IBM 3174 Introduction

Token-Ring Network Attachment
The controllers attached to an IBM Token-Ring Network can communicate with the
host by means of a gateway feature that attaches the Token-Ring Network to the
host. For the
following controllers, this gateway may be an IBM 16/4Mbps
Token-Ring Network Gateway feature:
• Models 1L, 11L, 1R, 11R, 2R, 12R, 51R, 61R, 52R, and 62R.
The following controllers attach the workstations to the IBM Token-Ring Network:
• Models 3R, 13R, 53R, and 63R.
Communication Networks and Modems
When using BSe protocol, the following controllers can attach to a multipoint
nonswitched network:
• Models 1 R, 11 R, 51 R, 61 R, 81 R, and 91 R.
When using SOLe protocol, the following controllers can attach to a multipoint
non-switched line network:
• Models 1 R, 11 R, 2R, 12R, 51 R, 61 R, 81 R, 91 R,82R, and 92R.
The following can also attach to switched lines:
• Models
1R, 11R, 2R, 12R, 51R, 61R, 81R, 91R, 82R, and 92R.
When two or more SOLe devices are multidropped, messages can be
simultaneously transmitted and received using duplex facilities (multi-multipoint
operation). The 3174 controller can operate in data duplex mode.
