Abstract:
1. A method of generating a plurality of layer 1 frames, having a common frame format, from a plurality of types of layer 2 data, including Synchronous Transfer Mode (STM) signals, Asynchronous Transfer Mode (ATM) cells, primary Internet Protocol (IP) packets, and best effort IP packets, the method comprising: forming a payload for a layer 1 frame that includes the data of a layer 2 frame; forming, based on a type of the data of the layer 2 frame, a layer 1 frame header including: outputting the layer 1 frames in the common frame format, where the layer 1 frames that include the STM layer 2 data are periodically output, and when an idle transfer space immediately precedes a particular layer 1 frame that includes the STM layer 2 data being output:
