Avaya G450 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 S8XXX Server to deliver Communication Manager-based telephony to 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.
