Description: This table describes the MTA-supported codec types. An MTA MUST populate this table with all possible combinations of codecs it supports for simultaneous operation. For example, an MTA with two endpoints may be designed with a particular Digital Signal Processing (DSP) and memory architecture that allows it to support the following fixed combinations of codecs for simultaneous operation:

Codec Type Maximum Number of Simultaneous Codecs PCMA 3

PCMA 2 PCMU 1

PCMA 1

PCMU 2

PCMU 3

PCMA 1 G729 1

G729 2

PCMU 1 G729 1

Based on this example, the entries in the codec table would be:

pktcSigDev pktcSigDev pktcSigDev CodecComboIndex CodecType CodecMax 1 pcma 3 2 pcma 2 2 pcmu 1

3 pcma 1 3 pcmu 2 4 pcmu 3 5 pcma 1 5 g729 1 6 g729 2 7 pcmu 1 7 g729 1

An operator querying this table is able to determine all possible codec combinations the MTA is capable of simultaneously supporting.

This table MUST NOT include non-voice codecs.
