Product Overview

Welcome to the world of ISDN communications. You have acquired one of the finest ISDN terminal adapters
(TAs) available today, the MultiModemISDN from Multi-Tech Systems.

The proliferation of PCs and LANs with bandwidth-intensive applications has generated a powerful demand for
high-speed connections. The worldwide standardization of ISDN, combined in many countries with its growing
availability and falling cost, make it a natural choice for enhancing data throughput. Terminal adapters provide
high-performance solutions for Internet access, file transfer, remote access service (RAS), and running
existing modem applications through the ISDN network.

Product Description

The MT128ISA and MT128PCI are internal PC cards for IBM personal computers; and fit into a full-or half­sized expansion slot. There are two ISDN interface options, ST and U. If you purchased the ST interface
adapter (MT128PCI-SD/SV), you need an ISDN NT1device connection to the ISDN switch. If you purchased
the U interface adapter (MT128ISA-UV), it can directly connect to the ISDN switch (figure 1-1).

Figure 1-1. ST and U Interface Options

Your internal ISDN PC card is compatible with prevalent ISDN switch protocols. It communicates using ISDN
BRI (2B+D) service, which provides up to 128K bps data communications.

This manual documents the following models:

 MT128PCI-SD for ST interface no POTS port
 MT128PCI-SV for ST interface with one POTS port
 MT128ISA-UV for U interface with one POTS port

All of the current analog devices, including telephone set, G3 fax, answering machine, modem, and PBX trunk

Chapter 2 - Installation

Introduction

This chapter describes how to make all the physical and software driver connections necessary for your
terminal adapter to operate in an ISDN environment. Please check the package contents list in Chapter 1
before beginning your installation.

ISDN BRI Line

Before running the ISDN adapter, you need to get an ISDN BRI (Basic Rate Interface) line from your local
telephone company. Your ISDN service provider will provide information to you about the ISDN central switch
type, pertinent subscriber information and SPID (Service Profile ID) number(s).

SPID (Service Profile ID)

The Service Profile ID (SPID) is applicable in the U.S. only. SPIDs are a series of numbers that inform the
central office switch which services and features to provide to an ISDN device. The generic SPID format
comprises 14 digits. The first 10 digits are the main telephone number on the terminal. The last 4 digits are
dependent on the number of terminals on the interface and the services they support.

NT1 Connection

An ISDN Basic Rate (BRI) U-Loop consists of 2 conductors from the CO (telephone company central office) to
the customer premises. The equipment on both sides of the U-loop has been designed to deal with the long
length of the U-loop and the noisy environment it operates in. At the customer premises the U-loop is termi­nated by an NT1 (network termination 1) device. An NT1 is a device which provides an interface between the
two-wire twisted-pairs used by telephone companies in their ISDN BRI network and an end-users four wire
terminal equipment. The NT1 drives an S/T-bus which is usually made up of 4 wires, but in some cases may
be 6 or 8 wires.

The name of the S/T bus comes from the letters used in the ISDN specifications to refer to two reference
points, S and T. Point T refers to the connection between the NT1 device and customer supplied equipment.
Terminals can connect directly to NT1 at point T, or there may be a PBX (private branch exchange, i.e. a
customer-owned telephone exchange). When a PBX is present, point S refers to the connection between the
PBX and the terminal. Note that in ISDN terminology, terminal can mean any sort of end-user ISDN devices,
such as data terminals, telephones, FAX machines, etc. The diagram which follows reflects interface points in
a typical ISDN network.

If your ISDN product operates with a S/T outlet interface, you need an NT1 device to connect to the ISDN
switch. MT128PCI-SD/SV adapters need an NT1 device to connect to the ISDN switch, but the MT128ISA-UV
adapter does not require NT1 device. In the UK, and in many European countries, an NT1 device is supplied
by your telephone company.

Chapter 2 - Installation

Internet Access

If you want to use an ISDN adapter to connect to the Internet, you must get an Internet access account from
an ISP (Internet Service Provider) in your country. You must also confirm with your ISP that they support either
single channel ISDN (64K) or multilinked channel (128K) access.

Safety Warnings

1. Never install telephone wiring during a lighting storm.

2. Never install telephone jacks in wet locations unless the jack is specifically designed for

wet locations.

3. This product is to be used with UL and cUL listed computers.

4. Never touch uninsulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

5. Use caution when installing or modifying telephone lines.

6. Avoid using a telephone (other than a cordless type) during an electrical storm. There

may be a remote risk of electrical shock from lightning.

7. Do not use the telephone to report a gas leak in the vicinity of the leak.

8. To reduce the risk of fire, use only No. 26 AWG or larger Telecommunication line cord.

9. Ports that connect to other apparatus are defined as SELV. To ensure conformity wtih EN

41003, ensure that these ports connect only to the same type of port on the other appara-

tus.

Environment Setup

All ISDN adapter models are Plug and Play (PnP) compatible. Even if the BIOS or computer main board does
not provide PnP feature support, the device driver still can automatically configure the ISDN card with the
proper I/O addresses and IRQ number.

MT128ISA/PCI

Hardware Installation

Note: Disregard step 1 for models MT128ISA-UV only, and proceed to step 2.

1. The ISDN S/T interface can support up to 8 ISDN terminals and NT1 device connecting to

the ISDN network. Only one ISDN S/T device should have the terminator enabled.

Normally, the ISDN terminal farthest from NT1 should have the terminator enabled.

Models MT128PCI-SD/SV and MT128ISA-UV provide two jumpers (JP1 and JP2) for the

terminator setup. The default setting for the adapter(s) is terminator enabled. If there are

other ISDN devices connected to the NT1 with ISDN adapter(s), and you do not require

your adapter as a terminator, remove the JP1 and JP2 shorting plugs (open circuit).
