G350 Media Gateway - Overview
The G350 Media Gateway is a converged networking device that
incorporates a IP Telephony Gateway, an advanced IP WAN router, and a
high-performance LAN switch into a compact modular chassis designed for
industry standard 19” data rack mounts.
The G350 chassis is 3U high and contains six media expansion slots. Five
slots use the same form factor as the G700 Media Gateway, and will
support use of several MM7XX voice media and MM34X IP WAN routing
modules. One of the slots can also house an optional S8300 media server
configured as either an Internal Call Controller (ICC) or a Local
Survivable Processor (LSP). The G350 has one slot for High-Density Media
Modules (HDMM), which provide for cost-effective DCP and PoE telephony
expansion. The G350 also hosts several ports for connectivity for
WAN/LAN, analog, Contact Closure, USB and console access. An Emergency
Transfer Relay (ETR) feature connects the fixed analog trunk port to one
of the fixed analog station ports during a power outage to ensure basic
telephony service for emergency calls to and from the office.
As part of an Avaya Enterprise Connect Solution, the G350 is designed to
network back to a central External Call Controller (ECC), such as the
S8500 or S8700 Media Server. This significantly reduces costs by
enabling the enterprise to design and administer telephony services for
all remote branch office locations from one central location. For
business continuity, the G350 can be configured to register with up to 3
back-up servers if the primary server fails. A local S8300 media server
can also be optionally installed as a Local Survivable Processor (LSP)
to provide enhanced local survivability. The LSP acts as the server of
last resort, taking over telephony controller functions for the G350 if
all other means fail.
