Cisco IP Communications Voice/Fax Network Modules for the Cisco 2800, 2900, 3800, and 3900 Series Unified Communications Routers

The Cisco ® IP Communications voice/fax network modules provide enterprises, managed service providers, and service providers the ability to directly connect the public switched telephone network (PSTN) and traditional telephony equipment (private branch exchange [PBX], key system, analog telephones, fax machines, etc.) to Cisco 2800, 2900, 3800 and 3900 Series Unified Communications routers. This set of Cisco IP Communications voice/fax network modules delivers the most versatile combination of analog and digital voice and data capabilities in a single network module. As a completely integrated component of the Cisco Unified Communications solution including Cisco Unified Communications Manager (UCM), Cisco IP phones, Cisco Unity ® unified messaging software, Cisco IP Contact Center (IPCC), and the entire line of Cisco IP Communications products, the Cisco IP Communications voice/fax network modules are a cornerstone of Cisco Unified Communications. When used in a Cisco unified communications router with Cisco UCM, Cisco Unified Survivable Remote Site Telephony (SRST), or Cisco UCM Express, the Cisco IP Communications voice/fax network module is a complete IP Communications solution for the business branch.

Figure 1 shows the IP Communications voice/fax network module with one VWIC2-2MFT-T1/E1 and one VIC3-4FXS/DID.

The Cisco IP Communications voice/fax network modules for the Cisco 2800, 2900, 3800, and 3900 Series unified communications routers enable packet voice technologies including VoIP (H.323, Media Gateway Control Protocol [MGCP], and Session Initiation Protocol [SIP]). Cisco Unified Communications solutions provide the means for integrating voice and data within a single network, allowing users to take advantage of services such as IP telephony, integrated services, and toll-bypass while providing an opportunity to improve productivity. By operating on Cisco IOS Software, these solutions incorporate advanced quality-of-service (QoS) features, intelligent network queuing, and standards-based encapsulation, providing efficient direct transport of both voice and fax over IP networks. Cisco IOS Software solutions enable time-sensitive voice traffic to be moved across even low-bandwidth WAN connections with the priority and quality that voice and fax demand. Transporting voice over IP networks continues to provide transport flexibility because IP can be routed across a multitude of WAN technologies (leased lines, Frame Relay, and ATM) along with providing direct connectivity to the desktop.

The 2900 Series and 3900 Series Integrated Services Routers support Network Modules via an adapter (part number SM-NM-ADPTR).

The Cisco IP Communications voice/fax network modules support either one or two Cisco voice interface cards (VICs) or Cisco voice/WAN interface cards (VWICs) and install into network module slots for the Cisco 2800, 2900, 3800, and 3900 series unified communications routers. The Cisco VICs are daughter cards that install into the network modules and provide the interface to the PSTN and to telephony equipment (PBX, key systems, fax machines, phones). The Cisco VWICs are daughter cards that provide the interface to the PBX, PSTN, and/or WAN.

VICs include 2-port foreign exchange station (FXS), direct inward dial (DID), foreign exchange office (FXO), and E&M analog interface cards. Also available are 4-port FXS and 4-port FXO cards and a 2-port ISDN Basic Rate Interface (BRI) digital interface card providing -40V phantom power. These cards cover the entire range of analog connectivity options along with user-side and network-side digital BRI connections (Table 1). Cisco VWICs include 1- and 2-port T1 and E1 interface cards with optional drop-and-insert capability. These cards cover a full range of digital voice and WAN connectivity options and provide connectivity to the world's PBXs, PSTNs, and Post, Telephone, and Telegraph (PTT) organizations.

Cisco IP Communications voice/fax network modules provide the gateway to Cisco Unified Communications for calls to and from the PSTN and the traditional telephony equipment. Users can deploy networks that take advantage of investments in existing telephony equipment while also deploying and integrating IP telephony immediately or in the future. These network modules enable users to operate at any point on the integrated voice, video, and data infrastructure spectrum while incrementally adding connections to both traditional telephony and IP telephony.
