Transmission of D-channels in telecommunications systems

摘要

The invention is a circuit for transmitting digital information which avoids wasting bandwidth when one channel is transmitted at a slower rate than another channel. A superframe (80) is set up to include a plurality of multiplexed frames (40, 50, 60, 70). At least one of the bursts (41, 51, 61 and 71) in each frame is shared by a plurality of customers so that each customer can transmit a full payload once for each superframe. <IMAGE>
