Overview

The 9A656-04 (shown in Figure 1-1) is a 4.5 Gbps, single slot module for the

SmartSwitch 9500 chassis. Up to four ATM Network Interface Modules (ANIMs)

of any type can be plugged into the 9A656-04 to provide front panel connectivity

to the network. Cabletron Systems ANIMs can support up to 622 Mbps of

bandwidth per port. The 9A656-04 switches data between the ANIMs and the Cell

Transfer Matrix (CTM) backplane in the SmartSwitch 9500 chassis. This allows for

high-speed switching of data between modules installed in the same chassis that

connect to the CTM backplane. The CTM provides a dedicated 1.6 Gbps link

between each 9A656-04 module.

Through its distributed switching architecture, the 9A656-04 allows all the

modules in the chassis to appear as a single entity, with a single IP address and a

single ATM address. The individual i960 processors and the CTM backplane

interfaces are transparent to the network manager and management applications.

A fully loaded SmartSwitch 9500 chassis appears as a single switch, with one IP

address, and one ATM address.

The 9A656-04 is fully compatible with the following ATM Forum speciÞcations:

¥ Integrated Local Management Interface (ILMI) 4.0 for autoconÞguration.

¥ UNI v3.0 /3.1 and v4.0 for signalling.

¥ ATM Forum P-NNI 1.0 and IISP 3.0/3.1 routing speciÞcations for establishing

connections between ATM switches.

¥ IETF AToM MIB (RFC 1695) and AToM II MIB.

¥ LANE 1.0 for the management LAN Emulation Client.
