The G350 is designed for use in a 16- to 24-user environment, but can support sites with up to 
40 stations. The G250 media gateway is designed for smaller branch offices with two to eight 
users.
Telephone services on a G250/G350 are controlled by a Media Gateway Controller (MGC). You 
can use a server running Avaya Communication Manager call processing software as an MGC. 
Both the G250 and the G350 integrate seamlessly with Avaya Servers S8700-series, S8500, 
and S8300 to provide the same top quality telephony services to the small branch office as to 
the headquarters of the organization.
The MGC can be located at the headquarters and serve the G250/G350 remotely. The G250/
G350 can optionally house an internal Avaya S8300 Server as a local survivable processor 
(LSP) 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 consists of a 
module built into the G250 itself to provide partial backup MGC functionality in the event that the 
connection with the primary MGC is lost. An additional option is Enhanced Local Survivability 
(ELS). ELS can be provided for both the G250 and the G350 by installing an S8300 Server as 
an LSP, capable of providing full MGC functionality in the event that the connection with the 
primary MGC is lost.
In addition to advanced and comprehensive telephony services, the G350 provides full data 
networking services, precluding the need for a WAN router or LAN switch.
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.
The G250 supports the connection of PCs, LAN switches, IP phones, analog telephones, and 
trunks, using fixed analog and PoE ports on the chassis. A media module slot supports either of 
two WAN media modules, for connection to a WAN. The G250 is available in a special BRI 
model (G250-BRI). The G250-BRI replaces three out of four of the G250’s fixed analog trunk 
ports with two ISDN BRI trunk ports.
