4.9.4 ETR Port
ETR (Enhanced Tip and Ring) ports are provided by the ETR6 base card. They can be used for the connection of DTMF
analog phone devices and Avaya ETR phones.
4.9.5 Expansion Port
This type of port is found on the rear of IP 500v2 control units and external expansion modules. It is used for connecting
the external expansion modules to the parent control unit.
The connection between these ports should only be done using an Avaya Expansion Interconnect Cable. No other cable
type should be used.
Expansion Interconnect Cable
The Expansion Interconnect cable is used to link expansion ports between the control unit and external expansion
module.
·
Supply: One cable is normally supplied with each external expansion module.
· Part number: 1m (3'3") Blue cable - 700213457, 2m (6'6") Yellow cable - 700472871.
4.9.6 EXT O/P Port
The Essential Edition - PARTNER® Version control unit is equipped with a EXT O/P port. The port is marked as EXT O/P
and is located on the back of the control unit adjacent to the power supply input socket and uses a standard 3.5mm
stereo jack plug for connection.
The port can be used to control up to two external devices such as door entry relay switches. The usual application for
these switches is to activate relays on door entry systems. However, as long as the criteria for maximum current, voltage
and if necessary protection are met, the switches can be used for other applications.
The IP Office is able to open (high resistance), close (low resistance) or pulse (close for 5 seconds and then open) the
two switches within the port.
· CAUTION: In installations where this port is connected to a device external to the building, connection must be via a
towerMAX SCL/8 Surge Protector and a protective ground connection must be provided on the IP Office control unit.
The towerMAX range of devices are supplied by ITWLinx (
http://www.itwlinx.com ).
