Avaya G450 Media Gateway

The Avaya G450 Media Gateway provides a secure, reliable, and scalable platform for the delivery of Avaya Communication Manager-based IP telephony applications. It is targeted to 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.

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, 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, and 64 announcements.
- 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.
- The G450 is interoperable with other Avaya Media Gateways and can be used in either the main headquarters location (with an S8300 or S8500 Server running Communication Manager) or a mid to large branch office networked back to a central S8XXX Server.
The G450’s modular design streamlines serviceability for both customers and field technicians. Fans can be eas- ily replaced, DSPs and RAM easily added, supervisor modules swapped out, power supplies changed. Given that all media modules, main board modules, power supplies and fan trays are hot-swappable; downtime is minimized.
The G450, like other GX50 Media Gateways, helps to encrypt voice traffic and signaling over the IP network to prevent eavesdropping. In addition, the G450 supports advanced security features such as comprehensive secrets management, SSH/SCP and SMNP v3 so network managers can securely configure and manage the G450.
