Patent ID: 7782812

Claim:
A method of transmitting data by a communication system comprising steps of: receiving first type payload data and second type payload data, the first type payload data including two data streams corresponding to different clocks; synchronizing, with a synchronizer, the received first type payload data thereby generating a synchronized data rate; assigning the synchronized first type payload data in bit positions of a frame; distributing the second type payload data in unassigned bit positions of the frame as a function of the synchronized data rate; and transmitting the frame wherein the frame includes plural sub-frames with plural blocks and sub-blocks, each sub-block including a synchronized first type payload data bit position or a second type payload data bit position and each block having at least one overhead bit position; inserting a frame alignment word in bit positions of a first block of the plural blocks and sub-blocks of the first sub-frame; and distributing synchronized first type payload data bits or second type payload data bits in unused overhead bit positions of other blocks.
