Abstract:
A method of aligning a plurality of data streams, each data stream comprising a series of cells, each cell comprising a data portion and an error check sequence (ECS), said method comprising the steps of:synchronizing on each data stream independently by determining the start and end of each cell in accordance with its length, and generating a synchronization pulse upon the detection of the ECS in each cell; generating a hold signal upon the generation of a synchronization pulse produced in response to the last of said plurality of data streams to achieve synchronization; suspending the flow of each of said data streams in response to the assertion of said hold signal and upon the detection of the subsequent ECS within each particular data stream; and resuming the flow of each of said data streams simultaneously upon the detection of the ECS associated with the most delayed in time data stream.
