ABSTRACT:
Disclosed are a method of and system for enabling the transport of timer protocols over a generic frame procedure (GFP) network. The method comprises the steps of transmitting a defined optical initialization sequence to a GFP mapper, and using that GFP mapper to detect the optical initialization sequence and to generate a specified GFP frame to represent the initialization sequence. This specified GFP frame is recognized as a control frame for timer initialization. In a preferred embodiment, the timer protocol uses biphase encoding to encode clock data, and the method comprises the further steps of recovering clock data from a data stream that uses the biphase encoding, detecting a clock rate in that data stream, and using a look up table to map said detected clock rate into a specific code for said control frame.
