Cisco Systems PVDM3-16U192 - PVDM3 16-Channel to 192-Channel Factory

The Cisco High-Density Packet Voice Digital Signal Processor Module (PVDM3) is supported on all Cisco 2900 and 3900 Series platforms part of the Cisco Integrated Services Routers Generation 2 (ISR G2) portfolio.
It provides higher density and more processing power than the PVDM2 making the addition of rich-media applications possible. Enhanced DSP architecture accommodates a new packet-processing engine optimized for rich-media voice applications while concurrently supporting the time-division multiplexing IP (TDM-IP) voice framework used by the PVDM2.
