1-4 SSR-600 Installation Guide

1.3 OPTIONAL FEATURES

Rack Mounting Capabilities - The SSR-600 can be installed in a

19-inch rack with the optional mounting brackets and screws (Cabletron

part number SSR-600-RCK-KIT). Refer to Chapter 3 for complete rack

mounting instructions.

SSR-600-ECM Auxiliary Card - Designed to authenticate, encrypt,

generate public keys and/or compress data packets stored in the host

platform’s shared memory, the SSR-600-ECM will also decrypt and

expand packets that have been encrypted and compressed.

This optional hardware data compression/encryption module accelerates

data compression for the SSR-600 over Nailed-up PPP, or ISDN and

Frame Relay with PPP riding underneath them. Depending on the packet

type and size, hardware data compression provides data compression for

enhanced throughput on each T-1 SWPIM interface. To use the hardware

data compression module, compatible equipment such as another

SSR-600, or other vendors equipment which conforms to the applicable

standards, must be in use at both ends of the WAN link. When the

hardware data compression module is installed on the board, it

automatically assumes the compression task from software. There is no

conﬁguration necessary to prioritize hardware over software compression.

SWPIMs - The SWPIMs are the interface for the WAN connections for

the SSR-600. Available as listed in the Release Notes. Refer to

Section 1.1.1 for details.
