Three DSPs and 720 MIPS in flex mode make up the PVDM2-48, a Cisco packet fax/voice DSP module. The 48 in the name is the G.711 maximum. With medium-complexity codecs it reaches 24 channels, and with high-complexity codecs 18, at 8 and 6 calls per DSP.
Modem relay, iLBC, G.723.1, G.728, G.729 and G.729b run as high-complexity codecs. G.711, G.729a, G.729ab, G.726, G.722 and fax relay run as medium-complexity codecs, and G.711 gets the highest density.
The module plugs into an 80-pin SIMM slot and goes into the NM-HDV2, NM-HDV2-1T1/E1 and NM-HDV2-2T1/E1 network modules, the EVM-HD-8FXS/DID, EM-HDA-8FXS and EM-4BRI-NT/TE modules, and the onboard slots of Cisco 2801, 2811, 2821, 2851, 3825 and 3845 routers. Cisco 2911, 2921, 2951, 3925 and 3945 routers reach the slot through the PVDM2-ADPTR adapter. The spare number is PVDM2-48=.
The family also has the PVDM2-8, PVDM2-16, PVDM2-32 and PVDM2-64. Browse further voice and DSP modules in Cisco interface cards.
