Abstract
For use in a transmission system in which an input data stream is transmitted in plural data streams each at a fraction of the input data stream rate and plural clock stream pairs each at the fraction of the input data clock rate, a receiver, comprised of apparatus for receiving the plural data streams, apparatus for determining frame timing differences between frame signals contained in each of the received plural data streams, apparatus for varying the timing of one received data stream relates to another, whereby their relative timing is adjusted, apparatus for combining the timing adjusted plural data streams into an output data stream having a similar data stream rate as the input data stream, apparatus for recovering a clock from one of the plural data streams, and for generating an output clock signal therefrom at the input data clock rate, and apparatus for aligning the output data stream with the output clock signal, whereby an output data stream and an output clock signal are provided having similar data rates as the input data stream and clock rates.
