The PVDM2-16 reaches its 16 channels with one DSP: a maximum of 16 channels with the G.711 codec, 8 with medium-complexity codecs and 6 with high-complexity codecs. The DSP is a Texas Instruments TNETV2510GGW at 200 MHz with 128 megabits of external synchronous dynamic RAM.
The PVDM2-16 is a Cisco 16-channel packet fax/voice DSP module that plugs into an 80-pin SIMM slot and can be inserted or removed in the field. It handles compression, voice activity detection, jitter management and echo cancellation, with echo tail coverage of 64 ms to ITU-T G.168, and it supports universal transcoding with host software.
It fits the NM-HDV2, NM-HDV2-1T1/E1 and NM-HDV2-2T1/E1 network modules (four PVDM2 slots each) and the EVM-HD-8FXS/DID, EM-HDA-8FXS and EM-4BRI-NT/TE modules. The spare number is PVDM2-16=.
Larger modules in the same family are the PVDM2-32, PVDM2-48 and PVDM2-64, and the smaller one is the PVDM2-8. Browse related voice cards in Cisco interface cards.
