Paradyne CPX-1000 manual Voice/Data Interruptionœ possible

Administrative switchover—the network administrator initiates a CP switchover using JetCraft or JetVision. A forced switchover always goes through regardless of voice traffic and active cells remain up.

This architecture enables two types of CP module switchovers:

￿	Automatic switchover—the system detects a problem
	with the active CP module and performs a forced
	switchover to the standby CP module. Mechanisms used to
	detect problems with a CP module include:
	— Loss of a CP-to-MP (Management Processor) module
	heartbeat
	— Loss of a CP-to-CP module heartbeat
	— Failure of a CP to respond to an “are you alive” ping
	request from the High Availability software
	— Failure of the High Availability software to detect a ping
	request from the ping component on a CP module

Voice/Data￿ Interruptionœ – possible

Calls that are in setup process are lost during a forced switchover. Calls that are already established and carrying voice traffic continue during a switchover.

Upon initiating a switchover, the previously active CP’s calls are assumed by the new active CP. After the switchover, the old active CP assumes the standby role (if all is well). CP switchovers do not automatically revert back.
