摘要: An Inverse Multiplexer is disclosed which first demultiplexes a first data rate input signal into a plurality of second lower data rate subsectional signals, where each subsectional signal is provided with a periodic synchronization marker and includes a data rate which is less than the channel data rate used to transmit that subsectional signal to a remote terminal. Programmable Multiplexers (PMUXs) then operate to each take one or more subsectional signals that are (1) clock synchronized to a PMUX clock, and (2) a rational fraction of the channel data rate, and map contiguously assigned time slots in a capacity domain frame for each subsectional signal to time slots of a time domain frame format using a 2-step or 3-step digit reverse technique. The resultant time domain format has the input subsectional capacity domain time slots substantially uniformly distributed over the time domain frame. At the receiving end, an Inverse Demultiplexer performs the reverse operation to recover the original first data rate input signal.
