Contact Closure Port (Cca); Router Port (Eth Wan); Switched Poe Ports (Eth Poe Lan); Console Port (Con) - Avaya G250 Installing And Upgrading

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 G250'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
Adjunct on page 47.

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 G250 serves as a router for the WAN.

Switched PoE ports (ETH PoE LAN)

There are eight 10/100BASE-T Power over Ethernet ports for connecting powered end devices
or LAN equipment.
Note:
DCP ports replace these PoE ports on the G250-DCP.
Note:

Console port (CON)

CON is a standard RJ-11 network port. Use the CONSOLE port to connect a console device or
modem to the G250.
