Cisco Module VIC3-4FXS/DID

IP Communications High-Density Digital Voice/Fax Network Modules

The IP Communications High-Density Digital Voice/Fax Network Modules are an addition to the Cisco Systems' IP Communications suite of solutions. These modules deliver high-density digital voice connectivity, high-density WAN connectivity, analog voice connectivity, and conferencing and transcoding capability in a network module form factor.

They provide enterprises, managed service providers, and service providers with the ability to directly connect the public switched telephone network (PSTN), traditional telephony equipment (such as private branch exchange (PBX), key systems, analog telephones, and fax machines), and WAN to Cisco 2811, 2821, 2851, 2911, 2921, 2951, 3825, 3845 and 3925, 3945 Unified Communications Routers for either IP Communications capabilities or pure toll bypass.

The IP Communications High-Density Digital Voice/Fax Network Modules flexibly operate within two different Cisco Unified Communications (UC) environments - the Cisco Unified Communications Manager (UCM) system with Survivable Remote Site Telephony (SRST) or Cisco Unified Communications Manager Express (UCME).

The network modules can be integrated with these IP Telephony solutions in a Unified Communications Router, to provide a complete IP Communications solution for full service branch customers.
