Re: Upgrades for High Density Voice Modules

Each PVDM-12 contains 3 TI 549 DSPs and can

run up to twelve voice calls using a low complexity CODEC (G.711, G.729a/b, G.726)

or Runs up to six voice calls using a high complexity CODEC (G.729, G.728, G.723.1).

The module you have presently a NM-HDV-1E1-12 has a

Single-port, 12-channel E1 voice/fax Network Module (supports 12-channels

of medium complexity VoCoders: G.729a/b, G726, G.711 and fax or 6 channels of

G.726, G.729, G.723.1, G.728, G729a/b, G.711 and fax). This product can be

upgraded to an NM-HDV-1E1-30 simply by adding two additional PVDM-12= modules, which mean, you now have three PVDM-12 which supports 12 calls at medium complexity

and six call at high complexity.

With three PVDMS you can suport 36 calls at medium and 18 calls

at high complexity.

You need to order two additional PVDM-12 for your upgrade. Thepart number is as below.

PVDM-12= PVDM-12=, 12-CHANNEL PACKET VOICE/FAX DSP MODULE
