SYSTEM AND METHOD FOR MAPPING SIGNALS TO A DATA STRUCTURE HAVING A FIXED FRAME SIZE

摘要

A method and apparatus for mapping digital data signals in an optical communication system (100) to a data structure having a fixed frame size (200). A justification indicator (302) and a negative stuff location (304) are allocated in frame overhead to accommodate positive/negative/zero justification. A multiplexing method to establish a hierarchy of such data structures using the same technique is also described.
