Abstract
A spare receiver in a CMTS is used to prevent loss of service to subscribers during a failure of a receiver. The beginning of a mass modem de-registration event is detected by the operator or automatically by the CMTS. Upon detection of the beginning of the mass modem de-registration event, the spare receiver matrices to the troubled receiver and is configured according the communication parameters of the troubled receiver. The spare receiver sends communications to one or modems normally registered with the troubled receiver to determine if the mass de-registration event is the result of a failed receiver or a connection problem. In the event of a failed receiver, the spare receiver stays matriced with the troubled receiver and passes communications to/from from modems normally registered with it. The cable operator may swap out the troubled receiver and repair the system without significant loss of service to the subscribers.
