2. CPX-1000 Voice Services Platform Description
The CPX supports redundant CP modules (
Figure 2–7
).
Figure 2–7. Call Processor Redundancy
On power up, the primary CP
(in the lower numbered slot
— slot 7) is the active CP and the secondary CP (in the
higher numbered slot — slot 9) is the standby CP.
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.
