Abstract

In a system where subrate multiplexing is used for efficient data transfer, demultiplexing the data in a quick and flexible manner can be very complex and expensive. The GSM Digital Cellular System Transcoder to Channel Coder Interface provides an example where four 16kbit/s data timeslots are packed into a single 64kbit/s timeslot on a 2Mbit/s serial data stream for transfer between the Base Site Con- troller (BSC) and the Base Transceiver Station (BTS).
