Abstract:
1. A method for transmitting an STM-256/OC-768 data signal having a higher byte rate than the STM-64/OC-192 data signal, the method comprising the steps of: dividing the data signal byte by byte into four concatenated subsignals by removing unused bytes of overhead and frame alignment bytes; forming modified STM-64/OC-192 pulse frames, which have a reduced number of frame alignment bytes; inserting the subsignals into the modified pulse frames; inserting a corresponding number of bytes of, in each case, one of the subsignals into each modified pulse frame instead of the frame alignment bytes no longer transmitted; inserting remaining bytes of the respective subsignal into unused time slots of an overhead and a payload of the modified pulse frame; transmitting the subsignals; and combining the subsignals again at a receiving end to form an STM-256/OC-768 data signal at the receiving end.
