Description

The PVDM4 factory upgrade raises a packet voice DSP module for the Cisco ISR 4000 from 32 to 128 G.711 channels. It suits voice gateway deployments that need greater call capacity from the router's PVDM4 slot. This is a 32 to 128 channel factory upgrade applied at build time, so it is specified when the router is configured rather than added afterwards.

Enquire with XS Network Tech for new or used pricing and availability.
