Single-port, 12-channel E1 voice/fax Network Module (supports 12-channels of medium complexity VoCoders: G.729a/b, G726, G.711 and fax or 6 channels of G.726, G.729, G.723.1, G.728, G729a/b, G.711 and fax). This product can be upgraded to an NM-HDV-1E1-30 simply by adding two additional PVDM-12= modules.
This complete bundle includes one (1) NM-HDV=, one (1) PVDM-12=, and one (1) VWIC-1MFT-E1.

The Digital T1/E1 Packet Voice Trunk Network Module provides a flexible and scalable T1/E1 voice solution for Cisco 2600, 2600XM, 2811, 2821, 2851, 2691 3600, 3700 series and 3800 series multiservice Modular Access routers and supports up to 60 voice channels in a single network module. A single packet voice trunk network module supports both on-premise and off-premise connections to both Private Branch Exchanges (PBXs) and Public Switched Telephone Networks (PSTNs). These products are ideal for enterprise branches, large businesses and service providers wishing to migrate to packet-based multiservice infrastructures. This network module leverages existing legacy telephony equipment investments in addition to providing the ideal gateway interface for IP telephony within the Cisco Architecture for Voice, Video and Integrated Data (AVVID). It also enables the deployment of new packet voice applications while reducing recurring telephony charges.
The Digital T1/E1 Packet Voice Trunk Network Module uses a real-time cpu and powerful digital signal processors (DSPs) which support all functions needed to provide the highest levels of voice fidelity and quality, eliminating the processing burden from the Cisco 2600/2600XM/2691/2800/3600/3700/3800 main CPU. These DSPs can be scaled to support from six to 60 voice channels in a single Network Module using a number of different voice compression algorithms. The packet voice trunk network modules include a MultiFlex Voice/WAN interface card (VWIC) which offer single and dual port T1 or E1 interfaces for additional versatility and scalability. This flexibility allows voice and fax traffic to travel cost-efficiently across a user's wide area network (WAN) or directly over the PSTN.
