1. A Low Duty Cycle (LDC) controller for use in a communications network, comprising:
- a processor programmed to;
formulate synchronization information to maintain synchronization between the LDC controller and a plurality of terminals in the communications network, wherein the synchronization information is maintained separately and does not rely on protocols and timing associated with the communications network; and
,a transmitter configured to transmit the synchronization information on a half-duplex forward link channel of the communications network to at least one of the plurality of terminals.

Abstract
Operating at least one low duty cycle (LDC) controller to maintain synchronization between the LDC controller and a plurality of LDC terminals operating over a communication network using only overhead channels of the network and conforming to the protocol and timing of said network, wherein synchronization between the LDC controller and the plurality of LDC terminals is maintained separately from the protocol and timing of the communication network, and enables the LDC controller to schedule power down and wake up of the plurality of LDC terminals for durations longer than allowable under the protocol and timing of the communication network.
