384 Kbps is not an option with MPEG Layer III.
If NET = ISDN & Bit Rate = 128 Kbps, Telos Layer III bonding algorithm is
available.
If NET = ISDN Bit Rate > 128 Kbps is not possible.
If NET = ISND Bit Rate < 64kbps is not possible.
If the Bit rate > 128 Kbps a 24 Khz sample rate is not possible.
VI.4.6 AAC 2,4 LC
The configuration steps are:
1. Bit rate.
2. Mode: MONO, JOINT STEREO, STEREO or DUAL.
3. Sample rate: 48, 32 or 24 KHz.
4. CRC validation on/off.
5. Auxiliary data on/off.
If NET = ISDN Bit Rate > 128 Kbps is not possible.
If NET = ISND Bit Rate < 64kbps is not possible.
If the Bit rate > 128 Kbps the combination MONO - Fs= 24 KHz is not possible.
If the Bit Rate > 192 Kbps the combination MONO - Fs= 32 KHz is not possible.
If the Bit Rate > 256 Kbps the combination MONO is not possible.
If the Bit Rate > 256 Kbps the combination STEREO – Fs = 24 KHz is not
possible.
If NET = ISDN & Bit Rate = 64 or 128 Kbps, J52 protocol is available. J52 is
available from version 4.2.2 onwards.
VI.4.7 AAC LD
The configuration steps are:
1. Bit rate.
2. Mode: MONO, JOINT STEREO, STEREO or DUAL.
3. Sample rate: 48, 32 or 24 KHz.
4. CRC validation on/off.
5. Auxiliary data on/off.
