- Overview
-
The Cisco® Packet Voice Digital Signal Process Modules (PVDMs) enable Cisco 4000 Series Integrated Services Routers (ISRs) to provide rich-media capabilities such as high-density voice connectivity, conferencing, transcoding, media optimization, transrating, and secure voice f Cisco Unified Communications solutions. These new modules suppt unprecedented scale while allowing f a smaller solution footprint than ever befe.
Features and Benefits
The PVDMs suppt digital voice connections, conferencing, universal transcoding, and media optimization services:
● T1/E1 voice: One of the primary uses of PVDMs is to packetize digital voice into IP packets to enable time-division multiplexing (TDM) digital voice applications.
● Conferencing: PVDM modules suppt ad hoc and meet-me conferencing with various codecs in conjunction with Cisco Unified Communications Manager and Cisco Unified Communications Manager Express.
● Universal transcoding: In conjunction with Cisco IOS® Software, the PVDMs suppt universal transcoding, which allows conversion from any suppted codec to any other suppted codec.
● Transrating: The PVDMs suppt transrating, in which the same codec is repacketized in der to connect dissimilar netwks that have different codec packetization periods.
● Voice-quality management: The PVDMs perfm compression, voice-activity detection, jitter management, and echo cancellation. The echo cancellation offered in the PVDMs has a tail length of 128 milliseconds and complies with ITU-T G.168.
● Energy savings: The motherboard PVDMs (PVDM4s) offer multiple power-saving modes, including a power-saver mode when the module is not in use. In power-saver mode, each PVDM4 can save up to 5 watts of power.
The analog voice modules (FXS, FXO, and E/M) and Basic Rate Interface (BRI) digital voice modules f the 4000 Series ISRs contain built-in, nonconfigurable digital signal processs (DSPs) and do not require any additional PVDMs f voice packetization.
