CS 1000 considerations

A survivable remote gateway (SRG) extends CS 1000 features from the main office and provides a
business continuity solution to one or more remote SRG locations (branch offices). The SRG50
Release 1.0 operates with CS 1000 running Release 4.5 and is backward compatible to Release 3.0
and Release 4.0. The SRG50 does not operate with CSE 1000 Release 1.0 and Succession 1000 2.0
systems. The SRG50 is optimized for a branch office or remote site with a requirement for 5-to-32
survivable IP users.
The Nortel Communication Server 1000 Main Office configuration for Survivable Remote
Gateway 50 guide provides information specific to the configuration of an SRG50 on the CS 1000.
This guide is included on the SRG50 documentation CD for your reference. Access to other
CS 1000 documentation may be required if personnel are not familiar with configuration of branch
offices on the CS 1000. The Nortel Communication Server 1000 Main Office configuration for
Survivable Remote Gateway 50 guide provides contextual references to these other documents.
This following activities are specific to SRG50 configuration when the main office call server is a
