Chapter 1: Introduction
The Avaya Branch Gateways (Avaya G250 and G350 Media Gateways) form part of Avaya
Enterprise Connect, Avaya’s solution for extending communication capabilities from the
headquarters of an organization to all collaborative branch locations. Avaya Enterprise Connect
helps you provide the same high quality services to all organization members, regardless of
their location.
The Branch Gateways are high-performance converged telephony and networking devices that
are located in small branch locations, providing all infrastructure needs in one box — telephone
exchange and data networking. The Branch Gateways each feature a VoIP engine, WAN router,
and Power over Ethernet LAN switch. The G350 provides full support for legacy IP, DCP, and
analog telephones. The G250 supports legacy IP and analog telephones. In addition, the
G250-DCP model supports DCP telephones.
The G350 is designed for use in an eight to 40 user environment, aimed at branch offices with
16 to 24 stations. The G250 is designed for use in a two to 12 user environment, aimed at small
branch offices with two to eight stations.
Telephone services on a Branch Gateway are controlled by a Media Gateway Controller (MGC).
You can use a media server running Avaya Communication Manager (CM) call processing
software as an MGC. Both the gateways integrate seamlessly with Avaya Media Servers
S8700, S8710, S8720, S8500, S8400, and S8300 to provide the same top quality telephony
services to the small branch office as to the headquarters of the organization.
The Branch Gateways can subtend to an MGC located at the headquarters or the MGC can be
installed locally. The Branch Gateways can optionally house an internal Avaya S8300 media
server for Enhanced Local Survivability (ELS), providing full MGC functionality in the event that
the connection with the primary MGC is lost, or as the primary MGC for standalone deployment.
When the primary MGC is located at a remote location, the G250 features Standard Local
Survivability (SLS). SLS provides partial backup MGC functionality in the event that the
connection with the primary MGC is lost.
In addition to advanced and comprehensive telephony services, the Branch Gateways provide
full data networking services, precluding the need for a WAN router or LAN switch.
Avaya G350 Media Gateway Overview
The G350 is a modular device, adaptable to support different combinations of endpoint devices.
Pluggable media modules provide interfaces for different types of telephones and trunks. A
combination is selected to suit the needs of the branch. A LAN media module with PoE
standard compliant Ethernet ports provides support for IP telephones as well as all other types
of data devices. A range of telephony modules provides full support for legacy equipment such
as analog and digital telephones.

Introduction
12 Overview for the Avaya G250 and Avaya G350 Media Gateways
Avaya G250 Media Gateway Overview
The G250 supports the connection of PCs, LAN switches, IP telephones, analog telephones,

Issue 2 February 2006 15
The MM316 and MM716 are compatible with Avaya CM version 2.0 and higher, and G350
firmware version 25.0.0 and higher.
Versions of the MM314 LAN media module with Material Code 700384 (C/S:2.0) also require
Avaya CM version 2.0 and higher, and G350 firmware version 25.0.0 and higher.
Branch Gateway feature enhancements
The Avaya G250 Media Gateway and the Avaya G350 Media Gateway for Avaya CM Release
3.1 include the same functionality that was provided in Release 3.0, and offer the following new
or enhanced capabilities. These capabilities are available for both the G250 and the G350,
except where otherwise specified.
SLS survivability enhancements (G250 only)
SLS is a configurable software module that allows a local G250 to provide a limited amount of
MGC functionality when no link is available to the server, an LSP, or an Enterprise Survivable
Server (ESS). SLS was first introduced in Release 3.0, and has been enhanced as follows:
●Supported for the G250-BRI analog interfaces
●Supported for the G250-DCP analog and DCP interfaces
●Supported for the G250-DS1 analog interfaces
●Addition of the following SLS features:
●Phone displays
●Multiple call appearances
●DID support
●Call holding support
●Call transfer support
●IP Softphone support
●Inter-digit timers during digit collection
●TUI access to the contact closure
VPN enhancements
Several enhancements to the G250/G350’s VPN capabilities have been implemented in
Release 3.1, including:
●Support for configurations in which the G250/G350 acts as a regional VPN hub for
dynamically addressed peers
●Enhanced failover scheme for switching back to the primary peer after timeout

Introduction
16 Overview for the Avaya G250 and Avaya G350 Media Gateways
●Support for filtering by protocol and port ranges in crypto list bypass rules
●Increased configuration capacities, as required for PIM support
●Interoperability with SonicWALL, Avaya IP office, and Avaya G150 Media Gateway
●Ability to generate Remote Security Services (RSS) notifications when an Unauthenticated
Access Event occurs (refer to RSS notifications on page 17)
USB port supported in G250
All models of the G250 now support the USB port for use with the Multitech MultiModemUSB
MT5634ZBA-USB-V92 USB modem.
Traceroute enhancements
Traceroute is a well-known TCP/IP utility that helps system administrators to troubleshoot
connectivity problems by enabling them to see the route packets are taking to a particular host.
Traceroute does this by displaying the hops along the path.
Release 3.1 improves the G250/G350’s traceroute feature by extending traceroute to the GRE
and ESP tunneling protocols, and to VMON.
SAA and object tracking enhancements
Several SAA and object tracking enhancements have been added in Release 3.1, including the
ability to monitor the states of the following routes: static routes, the DHCP client default route,
and PBR next hops.
IP header compression enhancements
In Release 3.1, IP header compression support has been added for non-IETF Frame Relay
encapsulation.
Port-based network access control (IEEE 802.1x) enhancements
In order to support 802.1x for Avaya IP phones and PCs connected to each port, 802.1x support
has been expanded to include multi-supplicant mode per port, with MAC-based authentication.
The administrator can configure port mode as multi-supplicant or single. For purposes of
backward compatibility, single is the default mode. EAP authentication has also been extended
to support PEAP, TTLS, and TLS types, in addition to MD5.
Frame relay encapsulation enhancements
Frame relay encapsulation has been expanded in Release 3.1 to support non-IETF frame relay
encapsulation.

What’s new in release 3.1
Issue 2 February 2006 17
Caller ID on call waiting support for MM711, MM714, and MM716
The MM711, MM714, and MM716 analog media modules now support Calling Identity Delivery
on Call Waiting (CIDCW). This feature provides visual information on an incoming call while the
called party is on an existing call. This combines the functionality of Call Waiting (CW) and
Calling Identity Delivery (CID).
RSS notifications
The G250/G350 identifies predefined or custom-defined traffic patterns as suspected DoS
attacks and generates SNMP notifications, referred to as Remote Security Services (RSS)
notifications. RSS notifications are intercepted and forwarded to the Security Operations Center
(SOC), where Avaya service representatives respond as necessary to any DoS attacks or
related security issues.
Secure file transfer for announcements
The G250/G350 supports secure transfer of announcement files via SCP to and from the Voice
Announcement Manager (VAL Manager).
