The PVDM2-36DM is a high-density digital modem module that provides 36 independent V.90/V.92 voice and data channels for Cisco ISR G2 routers. It enables simultaneous analog dialup, voice, fax and dial backup services.
The PVDM2-36DM is supported on Cisco 2900, 3900 and 4000 Series Integrated Services Routers (ISR G2) with a dedicated PVDM2 slot. Verify your router’s hardware and IOS compatibility matrix before deployment.
The module supports up to 36 simultaneous digital modem channels, each capable of voice, fax or data at V.90/V.92 speeds, enabling robust multi-session connectivity.
It supports V.90 and V.92 analog modem standards, V.34/V.17 fax, and industry standard DTMF and Loop Start signals for seamless voice and fax interoperability.
Licensing is built in: no additional license is required. Once the module is installed and recognized by the router, all 36 ports are enabled automatically.
The module draws approximately 15 Watts under typical load. Confirm your router’s power budget to ensure adequate margin for all installed line cards.
Power down the router, insert the PVDM2-36DM into the dedicated PVDM2 slot, secure with screws, then power on. The router will auto-detect the module on boot.
Yes. Cisco ISR G2 routers support multiple PVDM2 modules in separate slots, allowing combined capacity of varied port density modules.
The module measures 1.5” H x 8.6” W x 10.5” D and weighs approximately 0.8 pounds, fitting standard rack-mounted Cisco ISR chassis.
Operating temperature: 0°C–40°C (32°F–104°F); storage: –40°C–70°C (–40°F–158°F); humidity: 10–90% non-condensing, ideal for data center or office deployment.
The module contains 18 DSP engines, each supporting two independent channels for voice, fax or data, delivering efficient signal processing performance.
Cisco provides a limited lifetime warranty on hardware defects, plus access to Cisco Technical Assistance Center (TAC) and software maintenance under a SmartNet service contract.
Ensure your router runs a Cisco IOS Universal image release 15.1(4)M or later with the ‘voice’ feature set enabled for full PVDM2-36DM functionality.
Typical applications include analog dial-in access, fax consolidation, remote office dial backup, voice mail gateways and legacy modem support in enterprise edge networks.
Use the Cisco CLI commands ‘show controllers modem chassis’ and ‘show diag slot <slot-number>’ to verify channel status, firmware revision and hardware health.
