When digital phone extensions are required in another building, additional In-Range Out-Of-Building (IROB) protective
equipment must be used. For phones connected to IP Office
DS
ports, the supported device supplied by ITWLinx is a
towerMAX DS/2 module. This IROB device was previous badged by Avaya as the 146E IROB.

!
WARNING
This device is not supported for TCM port connections, ie. 4100 Series, T-Series, 7400 Series and M-Series phones.
·
Only DS connections on an external expansion module are supported. DS ports on cards in the control unit should
not be used.
The protection device should be installed as per the instructions supplied with the device. The ground points on the IP
Office control unit and the DS modules must be connected to a protective ground using 18AWG wire with a green and
yellow sleeve.
Typically the IROBs 2 RJ45 EQUIPMENT ports are straight through connected to the 2 RJ45 LINE ports. This allows existing
RJ45 structured cabling, using pins 4 and 5, to be used without rewiring for up to two DS connection. However each of
these ports can be used to connect a second extension using pins 3 and 6.
