ABSTRACT:
A communication network element (536) comprises a transmitter (535) for transmitting at least one timing data packet to at least one further network element (524) over both a first communication link and a second communication link and a receiver (537) for receiving two timing data packets from the at least one further network element (524) over the second communication link. The communication network element (536) further comprises signal processing logic (538) operably coupled to the transmitter and receiver and arranged to calculate a transit delay of the at least one timing data packet over the first communication link based on the received two timing data packets from the at least one further network element (524) over the second communication link, wherein the signal processing logic (538) is capable of scheduling at least one transmission across the first communication link to the at least one further network element (524) in response thereto.
