The Branch Gateway G450 is a multipurpose gateway that can be deployed in medium to
large sized branch locations or in wiring-closets servicing buildings and floors, in a campus
environment.
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. This requires Avaya Aura® Communication Manager IP telephony software running on one or more Avaya servers. The Avaya S8300 servers
support 50 Branch Gateways and other Avaya servers support up to 250 Branch Gateways.
Branch Gateway G450 functions
Works in conjunction with Avaya Aura® Communication Manager IP telephony software running on Avaya Servers to help deliver intelligent communications to enterprises of all sizes
- Combines telephone exchange and data networking, by providing PSTN toll bypass, and routing data and VoIP traffic over the WAN
- Features a VoIP engine, an optional WAN router, and Ethernet LAN connectivity.
- Provides full support for Avaya IP and digital telephones, as well as analog devices such as
modems, fax machines, and telephones.
Telephone services on a Branch Gateway are controlled by an Avaya Server operating either as an
External Call Controller (ECC) or as an Internal Call Controller (ICC). The Branch Gateway
supports:
The Avaya S8300 Server as an ICC, or as an ECC when the S8300 is installed in another
Branch Gateway
An ICC can be used in addition to an ECC with the ICC installed as a Survivable Remote Server
(SRS) 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 SRS provides full featured telephone service
survivability for the branch office. The Branch Gateway also features Standard Local Survivability
(SLS) (IPv4 only), which provides basic telephone services in the event that the connection with the primary ECC is lost.
