Abstract
An interworking function (IWF) is coupled to a switch of a packet network and communicates with the network switch based on an Ethernet clock signal or some other type of clock signal. A primary reference clock (PRC) of the network generates a PRC signal, and a timing analyzer determines timing information indicative of timing relationships between the Ethernet clock signal and the PRC signal. The timing analyzer periodically transmits such timing information, and the IWF uses the timing information to generate a PRC signal that is traceable to the network PRC signal.
