The PVDM3 provides higher density and 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 and 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- and 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 and 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- and 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) and 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.
