HIGH-DENSITY DIGITAL VOICE/FAX NETWORK MODULES

FOR CISCO 2600XM/2691/2800/3700/3800

IP Communications High-Density Digital Voice/Fax Network Modules for the Cisco 2600XM, Cisco 2691, Cisco 2800,

Cisco 3700 and Cisco 3800 Series Multiservice Access Routers

The IP Communications High-Density Digital Voice/Fax Network Modules are the latest addition to the Cisco Systems

IP Communications

suite of solutions. The IP Communications High-Density Digital Voice/Fax Network 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. The

network modules 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

2600XM, Cisco 2691, 2811, 2821, 2851, Cisco 3700 Series and Cisco 3800 Series Access Routers for either IP

Communications capabilities or pure toll bypass. The IP Communications High-Density Digital Voice/Fax Network Modules flexibly operates

within two different Cisco AVVID (Architecture for Voice, Video and Integrated Data) IP Telephony environments—the Cisco CallManager

system with Survivable Remote Site Telephony (SRST) or Cisco CallManager Express. The network modules can be integrated with these IP

Telephony solutions in a Multiservice Access Router, to provide a complete IP Communications solution for full service branch customers.

Cisco IP Communications solutions provide the means for integrating voice and data allowing users to take advantage of services such as IP

telephony, integrated services, and toll-bypass. These solutions allow enterprises, managed network service providers, and service providers to

reap the advantages of IP telephony such as lower operating costs and increased productivity. Cisco IP Communications solutions also enable

packet voice technologies including voice over IP (VoIP) (including H.323, Media Gateway Control Protocol (MGCP), and Sessions Initiation

Protocol (SIP), voice over Frame, voice over ATM (including AAL2 and AAL5 adaptation layers).

The IP Communications High-Density Digital Voice/Fax Network Modules are an integral part of the Cisco IP Communications offering,

delivering a versatile combination of digital voice, analog voice, and data capabilities in a single network module form factor. They not only

provide the IP telephony gateway to Cisco AVVID architectures for calls to and from the PSTN and the WAN, but also allow enterprises to

deploy networks with existing traditional telephony equipment until they are ready to migrate to IP telephony. Features include high-density

digital voice and WAN connectivity up to four T1/E1 ports, analog voice connectivity up to four ports, and up to 50 conferencing and

transcoding sessions. Enterprises can now deploy all these rich features on a single network module, enabling connectivity to the PSTN,

traditional telephony equipment such as PBXs, key systems, analog telephones, fax machines, and the enterprise WAN.

This product supports three network module versions, with the option of zero, one, or two built-in T1/E1 ports, as shown in Table 2. Each

built-in port can be conveniently software-configured to support either T1 or E1 operation. Each network module also supports a single

VIC/VWIC slot that can be fitted with a Cisco voice/WAN interface card (VWIC) or voice interface card (VIC). The Cisco VICs are daughter

The Cisco VWICs are daughter cards that provide the interface to the PBX, PSTN, and/or WAN. Figure 1 shows a NMHDV2-2T1/E1 with two built-in T1/E1 ports and a VIC2-2FXS in the VIC/VWIC slot. Cisco VWICs supported include 1- and 2-port T1 and E1 interface cards with optional drop-and-insert capability along with a G.703 interface card option.
