Digital repeater for data signals over a tree and branch network

摘要

A digital repeater for use in a tree and branch communication network is disclosed. The digital repeater has first path for downstream data communications. The first path does not perform Viterbi decoding in order to minimize the delay for downstream communications. A second path with a Viterbi decoder is used to detect communications addressed to the digital repeater. The disclosure includes other related material including teachings on the integration of the digital repeater into a network including modifications to polling, discovery, and automatic gain control procedures.
