Brand: Cisco · SKU: PVDM · MPN: Varies by model (e.g., PVDM3-256) · Category: Components
The PVDM (Packet Voice Digital Signal Processor Module) is a hardware module from Cisco that provides Digital Signal Processor (DSP) resources to Integrated Services Routers (ISRs). These resources enable collaboration services such as voice sessions, transcoding sessions, conference sessions, and video capabilities for Cisco Unified Communications solutions. PVDMs can be populated with one or more DSPs, with more DSPs providing greater processing power. Different generations exist, including PVDM2, PVDM3, and PVDM4, supporting various Cisco ISR platforms (e.g., 2800/3800 series for PVDM2; 2900/3900 series for PVDM2/PVDM3; 4000 series for PVDM4 and service modules like SM-X-PVDM). PVDM3 modules offer up to four times the channel density of PVDM2 modules and support video, whereas PVDM2 generally supports voice/fax. The number in the model name (e.g., PVDM3-256) typically indicates the maximum number of G.711 voice channels supported.
