Abstract
A packet voice/data communication system provides a frequency measurement isochronous clocking transmission capability. This is a method of transferring clock information by directly measuring the frequency of the clock relative to a reference and then reproducing that exact clock frequency at the far end relative to the reference which has been carried through the system.
