Overview

High-density packet voice digital signal processor (DSP) modules (PVDM2) installed on the voice
feature card convert voice and fax calls into IP packets or frames that can be transmitted as voice over
IP (VoIP) over a variety of transport technologies on Cisco AS5350XM and Cisco AS5400XM universal
gateways. The number of calls supported depends on the number of PVDM2 modules installed on the
voice feature card, and the number of voice feature cards installed in the chassis.
The voice feature card supports a 64-channel PVDM2 (AS5X-PVDM2-64) module. You can install up
to six AS5X-PVDM2-64 modules on each voice feature card.
of channels supported by each AS5X-PVDM2-64 module and the maximum number of channels
supported by a voice feature card with six AS5X-PVDM2-64 modules installed.
