Method and device for converting digital channel multiframes into packet multiframes

Abstract From the Canadian patent

The method consists in converting an inputting multiframe including of M frames each having words assigned respectively to C multiplexed digital channels into an outgoing multiframe including of C packets each having M words of a respective channel. So as to only use a single memory, a word having a given rank in the outgoing multiframe and a word having said given rank in the inputting multiframe are read and written consecutively in a same cell of the single memory. The memory has a capacity at least equal to MC word cells. The MC cells are addressed according to an address order rebecoming identical to itself after a cycle of N multiframe periods, where N is the smallest integer so that …
