Chapter 8 Features of Other Compatible Cisco Devices
Cisco Voice Gateway 200
The Cisco VG200 chassis can hold a network module (NM) that provides processing and digital signal processor (DSP) resources, and voice interface cards (VICs), which provide the physical voice interfaces. A typical configuration includes an NM-2V network module and two VICs. These VICs can be any combination of Foreign Exchange Station (FXS), Foreign Exchange Office (FXO), ear and mouth (E&M), or Basic Rate Interface (BRI) (both user and network sides), for a total of four ports. Another common configuration of the Cisco VG200 is to use the digital T1/E1 Packet Voice Trunk Network Module that supports up to 60 voice channels (2-E1).
Features
The Cisco VG200 has the following key features:
•Modular architecture—Enables interfaces to be upgraded to accommodate expansion or changes in technology as new services and applications are deployed.
•Ease of administration—Can be managed, controlled, and administered using Cisco CallManager, but can also be accessed directly using the same command-line interface (CLI) as other Cisco IOS software-based products. When used with Cisco CallManager 3.0 or later as a call agent, the
Cisco VG200 functions as a Media Gateway Control Protocol (MGCP) gateway.
•Versatility—Provides a LAN interface to a fast10/100BASE-T Ethernet port, a console port for local access using a terminal, nonvolatile random-access memory (NVRAM) for storing configuration information, and dynamic random-access memory (DRAM) for main memory and shared memory. The Cisco VG200 supports MGCP on its FXS and FXO analog ports, while it supports H.323 on its T1 digital ports.
