Abstract:
1. An apparatus for preventing loss of service in network comprising: a plurality of receivers, each receiver being capable of receiving signals according to predetermined communication protocols from a plurality of modems; a switching unit which selectively connects a spare receiver to a signal line associated with one of the plurality of receivers, enabling the spare receiver to receive signals sent to a selected one of the plurality of receivers from a modem associated with the selected one of the plurality of receivers; and a controller configured to instruct the switching unit to connect the spare receiver to a communication line of a troubled receiver of the plurality of receivers in response to a beginning of a mass modem deregistration event for modems registered with the troubled receiver, and configured to configure the spare receiver to communicate with modems associated with the troubled receiver by sending a communication request signal to one or more modems associated with the troubled receiver, wherein the sending is performed after the configuration of the spare receiver to communicate with modems associated with the troubled receiver, in response to the determination of the mass modem deregistration event, and wherein the beginning of a mass modem registration event is determined to have occurred by the controller when a number of modems associated with the troubled receiver that de-register within a specified time period exceeds a specified threshold.
