In conjunction with Cisco IOS

Software, the PVDM3 modules support universal transcoding and the same codec
repacketization as the PVDM2 modules. Universal transcoding allows transcoding from any supported codec to
any other supported codec. The PVDM3 modules offer improved universal transcoding session capacity over the
each codec on each PVDM3 module.
The PVDM3 modules support transrating, where repacketization of the same codec is used to connect dissimilar
networks that have different codec packetization periods.
Voice-Quality Management
The PVDM3 modules perform compression, voice-activity-detection, jitter-management, and echo-cancellation
functions. The echo cancellation offered in the PVDM3 modules has a tail length of 128 milliseconds (ms) and
complies with ITU-T G.168.
Energy-Saving Feature
The PVDM3 DSPs offer multiple power-saving modes, including a power-saver mode when the module is not in
use. In power-saver mode each PVDM3 can save up to 5 watts of power.
Cisco Platform Availability
The Cisco High-Density Packet Voice Digital Signal Processor Modules are supported on all Cisco 2900 and 3900
Series platforms. The Cisco 2901 and 2911 have 2 PVDM slots each, the Cisco 2921 and 2951 have 3 PVDM slots
each, and the Cisco 3925 and 3945 have 4 PVDM slots each. Please refer to Table 3 for more information about
the support matrix.
