ABSTRACT:
In a data transmission method employing a synchronous frame combining asynchronous cells with isochronous channels, a first channel of each frame is reserved for control data independent of the data to be transmitted. Second channels of each frame in a multiframe are reserved for path service data divided between a first group of a specific number of the second channels having specific channel numbers reserved for asynchronous data cell service octets and a second group of second channels which specify the number of isochronous data channels used during the frame of which each forms part. The third channel of each successive frame is at least partially reserved for a code defining a cell start channel number for any cell in the frame in question.
