Abstract:
A method of establishing communication between a head end and a plurality of remote units in a multi-point to point communication system, comprising:transmitting information from the head end to the plurality of remote units in a plurality of regions of a first frequency bandwidth, each of the regions having at least one control channel associated therewith, identification information corresponding to each of n remote units of the plurality of remote units being periodically transmitted from the head end on the at least one control channel of one of the plurality of regions of the first frequency bandwidth during a first predetermined time period, the identification information for each of the plurality of n remote units being transmitted out of phase with respect to the identification information for the other n remote units; andscanning, at each of the n remote units, the at least one control channel of each of the plurality of regions in the first frequency bandwidth to detect identification information corresponding to each of the n remote units to identify a particular region of the plurality of regions that each of the n remote units is to use for receiving information from the head end.
