Abstract

A bandwidth management system for a remote repeater network for modifying a first signal to create a second signal within the bandwidth of a communications link, transferring the second signal across the communications link, and reconstructing the first signal at the remote end of the communications link. The bandwidth management system featuring several mixing modes for performing the signal conversion and reconstruction. The system offering a calibration feature to correct for phase distortions introduced in reconstruction of the original signal. The calibration feature incorporating signals from a global positioning satellite system for reconstruction.
