VI.4.3 G711
If we select G711, we can choose between A law or Mu Law.
G722:
No parameters to configure.
VI.4.4 MPEG Layer II
The configuration steps are:
1. Bit rate.
2. Mode: MONO, JOINT STEREO, STEREO or DUAL.
3. Sample rate: 48, 32,24 or 16 KHz
4. CRC validation on/off.
5. Auxiliary data on/off.
If NET = ISDN Bit Rate > 128 Kbps
If NET = ISND Bit Rate < 64kbps is not possible.
If NET = ISDN & Bit Rate = 128 Kbps, J52, CCS & Telos bonding
algorithms are available. J52 is available from version 4.2.2 onwards.
If the Bit rate > 128 Kbps a 24 Khz sample rate is not possible.
If the Bit Rate > 192 Kbps MONO mode is not possible.
VI.4.5 MPEG Layer III
The configuration steps are:
1. Bit rate.
2. Mode: MONO, JOINT STEREO, STEREO or DUAL.
3. Sample rate: 48, 32,24 or 16 KHz
4. CRC validation on/off.
5. Auxilliary data on/off.
7
16 Khz sampling rate on Mpeg Layer II will be only available with SIP/SAP as streaming IP
protocol.
8
16 Khz sampling rate on Mpeg Layer III will be only available with SIP/SAP as streaming IP
protocol.
