3.1 Attaching TELES.iTA/2TR Box
3.1.1 Attaching Power Supply
First, attach the external power supply to your TELES.iTA/2TR Box by plugging the power
cable into the power jack. Plug the power supply into an electric power outlet.
The TELES.iTA/2TR Box then conducts a diagnostic self-test. During the test each LED will
light up and the red power LED will remain lit.
3.1.2 Attaching Analog Devices
Attach your terminal equipment to the TR ports located at the back of the TELES.iTA/2TR
Box.
In the table below you will find a list of possible connections.
Device Connector Type of Connection
Devices with RJ-11 plugs
(international standard)
Attach your devices directly to the TR ports.
(see figure on page 3)
Devices with other plugs
Purchase an adapter from your local dealer that converts your plug
to a RJ-11.
The figure on the right shows the RJ-11 plug. The letters A and B indicate
the pins that are used. Lift the receiver and check if the LED for that port
lights up. You can attach a maximum of three terminal devices to each
TR port.
3.1.3 Attaching to ISDN
Attach your TELES.iTA/2TR Box to the ISDN line (also known as the BRI or S/T interface)
using the RJ-45 cable provided. To activate the ISDN line, lift the receiver of a telephone at-
tached to the TELES.iTA/2TR Box. The appropriate green port LED should light up and a
dial tone should be heard. If not, there is a problem with the ISDN line or the ISDN cable is
possibly defective (see chapter 6.3).
