ABSTRACT:
A method of operating a communication station having two sets of paired input and output terminals which are normally coupled to respective paired sets of terminals in two other stations to form a network includes the steps of: monitoring the input terminal of one set of terminals in the station to detect an idle signal, a delimiter signal, or silence thereon; transmitting the idle signal on the output terminal of the one set if silence is detected by the monitoring step; sending the delimiter signal on the output terminal of the one set if the idle signal is detected by the monitoring step; and coupling internally in the station the input terminal of the one set to an output terminal of the station in a predetermined fashion to permit signals on the input terminal of the one set to pass through the station if the delimiter signal is detected on the input terminal by the monitoring step.
