The IP Communications High-Density Digital Voice/ Fax Network Modules are used with the new PVDM2 Packet Fax/ Voice DSP modules, providing scalability from 4 to 120 channels & featuring the latest digital signal processing technology. A maximum of four PVDM2s can be installed on each NM-HDV2 network module. Enterprises can conveniently select the minimum number & density-type PVDM2s depending on the voice channels they are deploying, & scale the number of PVDMs as they exp&. These new PVDM2 SIMMs can be configured for high-, medium- or flex complexity via software. Flex complexity is the default configuration, & in this mode, the network module will dynamically negotiate the appropriate codec (medium or high) on a call-by-call basis depending on the PVDM2s available. In addition, the DSPs on the PVDM2s can be shared across multiple IP Communications High-Density Digital Voice/ Fax Network Modules installed on a Multiservice Access Router. ...
