- Overview
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.
What's New With This Release
- This is the initial release of the G450 Media Gateway
- 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

- Features
Robust Resiliency Features
- The G450 delivers a variety of voice survivability options to help ensure that the branch can continue to function effectively in the event of network outages. By using an S8300 Server in Local Survivable Processor (LSP) mode, full-featured IP telephony is restored quickly when the WAN link between the main S8XXX Server and the remote G450 is broken. Even without the LSP, the G450 supports Standard Local Survivability, where basic telephony features are available when the WAN link fails. Furthermore, dual, redundant hot-swappable power supplies, and replaceable, hot-swappable main board modules and fan trays ensure help to lower both MTBF and MTBR.
- Helps to maintain business continuity in the event of an unforeseen disruption.
Designed for Deployment Flexibility
- 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.
- G450 can fit into a variety of network environments; enabling standardization and lowering Total Cost of Ownership.
Scalability
- The G450 has the capacity to grow as business needs expand with its modular architecture and capacity for 192 analog or digital endpoints, 8 T1/E1s, 240 DSPs, and 64 announcements. Multiple G450s can be controlled by S8XXX Servers in either ICC or LSP mode.
- Scalable, High Capacity Platform provides Investment Protection
Enhanced Serviceability
- The G450's modular design streamlines serviceability for both customers and field technicians. Fans can be easily 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.
- Enhanced Serviceability lowers Total Cost of Ownership.
Enhanced Security
- 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.

- Reliabilty and Performance
Reliability Overview
When homed back to a central Avaya S8XXX Server running Communication Manager, the G450 can continue to provide basic telephony even if the connection to the centralized server is lost. This capability is called Standard Local Survivability. For more mission-critical applications, the G450 can be configured with a backup server, called a Local Survivable Processor, that provides full-featured telephony when connection to the centralized server is lost. In many circumstances, the failover to either Standard Local Survivability or the Local Survivable Processor is call preserving.
The modem dial-backup feature allows the gateway to reconnect to the centralized Avaya S8XXX Server over a DSL modem facility if the main connection is lost.
Auto fallback allows the gateway to automatically re-connect to the main connection when available after having migrated to a fall-back to eliminate the need to manually reconnect the gateways.
There is extensive routing and switching resiliency built in the G450. Support for industry standard RIPv1, RIPv2, and OSPF (including support for Equal-Cost Multi-Path Routing) routing protocols is included. The G450 also supports the Virtual Router Redundancy Protocol (VRRP) to provide transparent routing redundancy to both data and voice endpoints.
The G450 can connect to an existing office network through its fixed 10/100/1G LAN switch ports.
To allow logical separation of network users, the G450 supports the configuration of up to 64 802.1Q VLANs. 802.1W Rapid Spanning Tree support enhances business-critical and real-time applications by dramatically speeding network response and recovery from link failures from tens of seconds to less than a second. An alternative port redundancy feature provides similar sub-second fail-over feature that is easy to implement and well-suited for branch office environments.
There are several high-resiliency components of the G450 Media Gateway, many of which are field-replaceable. The G450 has an optional second power supply, that can help load balance and provide additional protection against potential hardware failures. The G450 has a removable fan tray to satisfy cooling requirements.
