The 3174 Model 11R is a floor-standing remote controller that supports the EIA 232D/CCITT V.24/V.28 or CCITT V.35 interfaces for SDLC, BSC, or X.25 remote link attachment. The Model 11R supports up to sixty-four 3270 devices and twenty-four ASCII devices.

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 Model 11L, 11R, 12L, 12R, 13R, and 14R.

• Any combination of up to eight 8 port multiplexers (3299 Model 002 and 003) and Terminal Multiplexer Adapter optional features (#3103).
• One 32 port multiplexer (3299-032, 3299-32T, or feature #3105) and any combination of up to four 8 port multiplexer (3299 Model 002 and 003) and Terminal Multiplexer Adapter optional feature (#3103)s.
• Any combination of up to two 32 port multiplexers (3299-032, 3299-32T, or feature #3105).
