Avaya G350 Media Gateway
Issue 6 February 2007 127
For more information about features of the G350 Media Gateway, see 03-300435, Overview of
the Avaya G250 and G350 Media Gateways.
Configurations
Deployment modes
The G350 is a modular device with multiple configuration possibilities to meet specific individual
needs. Six slots in the G350 chassis house a customized selection of media modules. These
media modules connect to different types of circuit switched phones, trunks and data devices.
One of the slots can house an internal media server. A major configuration option is of which
type of media server to deploy. The media server can be a media module or a stand-alone
device.
The G350 can be deployed in one of two basic working modes:
● Distributed Avaya CM Branch Gateways. In this mode, an external media server controls
the G350. This can be a stand-alone media server, such as the S8500 or the
S8700-series server, or a separate media gateway in a standalone configuration.
The G350 can also house an S8300 Media Server module to function as a Local
Survivable Processor (LSP). This LSP can take over control of the G350 if the external
media server stops serving the G350. For a summary of how the LSP in a G350 works,
see S8300 Media Server in an LSP configuration
on page 37.
● Stand-alone. In this mode, an internally housed S8300 Media Server module controls the
G350. See Avaya S8300 Media Server
on page 29.
Multiple G350s can be deployed in many remote branches of a large organization. Large
branches or main offices can deploy an Avaya G700 Media Gateway, which provides similar
functionality to the G350 for a larger number of users. Up to 50 G350 and G700 Media
Gateways can be controlled by a single S8300 Media Server housed in a G700 Media Gateway.
Up to 250 G350 and G700 Media Gateways can be controlled by a single S8500 or
S8700-series Media Server.
Expanded capacity and multiple G350 gateways in a branch
You can deploy multiple G350 media gateways in branch offices and benefit from increased
capacities and additional configuration options. Beginning with Avaya Communication Manager
release 3.1.X, the advanced mode in Avaya Solution Designer reflects these additional
capacities. The Solution Designer allows you to build a G350 configuration and verify that it
meets system resource limitations.
You can use the G350 media gateway with a S8300B as a primary server for up to five G250 or
G350 media gateways. You can install any combination of media modules. These
configurations are subject to traffic engineering rules. See Table 14:
G350 Capabilities on
page 133 for more information.
