Operation and Maintenance

Under normal conditions, the primary (active) signaling controller application (which includes MTP3 and the Call Processing Engine) processes calls. In addition to normal call processing, in a fault-tolerant configuration the primary signaling controller updates the standby signaling controller with call state information when a call enters the establish phase (an answer message has been received). This ensures that the call state is maintained in case of failure.

The following are normal operating procedures for the signaling controller:

Managing signaling channels and lines
Managing traffic channels
Managing switchover

The following are operating procedures under various equipment failure scenarios:

Signaling link termination failure
Signaling controller failure
Operating system failure
LAN switch failure

The following are maintenance tasks necessary for each component in your Cisco SC2200:

Checking equipment status
Preventive maintenance
Removing the component from your system
Replacing the component

For detailed instructions on these operation procedures and maintenance tasks, see the Cisco Media Gateway Controller Release 7 Operations, Maintenance, and Troubleshooting Guide.

Configuring Other Components

Refer to the documentation that shipped with a particular component for configuration information.
