Overview
This manual describes the Verilink Automatic Protection Switch
(APS 2000), a fully automatic, 1 for n, T1 protection switch
component of the Verilink Access System 2000 (AS2000) product
family.
Purpose and Use
The APS 2000 system automatically senses degrading or failed T1
lines and restores service to a protection line.
When the trouble clears, the system returns service to the original
working line, either automatically or manually. The protection line
can carry low priority traffic which will be bumped if another T1
fails.
Alarms and control are provided both locally and remotely via
SNMP or Telnet. APS 2000 consists of a software addition to
Verilink’s T1 Access Cards (TACs) and software enhancements to
the Verilink SNMP MIB.
