Abstract
A method and a TDM multiplexer by which circuit-switched synchronous data and packet-switched asynchronous data are optimally combined for transmission over a common channel. Time slots of variable width are assigned to circuit-switched traffic, while the remaining capacity of the TDM frame is used for transmission of store-and-forward traffic which is inserted in the gaps between assigned time slots in the form of an intermittent bit stream.
