other words, when this option is used, the screen size chosen at display setup mode should be used to determine the display's weighting factor. For a list of the displays that support the Extended Function feature, refer to Chapter 6 of the 3174 Planning Guide (GA27-3862)

Note: If CCAs are installed, do not count MLT sessions assigned to the secondary physical host links (i.e., CCA) when determining the weighting factors for 3174 control storage. Be sure, however, to confirm that each secondary host link (i.e., CCA) requirement does not exceed MLT Level 2.

Based upon the sum of the weighting factors selected using Table A or B, either use that sum or the appropriate weighting number (Configuration Support-B, Release 4 or Configuration Support-C) to determine the appropriate MLT Level required:

  • For MLT level 0, the sum of weighting factors is 0.
  • For MLT level 1, the sum of weighting factors must not exceed 64.
  • For MLT level 2, the sum of weighting factors must not exceed 128.
  • For MLT level 3, the sum of weighting factors must not exceed 512.
  • For MLT level 4, the sum of weighting factors must not exceed 896.
  • For MLT level 5, the sum of weighting factors must not exceed 1152.
  • For MLT level 6, the sum of weighting factors must not exceed 1536.
  • For MLT level 7, the sum of weighting factors must not exceed 2048.
  • For MLT level 8, the sum of weighting factors must not exceed 2688.

Determining Configuration Support-B Control Storage Requirements

Any one of the feature/function combinations listed in Tables 1 and 2 is operable within its listed storage requirement. Features and functions not shown in the tables, do not increase storage requirements above that listed.

The following tables can be used to determine the amount of storage required for the combination of features and functions desired. 3174 Model 11R:

  1. Using TABLE 1, add the storage weighting factors for all desired functions to the base control storage weight (1661).
  2. If Gateway or Gateway/CCA support is required, used Table 2 to determine the additional storage requirement for the Gateway or Gateway/CCA combination.
  3. Using the above total, refer to TABLE 3 determine the total 3174 control storage required.

displayed). Please consult the 3174 Performance Guidelines on HONE
to evaluate the 3174 performance and capacity factors that can be
expected in your desired configuration and application/host
environment.

  1. Select whether the primary interface is channel or remote attached. If channel attached, determine if the maximum RU size is 4KB. Use the appropriate section of the table based on the maximum RU size.
  2. Determine the number of Downstream Physical Units that will be connected through the primary host link, if any.
  3. Determine the number of Downstream Physical Units that will be connected through the CCA links, if any. Note: There is a maximum of 50 DSPUs per CCA link.
  4. Using these two numbers, locate the specific storage increment that will support this configuration. This is the additional storage needed. Note: The maximum number of DSPUs connected through the 3174 Gateway with the Type 3 adapter is 140. The maximum DSPUs for the Type 3A adapter is 250 for 4KB RUs. 8KB RUs support a maximum of 100 DSPUs.

As examples:

  1. Assume: Local gateway, 4KB RUs, with 64 primary PUs, and 30 CCA PUs, then the additional amount of storage required for this gateway function is 1536KB.
  2. Assume: Local gateway, 8KB RUs, with 64 primary PUs, and 30 CCA PUs, then the additional amount of storage required for this gateway function is 2048KB.

If you customize for items requiring more than 6.0MB of storage, a deconfiguration of some features/functions will occur during IML.

Note: If you customize for items requiring more than 2.0MB of storage, a deconfiguration of some features/functions will occur during IML.

Note: A minimum of 4.0MB of control storage is recommended when using the off line Central Site Customization Utility (CSCU), Generate Control Diskette procedure, to generate control diskettes. This will reduce the time and manual intervention required for control diskette generation.

Configuration Support-C

Configuration Support-C supports all the functions in Configuration Support-B in addition to the enhancements listed below. In addition to the functional enhancements, certain releases provide for additional 3174 Models support.

Functional Improvements in Configuration Support-C Release 1

US, AP, EMEA--->

ISDN Basic Rate Interface Adapter support

The 3174 ISDN Basic Rate Interface support enables remote workstations to communicate at 64 Kbps over high-quality end-to-end digital networks. It supports up to eight remote workstations without disrupting current upstream host communications. Included in the ISDN support are:

  • ISDN Remote Gateway Group Poll
  • ISDN Remote Gateway Duplex Multipoint
  • ISDN Gateway Multiple Upstream Host via ESCON
    <---US, AP, EMEA

Advanced Peer-to-Peer Networking

Advanced Peer-to-Peer Networking (APPN) feature is an enhancement to IBM's Systems Network Architecture (SNA) and Type 2.1 (T2.1) node architecture which allows inter-connection of systems of widely differing sizes into networks of an arbitrary topology, thereby making it easier to use, more reliable, and more flexible than existing networks.

APPN uses the T2.1 architecture as its base, and is built on the T2.1 low-entry networking function. The 3174 APPN support implements the network node function.

Peer Communication

The Peer Communication Feature provides an integrated version of the Peer Communication RPQ (#8Q0718). It provides the following functions for DOS and OS/2 workstations directly attached to the 3174:

  • Peer-to-Peer communications between DOS and OS/2 workstations allowing them to form a local area network segment.
  • Bridge function to access the IBM Token-Ring network for functions such as print/file servers.
  • Local management function for problem determination of the LAN segment.

Functional Improvements in Configuration Support-C Release 1.1

Dynamic Definition of Dependent Logical Units

3174 Configuration Support-C Release 1.1 supports Dynamic Definition of Dependent Logical Units. The IBM 3174, in conjunction with VTAM, now provides for dynamic growth and change of customer networks by allowing dependent devices to automatically define and activate VTAM LUs when the associated device is powered on.

Supported by both MVS and VM releases of VTAM, the 3174 may be attached to either a channel, an ICA (Integrated Communications Adapter), a LAN (Local Area Network), or an NCP (Network Control Program). At device power-on time, Vital Product Data, as provided by IBM InfoWindow displays, along with 3174 customization information, is supplied to VTAM to accommodate the LU definition. The immediate benefits which can be recognized by a customer are:

  • Reduction in the size of static network definition.
  • Reduced system support requirements.
  • Substantially increased flexibility in the movement of existing devices and the addition of new devices in the network.

This capability is standard in IBM 3174 Configuration Support-C, Release C1.1 and later, and Configuration Support-B Release 4.1 and later. For additional information on required VTAM and NCP releases, see VTAM V3R4 specifications.

Functional Improvements in Configuration Support-C Release 2.0

Split Screen

Split Screen allows the operator of a dependent workstation to display up to five logical terminal sessions on the screen at one time. The operator can determine how much of the screen is devoted to each session, which logical terminal sessions are displayed together with a work group, and the sequence that the logical sessions are displayed within the work group. Also, the operator can determine the "scroll factor" for each session. The JUMP key allows the operator to JUMP from one session to another within the "work group" on the screen; the ZOOM key enables the operator to view an entire logical terminal session at any time; and the CHANGE SCREEN key will display the next "work group". Up to five work groups can be defined per port. Each work group can define up to five LT sessions. Split Screen supports screen formats: 2 = 24 lines X 80-columns, 3 = 32 lines X 80 columns and 4 = 43 lines X 80-columns. The operator can determine how much of the screen is devoted to each session. When displaying two sessions on an equally divided screen in screen format 4, the operator can view almost two complete 24 X 80 sessions.

Host initiated local copy will print the entire presentation space, while operator initiated local copy will only print the portion of the active LT currently displayed. Work groups with 132 character wide sessions and ASCII passthru sessions are displayed in full screen mode only.

Copy from Session to Session

Copy Session to Session allows the operator of a dependent workstation to define a block of data and copy it to multiple locations in the same session, or when using MLT (Multiple Logical Terminal) capability, to multiple locations in multiple sessions. With the function, you can copy to or from any 3270 host session. In addition, you can copy from any ASCII emulation session. 4KB of control storage per port is required in addition to the current calculation for MLT. The maximum size for a copy is 1920 bytes.

HAP Sharing for Local Copy

Local Shared Host Addressable Printer (HAP) support allows a workstation-attached HAP printer to be used as a local copy printer by any workstation attached to the same 3174. Use of a shared HAP printer eliminates the requirement that a local copy printer be attached to each 3174 workstation. 3270 CUT-mode displays and ASCII displays in 3270 emulation mode support the HAP sharing.

Local Print Buffering

Local Print buffering allows an operator to copy screen data to a local copy printer and continue typing while the printer prints. This screen copy capability allows several screen copy jobs to be queued to 3174 control storage. Print buffering is particularly beneficial when multiple users share a single printer for local copy operations. In this environment, users may perform a local copy operation to a shared printer and not have to wait until the printer has completed the previous print job before the keyboard is available for further input.

Calculator Function

The 3174 Calculator function gives CUT displays 10-key calculator capability. Results are displayed in the operator information area (OIA) of the screen and may be used for numeric field input without rekeying. IBM enhanced keyboards or 122 key keyboards are required to support this function.

Token-Ring T1 Timer / Retry Count

Token-Ring T1 Timer / Retry Count makes it possible to optimize the 3174 T1 Timer value and Retry count for a specific customer's network. The T1 Timer is a response timer that identifies the amount of time the 3174 Token-Ring adapter should wait for an acknowledgement prior to retransmitting the Token-Ring frame. The T1 Timer retry number specifies the maximum number of retransmissions that are attempted after the expiration of the T1 Timer. Additional information about the T1 Token Ring Timer can be found in Token Ring Network Architecture (SC30-3374).

5250 Emulation for 3270 CUT-mode devices

5250 Keyboard Emulation support makes it possible for the 3174 to provide IBM 5250 Emulation support for Field Exit, Field Minus and Field Plus. It also provides "5250 Reset Function" emulation. The AS/400 to which the 3174 is attached requires AS/400 V1R3 or later. AS/400 PTF MF02929 is required for V1R3. AS/400 PTF MF02930 is required for V2R1. Later AS/400 Versions and Releases do not require any PTFs.

132 Column Support via AEA

132 Column Support via AEA support allows both ASCII terminal emulation (ASCII terminal emulation for a 3270 device) and 3270 terminal emulation (3270 terminal emulation for an ASCII device) to display up to 132 columns of data on a single line. For example, a user can display extended print lines prior to, or in lieu of, printing.

IBM 3151, 3162, and DEC VT220 devices in 132 column mode support 3270 emulation for 24 rows by 132 columns. It also provides 27 row by 132 column support (Mod 5) support for the 3162, and for the 3151 with a '3151 Cartridge for Expansion'.

Entry Assist Support for ASCII

Entry Assist Support for ASCII devices extends 3174 Entry Assist capabilities offered for 3270 devices to ASCII devices. Entry assist provides tab, word wrap, margin, and audible End of Line (EOL) signal to terminal operators using applications that involve entry and editing of text material. Details on all functions support by the Entry Assist for ASCII are found in the publication GA23-0119.

CSCF IML Password Suppression

IML Password Suppression allows 3174 IML (Initial Microcode Load) from a NetView/CSCF (Central Site Control Facility) console without requiring the entry of a user password. This capability can save keystrokes for the console operator and eliminate the requirement for the console operator to maintain a listing of multiple 3174 passwords and reduces the need for multiple C-list to IML controllers in the network.

Functional Improvements in Configuration Support-C Release 3.0

  • APPN Enhancements
    • 3174 Network Node (NN) compatibility in environments where the host is a LEN (Low Entry Networking) node, APPN EN (End Node), APPN NN, Migration Data Host (MDH), or an Interchange Node (IN).
    • Support for multiple links into a LEN subarea from an APPN network comprised of 3174s or other APPN nodes.
    • Support for the transfer of 3270 and APPN data streams across a single SDLC link between a 3174 and an AS/400.
  • TCP/IP Telnet Support

    TCP/IP Telnet Support provides Telnet client function for the IBM 3174 Establishment Controller. This support allows interactive access to remote TCP/IP hosts/servers from dependent 3174 attached terminals. Control Unit Terminal (CUT), ASCII, and Distributed Function Terminal-Extended (DFT-E) terminals can communicate directly with TCP/IP hosts/servers.

    The 3174 communicates with a TCP/IP host via the 3174's interface to a Token-Ring or Ethernet LAN. Thus, a dependent terminal attached to a 3174 can establish an interactive TELNET session with a TCP/IP server anywhere in the existing LAN network. The host/server may be attached directly to the Token-Ring/Ethernet LAN, or it may exist anywhere in the network reachable via that LAN and any bridges or routers.

    The following TCP/IP protocols are supported:

    • IP - Internet Protocol
    • ICMP - Internet Control Message Protocol
    • ARP - Address Resolution Protocol (Resolver client only)
    • TCP - Transmission Control Protocol
    • UDP - User Datagram Protocol
    • TELNET - Teletypewriter Network (client only)
    • PING - Packet Internet Groper (ICMP)
    • DNS - Domain Name Server (stub resolver)
    • SNMP - Simple Network Management Protocol (MIB-1 Agent Only)

The SNMP agent responds to requests for MIB variable information from an SNMP client elsewhere in the network. The SNMP support requires additional storage, as shown in the Configuration Support-C storage requirements section of this document.

Using 3174 TCP/IP Telnet support, any dependent display that currently attaches to the 3174 controller (CUT, ASCII, DFT-E), can operate in Telnet mode. ASCII displays are supported via the AEA feature (FC 3020). Coaxial attached displays operating in CUT mode are supported as VT100, VT220, IBM 3101 or DG210 devices. These devices are supported as 24 X 80 full-screen devices. When accessing TCP/IP on an IBM host (TCP/IP for VM or MVS) only line-by-line mode is supported. ASCII device screen support is negotiated during the TELNET session set-up. Simple line-by-line mode is the default screen mode.

TCP/IP Telnet Terminal Support

The 3174 attached dependent terminals that can be used to access TCP/IP applications are:

  • Coaxial-attached (CUT) dependent displays (up to 5 sessions via MLT)
  • Intelligent displays operating in CUT mode (up to 5 sessions via MLT)
  • DFT-E displays operating in ASCII host session mode (1 session)
  • ASCII displays (up to 5 sessions via AEA MLT)

TCP/IP Telnet Prerequisites:

  • The 3174 requires a Token-Ring or Ethernet LAN adapter. This adapter is standard on the 13R model.
  • 3174 Model 11R requires an IBM Token-Ring adapter (FC 3026, 3030, or 3044), or an Ethernet LAN adapter (FC 3045).
  • An AEA adapter (FC 3020) is only required when ASCII terminals are to be connected to the 3174. An AEA adapter is not required for 3270 displays utilizing the 3174 TCP/IP Telnet function.

3174 Storage Considerations

TCP/IP Telnet support impacts 3174 control storage requirements. Refer to "Determining Configuration Support-C Control Storage Requirements".

Limitations:

  • TCP/IP Telnet is only supported on 3174s running SNA
  • RPQ 8Q1041 is required for TN3270 support
  • 132-characters-per-line support is not supported under ASCII emulation for CUT terminals in a TELNET session.

This function was previously provided by RPQ 8Q0935.

Other Configuration Support-C Release 3 enhancements include:

  • Concurrent Communication Adapter support for the 3174 Port Expansion Feature

Configuration Support-C Release 3 makes it possible for devices attached to the 3174 via the Port Expansion Feature (FC 3100) to access a secondary host via the Concurrent Communication Adapter. In the past, devices attached to ports 32 to 63 could not access applications running on a secondary host link through the Concurrent Communication Adapter, while devices attached to ports 0 to 31 could access applications running on either the primary, secondary, or both host links. With Configuration Support-C Release 3, devices attached to ports 32 to 63 have the same host link access capabilities as devices attached to ports 0 to 31. A maximum of 160 sessions can be customized for each Concurrent Communication Adapter.

This function was previously provided for Configuration Support-B only via RPQ 8Q0931.

Prerequisites:

  • 3174 Concurrent Communication Adapter (FC #3050, 3051, 3052, or 3053).
  • 3174 3270 Port Expansion Feature (FC #3100)

Limitations:

  • Not compatible with RPQ 8Q0743 - X.25 Token-Ring Gateway

HAP Printer Assignment

Configuration Support-C Release 3 also makes it possible to assign a HAP printer (Host Addressable Printer) to a host other than 1A in a Single Link Multihost (SLMH) environment. The HAP printer may be assigned to any host (1A through 1H) that is accessible via the 3174's primary host link.

The HAP printer must be locally defined to the host. When a 3472 attached printer is used, the 3472 terminal cannot be defined to use a subsystem printer, as the 3174 has no way of knowing a printer is attached to the 3472. One of the other options that defines IBM host access to the 3472 attached printer must be selected. When attached in this manner, the printer ID in the 3472 Operator Information Area (OIA) will be 99 for the 3472 with the attached printer.

HAP Printer Assignment differences from previous HAP support

  • With previous HAP support, a HAP printer could only communicate with the first host on the 3174's primary host link (1A), as defined during 3174 customization. In addition, the HAP printer had to use the second terminal session (1A2), as defined in the 3174's Port Assignment Table (PAST). With Configuration Support-C Release 3, any Single Link Multihost (1A to 1H) can be configured to communicate with a HAP printer. The 3174 will use the last value defined in the logical terminal assignment table as the host to communicate with the attached printer.

Prerequisites:

  • The 3174 must be configured for Multiple Logical Terminal (MLT) support (Q110) and greater than one LT (Q116). The port with the printer assigned must have at least two LTs assigned.

Limitations:

  • HAP printers cannot be assigned to Concurrent Communication Adapter (CCA) host links (e.g., 2A, 3A)
  • Host access to ASCII workstation-attached printers is restricted to the second terminal session (1A2) on the primary host link (1A).

Configuration Support-C Release 3 also adds 3270 terminal support for the following Eastern European languages, keyboard IDs, code pages and character sets:

Configuration Support-C Storage Requirements

Some combinations of the features and functions described in the "Optional Features", the Configuration Support-B, and the Configuration Support-C sections may require additional storage. Before attempting to decide on the total amount of storage required, the level of MLT support should be determined.

MLT Weighting Factors for Configuration Support-C

Each IBM CUT display that is to be supported for MLT sessions requires a certain amount of storage based on the number of sessions desired, the display screen size and screen characteristics. This storage requirement is defined as a "Weighting Factor". The sum of the weighting factor for each terminal on a given 3174 and the physical host link determine the required level of MLT (level 0, 1, 2, 3, 4, 5, 6, 7, 8) to support the required MLT sessions.

MLT sessions on the primary host link are supported via 3174 control storage. MLT sessions via secondary physical host links (i.e. CCA), are supported by internal CCA feature storage. CCA feature storage is not expandable. Each CCA feature supports a maximum of MLT level 2. If LAN Gateway is customized on the CCA, the total presentation space (PS) on the CCA is 256KB.

The tables below should be used to determine the MLT requirements for the primary host link when multihost support is NOT selected and for the primary host link when multihost support IS selected.

Notes:

  1. Use Table A if NO multihost support (Concurrent Communication Adapter and/or Single Link Multihost Support) is being customized.
  2. Use Table B if multihost support (Concurrent Communication Adapter and/or Single Link Multihost Support) IS being customized. Be sure to sum the weighting factors for the primary and any secondary physical host links (i.e. CCA), when present, separately. The primary host link MLT level is used when determining 3174 control storage requirements. Secondary host link MLT level requirements must be reviewed to ensure they are not greater than MLT Level 2.

Note: EAB (Extended Attribute Buffer) refers to the ability of some displays to allow extended highlighting (reverse video, blinking and underscore), extended color (seven colors), Programmed Symbols, etc.

Note: If you are planning storage for ASCII Tektronix 4205s or UDT tables for which transparency is being defined, you must add additional storage. Base the additional storage amounts on screen size. If the display is 24 X 80, add 2 KB more storage; if the display is 30 X 80, add 4 KB more storage. If you are planning for only one session on an ASCII display, no additional storage is required

Note: Some CUT displays support a number of screen sizes and allow the user to select a screen size as part of display set-up mode. If these displays support the Extended Function feature, then the largest screen size supported by the device must be used to determine its weighting factor. If the display does not support this feature, then the screen size chosen during set-up mode should be used.

For Configuration Support-B, Release 4 or Configuration Support-C, 3270 devices with Extended Function Feature (Feature 6) can support different screen sizes. Refer to question 110 in Chapter 6 of the 3174 Planning Guide (GA27-3862 for CS-B and GA27-3918 for CS-C).

Note: If CCAs are installed, do not count MLT sessions assigned to the secondary physical host links (i.e., CCA) when determining the weighting factors for 3174 control storage. Be sure, however, to confirm that each secondary host link (i.e., CCA) requirement does not exceed MLT Level 2. If LAN Gateway is customized on the CCA, the total presentation space (PS) on the CCA is 256KB.

Buffered Local Copy Print Weighting Factor for Configuration Support-C

To calculate the weighting factor for the Buffered Local Copy Print function, determine the average number of copies you want to allow in the printer queue. Then multiply by the buffer size in the following table:

 CUT or ASCII Device Screen Size       Buffer Size (K)
------------------------------- ---------------
CUT/24X80 2
CUT/24X80 with EAB 4
ASCII/24X80 2
ASCII/30X80 4
ASCII/32X80 4
ASCII/43X80 4
ASCII/24X132 4
ASCII/27X132 4
CUT/32X80 4
CUT/43X80 4
CUT/27X132 4
CUT/32X80 with EAB 8
CUT/43X80 with EAB 8
CUT/27X132 with EAB 8


For example, if you want the potential to have three copies in the printer queue and use a CUT/43X80 with EAB, you would need 24K (3 x 8K).

Copy Session to Session weighting factor for Configuration Support-C

To calculate the weighting factor for Copy Session to Session, multiply the number of configured ports by 4K. For example, a controller with 16 configured ports requires 64K of storage (16 x 4K).

Split Screen

If you expect to use split screen functions while accessing TELNET sessions, add 2K for each non-EAB TELNET LT and 4K for each EAB TELNET LT to your base MLT calculation.

MLT Levels for Configuration Support-C

Based upon the sum of the weighting factors selected in table A or B, the Buffered Local Copy Print weighting factor, and the Copy Session to Session weighting factor, determine the appropriate MLT Level required:

  • For MLT level 0, the sum of weighting factors is 0.
  • For MLT level 1, the sum of weighting factors must not exceed 64.
  • For MLT level 2, the sum of weighting factors must not exceed 128.
  • For MLT level 3, the sum of weighting factors must not exceed 512.
  • For MLT level 4, the sum of weighting factors must not exceed 896.
  • For MLT level 5, the sum of weighting factors must not exceed 1152.
  • For MLT level 6, the sum of weighting factors must not exceed 1536.
  • For MLT level 7, the sum of weighting factors must not exceed 2048.
  • For MLT level 8, the sum of weighting factors must not exceed 2688.

Determining Configuration Support-C Control Storage Requirements

Any one of the feature/function combinations listed in Tables 1, 2 and 3 is operable within its listed storage requirement. (Feature/functions not shown in the tables, do not increase 3174 control storage requirements.)

The following tables can be used to determine the amount of storage required for the combination of features and functions desired.

  1. Using TABLE 1, add the storage weighting factors for all desired functions to the base control storage weight (2050).
  2. If Gateway support is required, used Table 2 to determine the additional storage requirement based on the host links (primary or CCA) that will be used.
  3. If APPN support is required, see TABLE 3 to determine the additional storage for the level of APPN support required.
  4. Using the above total, refer to TABLE 4 determine the total 3174 control storage required.

(A) For an ISDN only Gateway, the 28 DSPU limit in 512KB storage on the
Primary Only is increased to a 32 DSPU limit.
(B) Token-Ring Network Gateway only.
Note - If you are planning to attach a large number of DSPUs to
a 3174 LAN Gateway controller (Token-Ring or Ethernet), thruput for
locally attached terminals may not be acceptable (e.g. poor response
times, decreased data transfer rates, or status code 379-02 is
displayed). Please consult the 3174 Performance Guidelines on HONE
to evaluate the 3174 performance and capacity factors that can be
expected in your desired configuration and application/host
environment.


To use Table 2, proceed as follows:

  1. Select whether the primary interface is channel or remote attached. If channel attached, determine if the maximum RU size is 4KB. Select the appropriate section of the table based on the maximum RU size supported.
  2. Determine the number of Downstream Physical Units that will be connected through the primary host link, if any.
  3. Determine the number of Downstream Physical Units that will be connected through the CCA links, if any. NOTE: There is a maximum of 50 DSPUs per CCA link.
  4. Using these two numbers, locate the specific storage increment that will support this configuration. This is the additional storage needed. NOTE: The maximum number of DSPUs connected through the 3174 Gateway with the Type 3 adapter is 140. The maximum DSPUs for the Type 3A adapter is 250 for 4KB RUs. 8KB RUs support a maximum of 100 DSPUs.

As examples:

  1. Assume: Local gateway, 4KB RUs, with 64 primary PUs, and 30 CCA PUs, then the additional amount of storage required for this gateway function is 1536KB.
  2. Assume: Local gateway, 8KB RUs, with 64 primary PUs, and 30 CCA PUs, then the additional amount of storage required for this gateway function is 2048KB.

Note: The maximum storage available when using Configuration Support-C is 6.0MB. If you customize for items requiring more than 6.0MB of storage, a deconfiguration to a minimum will occur during IML.

Note: A minimum of 4.0MB of control storage is recommended when using the off line Central Site Customization Utility (CSCU), Generate Control Diskette procedure, to generate control diskettes. This will reduce the time and manual intervention required for control diskette generation.
