Abstract
A hybrid amplifier and regenerator (HAR) device is designed for use in a communications network for carrying downstream traffic in a forward frequency band and for carrying upstream traffic in a reverse frequency band spaced from the forward frequency band and below the forward frequency band. The hybrid amplifier and regenerator (HAR) device comprises an analog amplifier for amplifying the downstream traffic and a digital regenerator. The digital regenerator comprises mapping circuitry for mapping digital upstream traffic carried in at least one ramp band which is part of the reverse frequency band to digital upstream traffic carried in at least one express band which is also part of the reverse frequency band but spaced from the at least one ramp band, and an express band transmitter for transmitting digital upstream traffic from the mapping circuitry in the at least one express band.
