Abstract
A method for initializing a service unit in a communication system is provided. The method comprises receiving a synchronization signal from a head end at the remote unit, receiving an identifier specifying the remote unit and receiving an upstream frequency band and control channel designation at the remote unit. The frequency band includes a number of subbands with at least one control channel in each subband. The method further comprises tuning to the designated frequency band, transmitting a reference signal on a selected channel to the head end, receiving adjustment signals based on the reference signal transmitted to the head end to allow signals transmitted from the remote unit to be orthogonal at the head end to signals from at least one other remote unit and adjusting parameters at the remote unit based on the adjustment signals.
