Analog telephone ports and LEDs
The analog telephone ports are standard RJ-11 telephone network ports.
•
TRUNK is a trunk port.
•
The two LINE ports (ports 2 and 3) are analog telephone ports.
The analog telephone port LEDs show the status of the analog telephone ports.
The following table shows the meaning of the analog telephone LEDs when they are lit:
Contact closure port (CCA)
The contact closure port (CCA) is wired as an RJ-14 port, but uses an RJ-45 network jack. This port is
used to support the G350’s Contact Closure feature. The Contact Closure feature is a controllable relay
providing dry contacts for various applications. To implement the Contact Closure feature, connect an
Avaya Partner System Contact Closure Adjunct
™
box to the CCA port. The adjunct box provides two
contact closures that can be operated in either a normally closed or normally open state. The contact
closures can control devices such as devices that automatically lock or unlock doors or voice recording
units. The CCA port can be configured so that the connected devices can be controlled by an end device,
such as a telephone. For example, a user can unlock a door by keying a sequence into a telephone keypad.
For more information on Contact Closure, see Installation of the Avaya G350 Media Gateway,
555-245-104.
Router port (ETH WAN)
ETH WAN is a standard RJ-45 network port. Use ETH WAN to connect a data device to the internal
router through a 10/100 mbps Ethernet port. The G350 serves as a router for the WAN.
Switch port (ETH LAN)
ETH LAN is a standard RJ-45 network port. Use ETH LAN to connect a data device to the switch
through a 10/100 mbps Ethernet port. You can connect an external LAN to ETH LAN.

G350 or if the G350 becomes unregistered from its
Media Gateway Controller (MGC).
