Figure 2–7. Call Processor Redundancy

￿The active CP module handles all call processing activity, ￿maintains all signaling, manages all IADs, captures statistics and alarms, and monitors all hardware in the system. It

passes all this information to the management system.

The standby CP module mirrors the state information of ￿the active CP module (i.e., all of the activity on the active CP

module) and can take over at any time.
