Abstract:
1. An Optical Transport Network multiplexing method for full transparent transport of datacom and telecom signals, comprising: receiving one or more client signals; assigning the one or more client signals to a set of time slots of a plurality of time slots in an Optical Channel Payload Unit; utilizing one or more fixed stuff columns as a coarse adjustment and one or more fixed stuff bytes, multi-frame stuff bytes, and/or additional payload bytes as a fine adjustment to bias a justification range required for the one or more client signals in the set of time slots, wherein the additional payload bytes are overhead bytes containing payload; utilizing the fixed stuff columns, fixed stuff bytes, multi-frame stuff bytes, and/or additional payload bytes to bias the justification range such that no more than one negative and no more than four positive justification opportunities are required; utilizing a multiplex signal identification in an Optical Channel Payload Unit overhead that is synchronized to a multi-frame identification also in the Optical Channel Payload Unit overhead to indicate the assignment of the one or more client signals to a tributary identification and a level for each time slot; and utilizing shared justification control overhead that is also synchronized to the multi-frame identification.
