| 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. |
