Abstract
If each data channel comprising a set of multiplexed data channels contains channel identity information, a single framing detector operating on one channel can provide a framing detection operation regardless of where the search is commenced thereby avoiding a search of all of the channels to obtain framing information. By having unique tag or identity bits incorporated in each of the multiplexed data channels, the timing problems for obtaining synchronized parallel output bits from each of the channels can be logically ascertained and the channels can be rerouted and individual channels of the rerouted channels can be time delayed to obtain the time synchronization.
