Abstract
An accurate non-Data Over Cable Service Interface Specification (non-DOCSIS) clock signal is generated at the downstream output of a DOCSIS network. In one example method, a downstream DOCSIS Timing Protocol (DTP) client in the DOCSIS network is frequency synchronized to an upstream DTP server in the DOCSIS network. DOCSIS timing information, along with one or more timing correction factors received at the DTP client, is used to time synchronize the DTP client to the DTP server. Based on the time and frequency synchronization between the DTP server and the DTP client, the clock signal is generated at the output of the DTP client in accordance with the non-DOCSIS timing protocol.
