Special PVDM2 expansion modules have been developed for the new NM-HDV2 multiservice modules, which are installed in internal SIMM connectors located on the module. In total, up to 4 PVDM2 modules are supported. These PVDM2 modules contain DSP processors on which voice streams are processed. The following PVDM2 modules are available: PVDM2-8, PVDM2-16, PVDM2-32, PVDM2-48, PVDM2-64.

Support for new NM-HDV2 modules has been implemented in Cisco IOS software since version 12.3(7)T IP Voice and will continue in later releases.

The cost of modules according to the GPL price list is $1 495, $2 495, $3 195 for NM-HDV, NM-HDV2-1T1/E1 and NM-HDV2-2T1/E1 respectively. Delivery from the Race Communications warehouse in Moscow or within 6-8 weeks.
