Abstract
A communication system is described. The communication system includes a distribution network and a head end terminal adapted to transmit downstream control data and downstream telephony information in a first frequency bandwidth over the distribution network and adapted to receive upstream telephony information and upstream control data in a second frequency bandwidth over the distribution network. In addition the communication system includes a plurality of service units, each service unit operatively connected to the distribution network for upstream transmission of upstream telephony information and upstream control data in the second frequency bandwidth and for receipt of downstream control data and downstream telephony information in the first frequency bandwidth. The head end terminal includes a detector that detects at least one local transmission characteristic of a service unit and generates an adjustment command as a function of the detected at least one local transmission characteristic for transmittal. Each service unit adjusts the at least one local transmission characteristic when an adjustment command is received from the head end terminal in the downstream control …
