TSW200E1

Appendix B – 2 Mbps PCM Frame Structure

Following ITU-T Recommendation G.704, the 2048 Kbps PCM frame consists in 256 bits

organized in 32 octets (bytes), better known as timeslots. There are four PCM types: PCM30,
PCM30C, PCM31, PCM31C. The PCM30 structure has CAS on timeslot 16. For PCM31, timeslot
16 is a normal signalling channel. The PCM30C and PCM31C have CRC-4.
