IBM 3174 Introduction

Some of the external IBM modems that can be used in remote systems are:
Nonswitched Network Modems
• 3833
• 3834
• 3863 Model 1
• 3864 Model 1
• 3865
• 3868 Model 1
• 3868 Model 2
• 3868 Model 3
• 3868 Model 4
• 5811
• 5865
• 5866
• 5868
• 5868
• 5979 Model L41

Switched Network Modems
• 3863 Model 2
• 3864 Model 2
2400 bps
4800 bps.
Some of the external IBM modems that support switched network backup (SNBU)
operation are:
• 3863,3864, and 3865
• 5865 and 5866 (5866 exception is 3276).
A backup
Control diskette configured for SNBU may be needed.
Switched
network backup operation is initiated by the terminal operator. For
example, when a problem is experienced
with a nonswitched line, the operator can
invoke
SNBU by calling the host system via the public switched telephone network
to reestablish a connection and resume operation.
The
X.21 Interface permits SDLC operation at speeds of 2400, 4800, 9600 or
48 000 bps through X.21 switched and nonswitched data communication equipment.
The X.25 interface enables remote models to attach to host systems
via an X.25
network, using SNA-defined protocols.
