Zusammenfassung:This disclosure describes a method and apparatus for signaling the phase and frequency of OTN and Constant Bit Rate (CBR) clients in an OTN network. The principles discussed are applicable when multiple stages of OTN multiplexing and demultiplexing are utilized. They are also applicable for use with the Generic Mapping Procedure (GMP) and Asynchronous Mapping Procedure (AMP). A method to use the phase and frequency of an ODUk/ODUflex to adjust a local reference clock to enable the recovery of the phase and frequency of a CBR client demapped from the ODUk/ODUflex is described.
