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.

Select the termination setting using these switches

Connect your ISDN wall socket to this port

Eicon Network Termination (NT1) Installation Guide 5

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..

S/T Ports Signal Lights

Figure 2. Front Panel

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.

Understanding the Signal Lights

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