ABSTRACT:
A digital transmission system in which bursts of digital signals are transmitted in opposite directions over a two wire telephone loop at fixed frame intervals. Each signal burst is bounded by initial and final synchronization bits at its beginning and ending respectively. Once frame synchronization is established the signals are only gated to the receiver during a window interval which is coextensive with that of the received bursts.
