Abstract
A repeater is provided for use in a communications network which includes a plurality of transceivers, the repeater being bidirectional and allowing the interconnection of two segments of the network and also allowing longer communications networks to be used by matching or amplifying the signal level of an incoming information packet on one segment and coupling the matched or amplified signal to a succeeding segment. The repeater has two ports that preferably utilize two semiconductor chips, each port having a carrier one-shot which detects the presence of an information packet arriving at that port. If an incoming port's one-shot is triggered by an incoming packet of information, the carrier one-shot for the repeating port and the incoming port transmitter are disabled. If the transceiver coupled to the repeating port detects a collision, this information is fed back to the incoming port which enables the incoming port transmitter thereby causing a collision on the incoming network segment which causes the termination of the transmission of the data packet by a using device already transmitting.
