xvi ATM 25 Mbps Module: Installation and User's Guide

Chapter 1. Overview
This chapter presents an overview of the ATM 25 Mbps Concentration Module (A12-TP25 module). It
describes the main functions of the module, and how the module operates as part of the ATM subsystem
when installed in the IBM 8260 Nways Multiprotocol Switching Hub or IBM 8285 Nways ATM Workgroup
Switch Expansion Unit.
 Copyright IBM Corp. 1996 1

A12-TP25 Module in the 8260 Hub or 8285 ATM Workgroup Switch
The A12-TP25 module is a single-slot module that functions as part of the IBM 8260 Nways Multiprotocol
Switching Hub or IBM 8285 Nways ATM Workgroup Switch Expansion Unit.
A12-TP25 modules can be used in any of the following ways:
To send and receive data from an ATM subsystem in another ATM 8260 hub or 8285 workgroup
switch.
To attach high capacity workstations and servers that function in ATM mode.
A12-TP25 modules interface to the 8260 hub or 8285 workgroup switch by means of the Control Point
located in either the A-CPSW module or 8285 base unit. A12-TP25 modules process ATM cells of data
by:
Checking their validity
Accessing the switching tables to locate the destination module
Preparing the internal ATM format required by the Control Point
Sending the cells to the Control Point.
A12-TP25 modules can be used in any vacant slot in the 8285 workgroup switch expansion unit, or any
vacant slot in the 8260 hub except for slots 9, 10, and (for 17-slot models) 11 and 12. These slots are
reserved for A-CPSW modules. In 17-slot 8260 models, although slot 12 is also reserved, you can insert
an A12-TP25 module in slot 12 if no A-CPSW module is installed in slot 11.
Like other ATM media modules, such as the A4-FB100 module, the A12-TP25 module can be inserted
while the hub or workgroup switch is operating without disturbing data traffic on other modules. Before
removing the module however, you must first isolate it by using the SET MODULE command.
For more information on how to install and change modules, see the
IBM 8260 Multiprotocol Switching
Hub Installation Guide , SA33-0251 or IBM 8285 Nways ATM Workgroup Switch Installation and User's
Guide SA33-0381, as appropriate.
