Introduction; Setting Up The Isdn Nt1 - Eicon Networks ISDN NT1 Installation Manual

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.
