IBM 3174 Introduction

3174 Model91R
3174 Model 82R
The 3174 Model 91 R is a small-cluster controller designed for remote operations. It
contains a Type 1 Communication Adapter that provides EIA 232D/CCITI V.24 and
CCITT V.35 interfaces for SNA/SDLC, BSC, or X.25 remote link attachment. It has
2MB of base storage and one 5-1/4-inch, 2.4MB, high
.. capacity diskette drive. A
four-port
terminal adapter supports four terminals directly or eight 3270 terminals
through an IBM 3299 Terminal Multiplexer.
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 91 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
91 R controller supports no customer-installable features.
The 3174 Model 82R is a
small-cluster controller designed for remote operations. It
contains a Type 2 Communication Adapter that provides an X.21 interface (CCITI
V.11) for SNA/SDLC or X.25 remote link attachment. It has 1 MB of base storage
and one 5-1/4-inch, 1.2MB, high-capacity diskette drive. A four-port
terminal
adapter supports four terminals directly or eight 3270 terminals through 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 82R 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.
This model of the 3174
controller does not support any customer-installable
features.
