Abstract
An improved transmitter/receiver for use on a common cable communications system which permits sending and receiving of data at multiple data rates. Each transmitter first transmits a message alerting the intended receiver. The message also informs the receiver of the rate at which data is to be transmitted. This data rate is a function of the available bandwidth between the transmitting transmitter and receiving receiver. Each transmitter includes a memory of such bandwidth for all receivers on the cable.
