ABSTRACT: This document provides the Telcordia view of the architecture and design of a residential gateway, with a strong emphasis on structure and functionality. Gateways solve new problems now being experienced with distributing digital signals within the home, which may require format translation at the point of entry, as well as blocking ingress of noise generated inside the home. The distribution problem exists for all access platforms, and the ingress problem exists for Hybrid Fiber Coax, and possibly for the analog overlay common to most "switched digital video" installations. The gateway also permits smooth integration of signals delivered via several access technologies, such as coax, fiber, twisted pair, and wireless.
