The Cisco® VG350, VG320, VG310, VG204XM, and VG202XM Analog Voice Gateways allow you to use your IP telephony solution with traditional analog devices while taking advantage of the productivity afforded by IP infrastructure.

Unified communications enables organizations to collaborate more effectively and streamline business processes. Reach the right resource the first time. Improve productivity and profitability. Even in an IP world, however, many organizations still use analog devices such as phones, faxes, and modems, and want or need to continue to after migration to IP telephony. Important use cases for analog gateways include:

Budget constraints during migration to unified communications: You don’t have to replace your entire phone system as you move to unified communications. Cisco VG Series Gateways help you migrate at your own pace and budget: you can enjoy the benefits of unified communications and still use your existing analog devices.

Meeting regulatory requirements: Many countries or industry markets require analog devices in certain use cases. Using Cisco VG Series, these organizations can still meet regulatory requirements but also have the benefits of unified communications.

Environments that require phone service but do not have power and require long loop lengths: Examples include ranger stations, phones along railroad tracks, and some military deployments such as remote outposts.

Harsh environments: Industries such as mining and manufacturing have harsh environments in which analog phones often have better endurance.

Requirements for lighter IT infrastructure: Analog phones need fewer switch ports and have no power requirements.

The Cisco VG Series Analog Voice Gateways are Cisco IOS® Software-based (Figures 1 through 3). The Cisco VG350 is a high-density 160-port gateway, the Cisco VG320 is a 48-port gateway, the Cisco VG310 is a 24-port gateway, and the Cisco VG204XM and VG202XM are low-density 4- and 2-port gateways, respectively. These gateways connect analog phones, fax machines, modems, and speakerphones to an enterprise IP voice system, so you can use them as extensions to your Cisco or third-party IP call-control system. Having these devices tightly integrated with the IP-based phone system is advantageous for increased manageability, scalability, and cost-effectiveness. The Cisco VG Series supports high to low concentrations of analog voice ports for modem calls, fax calls, and analog supplementary services.

The Cisco VG350 is built on the Cisco 3945 Integrated Services Router (ISR) powered by high-performance multicore processors. In this platform, you can achieve power redundancy by installing an optional integrated redundant power supply (RPS), which helps decrease network downtime and protects the network from power-supply failures. The VG320 and VG310 are built on the Cisco 2901 platform, powered by a single high-performance core processor. They provide high availability during power failure through an external universal power supply (UPS).

The Cisco VG350, VG320, and VG310 offer 19-inch rack-mount chassis, and the Cisco VG204XM and VG202XM offer desktop form-factor chasses with a fanless design.

Features and Benefits

Familiar Cisco IOS Software-based hardware: The hardware includes uniform Cisco command-line interface (CLI) and Simple Network Management Protocol Version 3 (SNMPv3) support for ease of gateway configuration and operation.

Robust voice quality: Cisco experience in providing toll-quality packet-voice service helps ensure that the Cisco VG350, VG320, VG310, VG204XM, and VG202XM provide the clear, robust voice quality end users have come to expect from telephony services.

Low- to high-density solutions: With solutions from 2 to 160 ports, organizations can have the right-size platform for the right-size deployment.

The VG310 and VG320 can support foreign exchange office (FXO), foreign exchange station (FXS), T1/E1 Primary Rate Interface (PRI), channel associated signaling (CAS), and Basic Rate Interface (BRI) 2- and 3-port voice interface cards (Cisco VIC2 and VIC3, respectively).

Cisco EnergyWise® support: Lower per-port power consumption is supported on the VG350.

Support for long loop lengths: Loop lengths up to 30,000 ft (9,144m) are supported.

Interoperability: Cisco VG Series works with Cisco and third-party IP private branch exchanges (PBXs).

High availability: With these gateways you will experience less voice downtime due to WAN link failure. The Cisco VG Series has built-in Media Gateway Control Protocol (MGCP) failover to an H.323 connection to a Survivable Remote Site Telephony (SRST) router. This failover maintains voice service for analog endpoints if the WAN link fails or you lose connectivity to the Cisco Unified Communications Manager, Cisco Business Edition, or Cisco Hosted Collabortion Solution (HCS). Figure 4 shows integration of the Cisco VG Gateway with Cisco Unified Communications Manager.

Analog Phone Connectivity

The Cisco VG Series is ideal for analog phone deployments ranging from centralized to sparsely concentrated or distributed topologies. These analog voice gateways provide a high level of availability at locations with MGCP fallback, with ease of manageability using Cisco IOS Software monitoring features. They offer many supplementary analog calling features depending on the call control and signaling type used. Refer to Table 1 for the supplementary analog calling features available.

The Cisco VG Series also supports feature access codes (FACs) for invoking supplementary services.

Fax and Modem Connectivity

The Cisco VG Series supports fax machines and modems. When using fax machines, the gateways support Cisco Fax Relay, T.38 fax relay, and fax pass-through. Cisco and T.38 fax relay technologies allow transfer of faxes across the network with high reliability using less bandwidth than a voice call. All modems can be connected to the Cisco VG Series and are transferred over the network using modem pass-through.
