Abstract
A time compression multiplex digital transmission system having an improved frame synchronization circuit in which a limited window is gated open at a master station to search for the final synchronization bit of the incoming burst signal from a slave station. Thereafter the window is expanded to open just prior to the anticipated arrival of the initial synchronization bit of the following burst. Once the presence of this initial synchronization bit is confirmed frame synchronization of the incoming burst signal is established and the window is then gated substantially coextensively with that incoming signal.
