About this book
8 Administration for the Avaya G450 Media Gateway

Issue 1 January 2008 9
Chapter 1: Introduction
The Avaya G450 Media Gateway is a multipurpose media gateway that can be deployed in
medium to large sized branch locations or in wiring-closets servicing buildings and floors, in a
campus environment. It works in conjunction with Avaya Communication Manager IP telephony
software running on Avaya S8XXX Servers to help deliver intelligent communications to
enterprises of all sizes.
The G450 combines telephone exchange and data networking, by providing PSTN toll bypass
and routing data and VoIP traffic over the WAN. The G450 features a VoIP engine, an optional
WAN router, and Ethernet LAN connectivity. The G450 provides full support for Avaya IP and
digital telephones, as well as analog devices such as modems, fax machines, and telephones.
The G450 can support up to 450 users when deployed as a branch gateway in a mid to large
branch office of a large enterprise or a call center, and can serve up to 2400 users when
deployed as a campus gateway. Both configurations require Avaya Communication Manager IP
telephony software running on one or more Avaya S8XXX Servers. The 450 user capacity is
reached when the Avaya S8300 server is used and the 2400 user capacity is reached when the
Avaya S8500 Server is used.
Telephone services on a G450 are controlled by an Avaya S8XXX Server operating either as an
External Call Controller (ECC) or as an Internal Call Controller (ICC). The G450 supports the
Avaya S8300 Server as an ICC, or as an ECC when the S8300 is installed in another media
gateway. The G450 also supports the Avaya S8710, S8720, S8730, S8500, and S8400 Servers
as ECCs.
An ICC can be used in addition to an ECC with the ICC installed as a Local Survivable
Processor (LSP) designed to take over call control in the event that the ECC fails or the WAN
link between the branch office and main location breaks. The LSP provides full featured
telephone service survivability for the branch office. The G450 itself also features Standard
Local Survivability (SLS), which provides basic telephone services in the event that the
connection with the primary ECC is lost.
The G450 is a scalable device with a basic configuration consisting of 1 power supply unit
(PSU), 256 MB RAM, and a single DSP childboard supporting either 20 or 80 VoIP channels.
This configuration can be enhanced by adding a redundant PSU, up to two RAM modules of
1 GB each, and up to three additional DSP childboards, increasing the number of VoIP
channels to 240 channels.
