Abstract
A system for synchronizing a first network device and a second network device. The first network device comprises an interface configured to release over a communication link a first signal carrying a first data stream clocked by a first clock signal. The second network device comprises an interface configured to receive the first signal over the communication link. The second network device also comprises a clock extraction module configured to generate an extracted clock signal from the received first signal; and a data coding module configured to clock a second data stream with an output clock signal selected based on a speed of a locally generated clock signal relative to the first clock signal or the extracted clock signal, thereby to produce a second signal for transmission from the second network element to the first network element.
