Cisco 128-Channel High-Density Packet Voice And Video Digital Signal
Processor Module

Product Description

The PVDM3 provides higher density & more processing power than the PVDM2, making the addition of rich-media applications possible. Enhanced DSP architecture accommodates a packet-processing engine optimized for rich-media voice & video applications, while concurrently supporting the time-division multiplexing IP (TDM-IP) voice framework used by the PVDM2. The PVDM3 module portfolio has up to 4 times higher density than those in the PVDM2 portfolio. In addition, the PVDM3 modules provide better density for medium- & high-complexity codecs than their equivalent PVDM2 peers. For example, the number of supported medium-complexity codec on a PVDM3-64 is 42, versus 32 on a PVDM2-64. Features High density & flexibility The PVDM3 module portfolio has up to 4 times higher density than those in the PVDM2 portfolio. In addition, the PVDM3 modules provide better density for medium- & high-complexity codecs than their equivalent PVDM2 peers. For example, the number of supported medium-complexity codec on a PVDM3-64 is 42, versus 32 on a PVDM2-64. Voice-quality management The PVDM3 modules perform compression, voice-activity-detection, jitter-management, and echo-cancellation functions. The echo cancellation offered in the PVDM3 modules has a tail length of 128 milliseconds (ms) & complies with ITU-T G.168. Energy-saving feature The PVDM3 DSPs offer multiple power-saving modes, including a power-saver mode when the module is not in use. In power-saver mode each PVDM3 can save up to 5 watts of power.
