PVDM4-32 Cisco Network Module 32-Channel Router Voice And Video DSP Module
Product Information
The PVDM4 modules support a wide range of codecs of different complexities. They support all codecs supported by the Cisco 2800/3800 High-Density PVDMs (PVDM3s). Table 2 lists the codecs supported on the PVDM4 and SM-X-PVDM modules, and Table 3 gives the channel densities of the PVDM4 and SM-X-PVDM modules. Table 4 lists the media-enhancement features.
Cisco 4000 Series PVDMs are available in two form factors with four supported densities in each form factor:
● Motherboard PVDMs (PVDM4) for densities up to 256 channels
● PVDM enhanced services modules (SM-X-PVDM) for densities up to 3080 channels
