| Annex H: Mapping of G.721 (1988) and G.728 (1992) into the data component of a voice body part |
 |
AbstractThis amendment contains the proposed technical revisions to Recommendation X.440 (1992) that:1) Resolve the "For further study" item contained in Recommendation X.440 (1992) by specifying a mapping between the 4-bit per word encoding of 32 kbit/s ADPCM as defined in G.721 (1988) and X.440's 8-bit per word encoding of OCTETS. It also specifies rules for mapping G.728's 16 kbit/s LD-CELP 10-bit per word encoding onto X.440's 8-bit per word encoding.2) Officially integrate the resolved defect report changes contained in the MHS Implementors Guide version 12. |
