..................Algorithmes
ISDN
Data rate : 64 kbit/s or 128 kbit/s
ITU-T G722 H221 / H242 or G722 SRT
• One ISDN "B" channel (64 kbit/s) 7 kHz, < 10 ms delay
ISO MPEG Audio:
• One or two ISDN “B” channels
• Sampling frequency** : 48 kHz, 32 kHz, 24 kHz or 16 kHz
• J52 compliance : enable or disable
The IUT J52 protocol provides :
• Standardized interworking protocol
• Reed-Solomon error correction
• Asymmetric transmission capability
4 SB ADPCM*
• Less than 10 ms delay
• Two ISDN “B” channels, 15 kHz, FS = 32 kHz
TDAC** (option)
• One ISDN “B” channel (64 kbit/s) 15 kHz, FS = 32 kHz
G711
• “digital hybrid”, or fall back operation (telephone mode).
PSTN (POTS)
Data rate : from 24 kbit/s down to 12 kbit/s
CELP voice modelling
• 80 ms delay,
• Audio bandwidth : 40 Hz to 7.2 kHz @ 24 kbit/s (typical).
The maximum data rate depends on the line quality.
*Depending on model
