Avaya G250 Media Gateway

The Avaya G250 Media Gateway is an enterprise branch office gateway designed to serve the communications needs of a small branch with 2 to 12 extensions.This gateway allowsorganizations to economically extend their headquartercommunication applicationssuch as the Avaya Communication Manager and the Avaya Modular Messaging out to their branch locations to achieve lower overall costs and increased collaboration across their entire organization.

This is a powerful branch communication solution that packs an IP telephony gateway, an advanced IP WAN router, and a high-performance LAN switch into a compact, 2U high 19" rack mount unit.The Avaya G250 Media Gateway extends the enterprise communications capabilitiesin the headquarters location out to a branch location and is ideally suited for branch locations needing from 2 to 12 extensions. The system gains its functionality from a centralized Avaya Media Server running Avaya Communication Manager, but has several survivability options that allowcommunications to continue operating even ifthe connection to the main server is lost for any reason.

An advanced TDM/IP architecture provides seamless connectivity and communications between a wide variety of analog, digital, H.323, and SIP-based IP telephony devices and applications. To enhance security, the Avaya G250 Media Gateway can secure VoIP media streams using Advanced Encryption Standard (AES), approved for use by U.S. Government agencies to protect sensitive information.

The Avaya G250 Media Gateway also functions as an edge router to support the consolidation of voice and data traffic over an IP network.OptionalIP WAN routing media modules add support for PPP/Frame Relay connectivity over E1/T1 or Universal Serial Port (USP) interfaces. The G250 media gateway can also connect to an external WAN device via a fixed 10/100 Ethernet WAN router port, which supports traffic shaping to match data transfer rates with available WAN bandwidth.

• Headquarters Communications Extended to the Branch: The G250 allows enterprises to extend their enterprise communications applications out to their branch office locations to facilitate productivity and collaboration at the branch offices.
• Communications Continuity: The gateway provides branch office users with a highly resilient system that continues to provide communications capability even if the connection between the office and primary headquarters is lost.
• Converged All-in-One Unit: The G250 integrates telephony, routing, and data switching into one box, reducing the overhead and complexity of managing disparate gateways, routers, and switches.
• Centralized Applications Management: The resources required to manage branch communications are significantly reduced as the gateway extends a single centralized set of communications applications to the branch.
• Automatic Re-connect: The gateway can be administered to automatically reconnect to the primary media gateway controller when available if after going into a backup mode.
• Emergency Transfer Relay: An Emergency Transfer Relay (ETR) feature allows emergency calls even in the event of power ailure.
• Remote Deployment and Management: The G250 is easily installed and remotely configured by a central support staff, allowing the enterprise to get branch offices operational quickly and cost-effectively.
