Summary

This Recommendation specifies the elements of DCME using 8 kbit/s CS-ACELP, Digital Speech Interpolation (DSI) and facsimile demodulation/remodulation in order to achieve interworking of such equipment. It specifies extensions and deviations for ITU‑T G.763, ITU‑T G.766 and ITU‑T G.767 which specify a 32 kbit/s ADPCM DCME, and facsimile demodulation/remodulation and 16 kbit/s LD-CELP DCME respectively.
