ABSTRACT:
Method and apparatus are disclosed for a programmable multiplexer for converting each of one or more input data signals, with individual data rates, into a second higher data rate signal by mapping contiguously arbitarily assigned Capacity Time Slots (CTSs) in a capacity domain frame to Time Slots in a Time Domain frame (TDTSs) so the TDTSs for each input signal are substantially uniformly spread throughout the TD frame. The programmable multiplexer receives separate input data rate signals which are clock synchronized to the multiplexer clock from separate synchronizers, and maps the capacity domain of the input signals to the time frame format using a 2-step or 3-step digit reverse technique. Both techniques decompose the capacity domain address into predetermined digits from predetermined number bases and then combine the digits to perform a similar computation using the number bases in reverse order. The 3-step technique uses an intermediate step of translating the initially determined values for each the predetermined digits using a bit reversal technique.
