1-Slot Voice fax Network Module-Spare
On the Cisco 1750, a PVDM (Packet Voice DSP Module) is needed to support the VIC-2E/M. The PVDMs hold digital signal processors (DSPs) that make the card fully functional. The 1750 requires a PVDM-4 for one VIC-2E/M and a PVDM-8 for two VIC-2E/Ms. These PVDMs are installed on the motherboard within the 1750. On the Cisco VG200, 2600, and 3600, the NM-1V and 2Vs come with the DSPs installed on the module.
