The High-Density Packet Voice Feature Card for Cisco AS5350XM and AS5400XM Universal 
Gateways (product number AS5X-FC) feature supports up to six high-density packet voice/fax digital 
signal processor (DSP) modules (product number AS5X-PVDM2-64), increasing the density of the 
feature card to 384 low-complexity or 192 medium-complexity or 144 high-complexity VoIP calls.

The High-Density Packet Voice Feature Card for Cisco AS5350XM and AS5400XM Universal 
Gateways (referred to here as the High-Density Packet VFC) with one to six PVDM2-64 modules can 
provide the correct number of DSPs depending on the codec type needed and Cisco AS5350XM and 
Cisco AS5400XM trunk configuration. 

You can select the minimum number of PVDM2-64 modules depending on the voice channels currently 
needed, and then add PVDM2-64 modules as requirements expand. The High-Density Packet VFC 
supports T1/E1 and CT3 configurations.

The High-Density Packet VFC is designed to work with basic software configurations on 
Cisco AS5350XM and Cisco AS5400XM platforms without requiring specific configuration changes. 
However, there are some changes to existing command-line interface (CLI) commands that enable you 
to customize and troubleshoot your configuration to improve performance. These commands are 
described in the 

“Command Reference” section on page 28
