Manufacturer Model Number:VG310

Description: 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).
