Wide Range of Codec Support 

The PVDM3 modules support a wide range of codecs of different complexities. They support all codecs that are 

supported by the PVDM2 modules. Table 1 lists the codecs supported on the PVDM3 modules. 

Codec Support on PVDM3 Modules 

G.711, clear-channel, Fax and Modem 
Passthrough  

G.729a, G.729ab, G.726, G.722, and 
Fax Relay 

G.728, G.729, G.729b, Internet Low 
Bitrate Codec (iLBC), and Modem Relay 

High Density and Flexibility 

The PVDM3 modules have up to four times higher density than the PVDM2 modules. In addition, the PVDM3 

modules provide better density for medium- and high-complexity codecs than their equivalent PVDM2 peers. For 

example, the number of supported medium-complexity codecs on a PVDM3-64 is 42, versus 32 on a PVDM2-64. 

Refer to Table 2 for more details about channel density for each PVDM3 module. 

High-end PVDM3 modules such as the PVDM3-192 and PVDM3-256 enable scalable rich-media applications with 

improved user experience and quality. A PVDM3-256 can support up to 60 secure iLBC TDM-IP voice sessions, 

and up to 30 eight-party conferences with the high-fidelity wideband codec G.722.

Conferencing, Transcoding, and Transrating Services  

The PVDM3 modules support digital voice connections, analog voice connections, conferencing, and universal 

transcoding services. The same DSPs on the PVDM3 modules can now support all the services with a single DSP 

image. In addition, the PVDM3 supports a higher number of conference sessions and a higher number of 

participants per conference than the PVDM2. The PVDM3-256 can support up to 6 conferences with 64 

participants in each conference and up to 66 conferences with 8 participants in each conference. Please refer to 

the 

 for more information about the number of supported sessions.
