Generation of primary rate clocks from correction values derived from the received Synchronous Residual Time Stamp

摘要

A method of generating a clock from a signed correction value derived from cells carrying timing information in an asynchronous network involves deriving a decrement/increment indicator from the sign of the received correction value. A local clock is incremented and decremented in a predetermined period accordance with said decrement/increment indicator and the true magnitude of the received correction value.
