Emergency Transfer Relay Port (Etr); Contact Closure Port (Cca); Implement The Contact Closure Feature; Router Ports (Eth Wan) - Avaya G450 Installing And Upgrading

Emergency Transfer Relay port (ETR)

The ETR port is a standard RJ-45 network port. Use the ETR port to connect to up to two 808A
Emergency Transfer Panels. These panels provide basic telephone services in the event of
system failure.
For more information on Emergency Transfer Relay, see
Transfer Panel and associated telephones on page
For information on installing the 808A Emergency Transfer Panel, see 808A Emergency
Transfer Panel Installation Instructions, which ships with the Emergency Transfer Panel.

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 G450's Contact Closure feature. The Contact Closure feature is a
controllable relay providing dry contacts for various applications.
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 59.

Implement the Contact Closure feature

Connect an Avaya Partner System Contact Closure Adjunct™ box to the CCA port.

Router ports (ETH WAN)

Each ETH WAN port 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 G450 serves as a router for the
WAN.

Switch ports (ETH LAN)

Each ETH LAN port 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.
