Appl. No.:

09/396964

Assignee:

ADC Telecommunications, Inc. - Eden Prairie MN

International Classification:

H04H 100

US Classification:

455 305, 455561, 725143

Abstract:

A method for initializing a service unit in a communication system. The method includes receiving a synchronization signal from a head end at the remote unit. Further, an identifier is received specifying the remote unit. The method further receives an upstream frequency band and control channel designation at the remote unit, wherein the frequency band includes a number of subbands with at least one control channel in each subband. The method tunes to the designated frequency band and a reference signal is transmitted on a selected channel to the head end. The method receives 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. The method adjusts parameters at the remote unit based on the adjustment signals.

US Classification:

455 7, 370342, 370474, 37921201

Abstract:

A scanning method for establishing communication between a head end and a plurality of remote units in a multi-point to point communication system is described. The method includes 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 the 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. The method further includes scanning, at each of the 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 remote units to identify a particular region of the plurality of regions that each of the remote units is to use for receiving information from the head end.
