Introduction
The Eicon Networks ISDN NT1 is a compact network termination
device for connecting data terminal equipment to an Integrated
Services Digital Network (ISDN).
The NT1 provides an interface port without the need for a specialized
interface cable. You can connect ISDN devices to the NT1 through
two S/T interface ports.
This installation guide describes how to set up the NT1 and connect
your devices to it.
Setting up the ISDN NT1
You can connect up to two ISDN devices —such as an ISDN fax or
phone—to the NT1. However, there are some restrictions on how far
the ISDN devices can be located from the NT1.
• The ISDN devices must be located within 150 meters (500 feet)
of the NT1. Alternatively, you can connect a single device at a
distance of up to 900 meters (3000 feet), but in this case only one
device can be connected.
Follow the instructions below to set up the NT1. Be careful not to
touch any exposed wires.
1 Determine Your Termination Requirements
The ISDN NT1 and your other ISDN devices must be set to a
specific termination value according to:
• how many other ISDN devices you connect to the NT1, and
• the distance of each ISDN device from the NT1.
Table 1 lists all the different ways to set up the NT1 and gives the
termination values required in each case.
Locate the row which exactly matches how you plan to use the
NT1. To help you, an illustration of each row is provided
beginning on page 8, and two examples are given below the table.
You will use the information under the headings “Termination”
and “NT1 Switch Settings” in Step 2.
Note: The table uses metric measurements. The equivalent imperial
measures are: 75 m (250 ft), 150 m (500 ft), 900 m (3000 ft).

Table 1. Determining Termination Settings
2 Set the Required Termination
You must set the NT1 and your ISDN devices to the termination
value indicated by Table 1.
Set the termination on your ISDN devices to the value specified
under “Termination—Other Devices.” The manuals which came
with your ISDN devices can tell you how to do this.
To set the termination on the NT1, you manipulate five small switches
on the rear of the unit, shown in Figure 1, to match the settings given
under the heading “NT1 Switch Settings” in Table 1.

For example, if you determined that row #3 describes how you
will be using the NT1, set switches 1, 3, and 5 to the OFF position
(up), and set switches 2 and 4 to the ON position (down).
Note that these switch settings reflect both the termination value
and the distance of other ISDN devices from the NT1. This is why,
for example, row #2 and row #3 have different switch settings,
even though the NT1 termination value for both is 100 Ω. If you
are interested, an explanation of the specific function of each
switch is given in “Appendix C: Switches,” at the end of this
installation guide.
3 Connect the Power Supply
Plug the power supply into the jack labelled “Power” on the rear
panel of the NT1 (see Figure 1). Plug the other end into the wall
socket.
4 Connect Your ISDN Line
Locate the RJ45-to-RJ11 cable included with the NT1. Plug the
RJ45 end (the larger end of the cable) into the jack labelled “U”
on the rear panel (see Figure 1). Plug the RJ11 end of the cable
into your ISDN wall outlet..

Connect the ISDN Device to a port labelled “S/T.” Connect your
other ISDN devices to the remaining port labelled “S/T.”
The Eicon NT1 and all the devices you connected to it should now
be fully functional. The next section, “Understanding the Signal
Lights,” explains how to interpret the diagnostic signal lights
while using the NT1.

The three lights (LEDs) on the front panel of the NT1 provide
information about the status of the NT1 and the ISDN line.
