ABSTRACT:
A broadband communications system for coupling telephony or other digital networks to a CATV network. The system transmits a multiplex of telephony signals in the forward band of the CATV network. The forward telephony channels are demodulated and demultiplexed by a plurality of subscriber terminals into the individual telephony signals directed to an addressed subscriber. Signals returning from subscribers are digitized into standard telephony signals onto the reverse band of the CATV network, and demodulated and multiplexed into a standard telephony signal that is interfaced to the telephony network. A multiplicity of subscribers are initially assigned to a selected reverse band channel. If more than one subscriber contends for use of the reverse channel by transmitting in the channel, signals from the contending subscribers interfere and prevent any subscriber's identity from being decoded and acknowledged. The contending subscribers wait for a random wait time and re-attempt to transmit. Upon transmission re-attempt, one of the subscribers (typically the one with the shortest wait time) will successfully gain access to the reverse channel, and the other subscribers are assigned to a different reverse channel.
