Abstract

Disclosed is a communications network for peripherals in a digital loop carrier transmission system. A broadcast STAR network is employed so that all peripherals receive any message which is broadcast by any of the peripherals. No peripheral broadcasts without clearance from the active communications hub. Two hubs can be provided to alternatively act as the active hub. Each peripheral includes a controller which transmits a request to send signal, multiplexes the request to send signal with an outgoing message, receives clear to send signals, and demultiplexes the clear to send signals from an incoming message.
