ABSTRACT:
A time-division multiplexing synchronization mechanism employs a 1-bit/frame framing channel with a pattern that repeats every 2 frames. Acquisition and reacquisition of synchronization with such a framing pattern is enabled through the use of an explicit synchronization procedure. With this procedure, initial acquisition of frame synchronization as well as reframing after loss of synchronization are carried out while the transmission channel is carrying only a predefined bit pattern. When the receivers are in synchronization, synchronization is monitored and maintained using a 1-bit/frame framing channel, while the communications link is carrying multiplexed bit streams with the appropriate format.
