A method for synchronizing timing of signal transmissions in a telecommunication system (100) determines a "fixed portion" (222) of the propagation delay between the central unit (102) and subscribers (206, 208) in a particular node (202).

A method for synchronizing timing of signal transmissions in a telecommunication system (100) determines a "fixed portion" (222) of the propagation delay between the central unit (102) and subscribers (206, 208) in a particular node (202). Additionally, the method determines a `variable portion` (226) of the propagation delay that accounts for the variation of spacing of different subscribers (e.g., homes (206, 208)) on a particular node (202). The preferred method offsets the control unit's (102) receiving window (410) in accordance with the fixed portion, and directs the various subscriber units (206, 208) to offset the timing of signals (314, 322) (i.e., bursts of data) that they transmit by the variable portion (226).

[ We claim:] [1.] A method for synchronizing timing of components of a telecommunication system comprising the steps of:receiving, at a subscriber equipment, a signal indicative of a receiving window of a control unit that routes information provided by the subscriber equipment;in response to the step of receiving, transmitting, from the subscriber equipment to the control unit, a signal burst which is sampled at the control unit during the receiving window, the receiving window being adjusted in time by a fixed portion of a propagation delay from the subscriber equipment to the control unit;receiving, at the subscriber equipment, time alignment information indicative of a variable portion of the propagation delay from the subscriber equipment to the control unit calculated from a timing of arrival of the signal burst at the control unit; andtransmitting, from the subscriber equipment, an information burst positioned in time in accordance with the time alignment information.
