Abstract:
A method for combining a plurality of data streams into an aggregate data stream, the method comprising the steps of:encoding a first plurality of 8 bit data words from a first data stream into a first plurality of corresponding 10 bit data words in which each 10 bit data word represents a respective 8 bit data word from said first data stream;encoding a second plurality of 8 bit data words from a second data stream into a second plurality of corresponding 10 bit data words in which each 10 bit data word represents a respective 8 bit data word from said second data stream;combining said first plurality of corresponding 10 bit data words and said second plurality of corresponding 10 bit data words into an aggregate output stream, said aggregate output stream divided into a plurality of timeslots;encoding a plurality of 10 bit words into a corresponding plurality of special characters that do not correspond to any of said first or second plurality of 8 bit data words;periodically inserting said special characters into said aggregate output stream; andinserting a first special character into a first of said plurality of timeslots, said first special character allowing a receiver to synchronize to said aggregate output stream.
