Vocality V100 Analogue Voice Card (2, 4 or 8 Channels)
Compressed toll-quality telephony channels are available in any combination from a wide range of ITU-standard algorithms. These may be individually selected according to bandwidth and quality requirements, with bit rates from 5.3Kbps up to 64Kbps. All channels support Group 3 FAX at 2400-14400bps and provide G.168 echo cancellation. Bandwidth is dynamically assigned to optimise link use. Input/output gain adjustment allows the voice circuits to be optimised for all situations.
The analogue voice cards are available in 4 or 8 channel form and provide FXO, FXS and 4-wire E&M (Tie-line) interfaces for connection to private analogue circuits. DTMF, MF and E&M signalling standards are supported.
