13.2 Dual Digital Voice Compression Card

A C31 DSP-based Dual Digital Voice Compression (DDVC) Card must b
installed with an ISDN BRI-S/T I/O Card to provide compressed voice capability 
to the CX900e. The card can be mounted in any I/O slot but we recommend that it 
be installed next to the ISDN BRI-S/T I/O Card.

WARNING: The DDVC (Dual Digital Voice Compression) Card   cannot coexist 

with the following C54 DSP-based cards in the same CX900e chassis:
- Dual Analog Voice I/O Card (DAV I/O)
- BRI Digital Voice I/O Card (BRI-DV I/O)

The DDVC provides two voice channels that can be software configured for voice 
compression at 5.8 or 8.0 Kbps (ACELP II) or 16, 24, 32 or 40 Kbps (G.726), o
64 Kbps (PCM). 

NOTE: Each CX900e chassis can support a maximum of two DDVC Cards (4 voice 

channels).

The power consumption for the card is 3 Watts (10.3 BTU/hr).
