Connecting the trunk
This section explains how to connect a trunk to the Avaya G350 Media Gateway. There are some
differences in how to connect a trunk, depending on the type of trunk you are connecting. This section
provides separate instructions for connecting various types of trunks, as follows:
•
Connecting an analog trunk
•
Connecting an ISDN BRI trunk
•
Connecting an E1/T1 trunk
Connecting an analog trunk
To connect an analog trunk, plug the trunk line into an analog trunk port on the Avaya G350 Media
Gateway. The Avaya G350 Media Gateway front panel contains an analog trunk port. This port is marked
TRUNK. Use an RJ-11 cable to connect the trunk to the port.
NOTE:
The TRUNK analog telephone port on the G350 front panel forms a mechanical analog
relay with the LINE port next to it. This relay can be configured to provide emergency
transferred telephone service in case of a power outage or disconnection from an external
media server. The TRUNK port is usually used in this emergency scenario to channel all
incoming calls to LINE and to send all outgoing calls from LINE to an outside line.
In addition, the following Avaya media modules contain analog trunk ports:
•
Avaya MM711 — contains eight analog ports that you can use for either telephone and fax lines
or trunk lines.
•
Avaya MM714 — contains four analog line ports and four analog trunk ports.
If you do not have either of these modules, and the analog trunk port on the front panel of the Avaya
G350 Media Gateway is already in use, you must install at least one of these modules in order to add an
analog trunk. See
Adding a media module
on page 51.
Connecting an ISDN BRI trunk
To connect an ISDN BRI trunk, plug the trunk line into an ISDN BRI port on the Avaya G350 Media
Gateway. Use an RJ-11 cable to connect the trunk to the port.
The following Avaya media modules contain ISDN BRI ports:
•
Avaya MM720 — contains eight ISDN BRI ports.
•
Avaya MM722 — contains two ISDN BRI ports.
NOTE:
In the US, you need to connect a separately purchased NT1 device to each ISDN port you
use to connect an ISDN BRI trunk.
