1. A modem for a wireless network having a base station configured to communicate with a bandwidth manager via the modem, wherein the bandwidth manager is configured to allocate wireless bandwidth to the base station, the modem comprising:
a first transceiver configured to receive heartbeat messages from the base station;
a second transceiver configured to transmit the heartbeat messages to the bandwidth manager;
a memory; and
a processor configured to control the operations of the first and second transceivers and store and retrieve a copy of a heartbeat message in the memory, wherein:
the processor is configured to maintain a long timer and a short timer for the base station such that:
the processor is configured to re-start the long and short timers and cause the second transceiver to transmit the heartbeat message to the bandwidth manager, upon the first transceiver receiving a heartbeat message from the base station;
the processor is configured to re-start the short timer and cause the second transceiver to transmit a copy of the stored heartbeat message to the bandwidth manager, upon the short timer expiring; and
the processor is configured to stop causing the second transceiver to transmit a copy of the stored heartbeat message to the bandwidth manager, upon the long timer expiring.
