ABSTRACT:
A first plesiochronic digital signal having a bit rate of 135,000 kbit/s, a second plesiochronic digital signal having a bit rate of 1024 kbit/s, a third plesiochronic digital signal having a bit rate of 2048 kbit/s and a fourth plesiochronic digital signal having a bit rate of 64 kbit/s are multiplexed to form a fifth digital signal having a bit rate of 139,264 kbit/s in a basic frame having a length of 2928 bits and beginning with a 12-bit frame recognition word and having a four-bit message word. The signals are demultiplexed such that the first through fourth digital signals are demultiplexed from the fifth digital signal, in particular using a stuffing process.
