12 Overview for the Avaya G250 and Avaya G350 Media Gateways
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.
Avaya G250 Media Gateway Overview
The G250 supports the connection of PCs, LAN switches, IP telephones, analog telephones,
and trunks, via fixed analog and PoE ports on the chassis. A media module slot supports either
of two WAN media modules, for connection to a WAN. There are several models of the G250,
with various port combinations for support of analog, BRI, or T1/E1 trunks or DCP telephones,
as described below.
The G250 is available in the following models:
● Analog model (G250-Analog). The G250-Analog includes four analog trunk ports, two
analog line ports, a Fast Ethernet WAN port, and eight PoE LAN ports.
● BRI model (G250-BRI). The G250-BRI includes two ISDN BRI trunk ports, one analog
trunk port, two analog line ports, a Fast Ethernet WAN port, and eight PoE LAN ports.
● DCP model (G250-DCP). The G250-DCP provides twelve DCP (Digital Communications
Protocol) ports, as well as four analog trunk ports, two analog line ports, a Fast Ethernet
WAN port, and two LAN ports.
● DS1 model (G250-DS1). The G250-DS1 provides a T1/E1 and a PRI trunk port, enabling
support of fractional T1/E1 and PRI. The G250-DS1 also includes one analog trunk port,
two analog line ports, a Fast Ethernet WAN port, and eight PoE LAN ports.
