ISDN BRI-S/T DIGITAL VOICE I/O CARD
The ISDN BRI-S/T Digital Voice I/O card mounts on the motherboard in any of
slots 1-6. It enables the CX900e to transmit compressed voice, and data over an
ISDN BRI-S/T interface. The B channels can be software configured for voice
compression at 8.0 Kbps (G.729) and 40, 32, 24, or 16 Kbps (G.726), or 64 Kbps
(G.711).
WARNING: The ISDN BRI-S/T Digital Voice I/O card cannot coexist with the fol-
lowing C31 DSP-based cards in the same CX900e chassis:
- Analog Voice I/O Card
- Dual Digital Voice Compression (DDVC) Card
In networks where the telco supplies Network Termination 1 (NT1), the CX900e
must use an ISDN-S/T (4-wire) interface.
