Survivability
This chapter provides a brief overview of the Small System's Survivability
feature. It also describes the procedures to configure Survivability on a new
system, or add the capability to an existing Small System.
The following are the two modes of operation:
• Survivability is the ability of a Small System's IP expansion cabinet or
chassis to perform Call Processing, for its local resources, when it is no
longer connected to the main cabinet or chassis. This is referred to as
survival mode.
• Normal mode is when the local resources of an IP expansion cabinet or
chassis are controlled by the Call Processing of the main cabinet or
chassis.
Survivability is available for any IP expansion cabinet or chassis with
Succession 3.0 Software.
