IBM 3174 Introduction

3174 Model 52R
directly or sixteen 3270 terminals and eight ASCII terminals through one or two
IBM 3299 Terminal Multiplexers.
Customizing
is performed with a control unit terminal attached to port 0 of the 3174.
Any terminal can be attached to port 0 at other times. The Model 61 R supports full
keyboard utilities.
Subsystem
online tests and problem determination are performed through a
control
unit terminal attached to any port or multiplexer without interrupting other
terminals attached to the 3174. Offline tests are performed through the 3174
control panel.
The
customer can install the following features:
Second diskette
drive
Token-Ring Network Gateway feature
Asynchronous Emulation Adapter
Type 3A Communication Adapter
Storage Expansion
20MB Fixed Disk Drive
Concurrent Communication Adapter.
The 3174 Model 52R is a
medium-cluster controller designed for remote
operations.
It contains a Type 2 Communication Adapter providing X.21 interfac~
(CCITT V.11) for SNA/SDLC or X.25 remote link attachment. It has 512KB of base
storage and one 5-1/4-inch, 1.2MB, high-capacity diskette drive. If the controller
has one diskette drive and uses devices that require downstream load microcode,
a second diskette
drive or fixed disk must be installed. A nine-port terminal
adapter supports nine terminals directly or sixteen 3270 terminals and eight ASCII
terminals through one or two IBM 3299 Terminal Multiplexers.
