Abstract:
A method in a cable modern (CM) to adjust its timing offset when waking up prior to the termination of its sleep cycle is provided. The method includes the step of receiving a service identifier (SID) for a multicast maintenance region, receiving a message from a cable modem termination system (CMTS) to enter a sleep cycle, waking up from the sleep cycle before the end of the sleep cycle in response to an event, and sending a message to the cable modem termination system (CMTS) to adjust the CM's timing offset during the multicast maintenance region.
