The Avaya G450 Media Gateway provides a scalable, reliable, and secure platform for delivery of Avaya Communication Manager-based IP telephony applications. It is targeted for mid to large sized branch offices, medium sized standalone businesses, or small campus environments. Like other Avaya GX50 series Media Gateways, it can be configured to extend Communication Manager features and applications to branch offices at the edge of the enterprise network. The G450 can also be configured with an S8300 Server blade or a standalone S8500 Server to deliver Communication Manager-based telephony to standalone or small campus environments.

Description
The Avaya G450 Media Gateway consists of a 3U high, 19" rack mountable chassis with field-removable Supervisor Main Board Module, Power Supplies, Fan Tray, DSP resources and memory. It has eight Media Module slots that host a combination of interface boards to support T1/E1, ISDN-BRI, WAN interfaces, digital or analog telephones and analog trunks. The first Media Module slot can also host an S8300 Server to provide integrated IP Telephony for standalone businesses or mission-critical survivability for branch office-deployed G450s.

Important G450 capabilities include:

• Field-replaceable Main Board Module supports optional DSP and Memory add-ons. Built-in interfaces include two 10/100/1000 Base-T LAN ports, two 10/100 Base-T WAN ports, two USB ports, console and services ports, Contact closure adjunct port, and an ETR port (for emergency calls during power failures)
• Modular DSP Resources are available as daughterboards for Main Board Module. These daughterboards can be implemented in 20 or 80 channel increments. The maximum capacity is 240 channels. Codecs supported include G.711, G.729, and G.726.
• Robust TDM Capabilities for scalability and deployment flexibility including 240 voice channel capacity, 192 analog or digital (DCP) ports, up to 8 T1/E1s* up to 10,000 Busy Hour Call Completions
• High-resiliency features such as dual, redundant, load-sharing power supplies; modular fan tray, standard Local Survivability and Enhanced Local Survivability (with S8300 Server)
• Basic routing capabilities including OSPF, RIP, PPP, Frame Relay and VRRP support. Available IP WAN routing media modules add support for PPP/Frame Relay connectivity over E1/T1 or Universal Serial Port (USP) interfaces. The G450 can also connect to an external WAN device via fixed 10/100 Ethernet WAN router ports, which support traffic shaping to match data transfer rates with available WAN bandwidth.
• Enhanced Quality of Service including Dynamic Call Admission Control for improved bandwidth utilization and Respond Time Report for better WAN monitoring
• Advanced Security including VPN support, SRTP encryption, SSH/SCP, SNMP v3 support, secrets management

Designed as the complementary gateway for S8500/S8700/10/20-based media server solutions, the G650 offer the features, scalability, and system uptime that enterprises require for mission-critical telephony applications.

Business Benefits

• Supports multi-protocol environments where enterprises have a requirement for concurrent support of TDM and IP-based telephony.
• Provides an evolutionary approach to mixed TDM/IP or IP telephony for enterprises with traditional TDM-based infrastructures to provide greater ROI by leveraging their existing investments.
• Provides a standard migration and expansion platform for all existing Avaya TN-style Media Gateways that enables the easy integration of voice and data infrastructure over a standard 19-inch data rack.
• Supports a variety of connectivity and availability options, allowing for easy integration into existing voice networks.
• Support for T.38 Fax and Modem over IP so that non-IP communications can travel over IP telephony links.

FEATURES

• Connectivity Options
• TTY over IP
• T.38 Fax and Modem over IP Support
• Multi-protocol Connectivity
• Gateway Resiliency

Description
The G650 Media Gateway features an 8U high, 14-slot chassis that can be installed in industry standard EIA-310 19", 24", or 600 mm ETSI open or closed racks. The G650 can accommodate a range of analog, digital, ISDN, and IP (over the LAN) phone station configurations, with voice transport options over IP, analog, TDM, or ATM. Available dual redundant, load-sharing power supplies with AC/DC inputs provide enhanced system reliability. For scalability, up to five G650 Media Gateways can be stacked together using a TDM/LAN cable and a built-in connector in the back of the chassis to form a high-capacity port network.

For call control, the G650 Media Gateway connects to an external S8500 or S8700 Media Server over an IP link using the TN2312BP IP Server Interface (IPSI). For mission-critical applications, G650 port networks can be configured for IPSI duplication, which provides fault-tolerant duplicated control paths to the media server. This feature introduces a high-availability option for enterprises with existing mission-critical voice systems that want to migrate to an IP transport solution without compromising system reliability and availability.
