About This Guide 5
About This Guide
This manual is a guide for the installation of:
•the integrated ISDN Terminal Adapter with built-in V.34
Faxmodem, referred to hereafter as the TA/V.34—for data, voice,
and fax connections;
•and the Terminal Adapter, referred to hereafter as the TA—for data
and voice connections.
Note Because this Owner’s Manual supports two products, some
sections apply only to the TA/V.34 or TA functions.
Product differences are noted throughout the manual.
Once you have successfully installed the TA/V.34 or TA in your IBM
PC-compatible computer, virtually all access to the data, voice (and fax
for the TA/V.34), and other product features is through easy-to-use
point-and-click software included with this product.
This guide is organized as follows:
Introduction (Chapter 1) describes the products and their features and
the technology behind ISDN. It also provides a brief explanation of how
you can take full advantage of the products’ high-speed digital
capability.
Installation (Chapter 2) lists the items required for installation and
explains installation and configuration.
Configuration (Chapter 3) provides tips for setting up your software
and describes how to use the products on ISDN lines.
Problems and Solutions (Chapter 4) provides troubleshooting
information.
The Appendixes provide additional information for a number of topics
including setting up ISDN switches and product specifications.
Documentation Conventions
•Commands to be entered from your keyboard and command
examples described in this guide appear in bold type. For example:
To reset the ISDN card, type ATZ and press Enter.

•The letter “O” is always shown in lower case (o or o) in a command
line. The number zero is always shown as “0.”

Chapter 1 Introduction 7
Chapter 1 Introduction
Congratulations! You have purchased an
advanced, flexible product, the TA/V.34 or TA,
which incorporates the latest high-speed digital telecommunications
technology.
Both the TA/V.34 and TA support ISDN operation up to 128 Kbps and
include a handset port for voice calls over ISDN.
The products are “Plug and Play” (PnP) compatible for use with
Windows 95 and Windows NT 4.0 or higher, and software configurable
for Windows 3.1 or 3.11.
Note You must be running Windows NT version 4.0 or higher and
a Plug and Play (PnP) BIOS in order to use the ISDN
TA/V.34 or TA under Windows NT. To find out whether you
have a PnP BIOS, look for a PnP version number during
startup or refer to your computer documentation. You must
also install a special PnP driver from your NT installation CD.
See Chapter 2.
TA/V.34 and TA Features
These products both include:
•On-board 16550 UART with local RAM buffers and support for 7
interrupts.
•Standards-based implementation through support of standard
protocols: V.110, V.120 Rate Adaptation up to 64 Kbps, X.75
protocol at 64 Kbps (not available in North America), Point-to-
Point Protocol (PPP) at 64 Kbps, and Multilink PPP at 128 Kbps
using two B-channels.
•Built-in telephone handset support for making or receiving voice
calls over an ISDN line.
•Plug and Play support for Windows 95, PORTWIZ software card
configuration for Windows 3.1 and 3.11 systems, and Windows

8TA/V.34 and TA Owner’s Manual
•Installation and configuration software that simplifies ISDN setup
and diagnostics.
•Simultaneous voice and data connections over two channels.
You may also have received an optional standard voice handset with
connecting cord.
The TA/V.34 also includes:
•An ISDN terminal adapter with integrated full-featured V.34
faxmodem on one card.
•33.6 Kbps faxmodem support over digital ISDN phone service, to
allow connection to analog modems, faxmodems, and fax
machines.
Using the TA/V.34 or TA with ISDN
The TA/V.34 and TA are very flexible thanks to the combination of
ISDN and voice capabilities. This means that both devices can
communicate with a wide variety of analog and digital devices while
connected to a digital ISDN line.
Over an ISDN line, you can connect to ISDN sites at 64Kbps, or at 128
Kbps by using both B-channels. Voice calls can be placed or received
over ISDN lines using a handset.
Note The TA/V.34 can connect to an analog modem at up to 33.6
Kbps. The TA/V.34 also connects to a fax device, such as a
fax machine or faxmodem, at speeds up to 14.4 Kbps.
With two ISDN channels, you can also make a voice call and a data
call simultaneously. Additionally, with the TA/V.34 you can make a
voice call and a fax call, or a data call and a fax call simultaneously.
Ordering ISDN Service
To use ISDN, you must contact your local telephone company to get the
service started. ISDN service is connected through standard phone
wires, just like ordinary analog service.
The TA/V.34 or TA you have purchased connects to the telephone
company’s ISDN service through a Network Termination 1 (NT1)
device. In many European countries, the telephone company installs an

Chapter 1 Introduction 9
NT1 device when you order ISDN service. The NT1 typically has from
one to eight connections through something called an S/T bus, which
provides a physical connection point to ISDN equipment such as the
TA/V.34 or TA, ISDN telephones, and so on. The TA/V.34 or TA has a
built-in S/T interface for connection to the NT1 device.
If you are connecting via a Private Branch Exchange (PBX), there is a
Network Termination 2 (NT2) device that is part of your PBX
equipment and serves the same function as the NT1 device; contact
your PBX vendor for details.
Setting Up Phone Numbers
The TA/V.34 or TA you have purchased has multiple functions. For
example, the TA has data capabilities as well as voice capabilities.
Both the ISDN line and the TA need to be configured to distinguish
between the two capabilities. This distinction is made by requiring
different phone numbers, one for each capability.
The configuration varies depending on where the ISDN product will be
installed. But regardless of where the installation will take place, there
are two basic options to choose from.
One option is to have multiple numbers, called Directory Numbers
(DNs), one for each device or capability. This is typically referred to as
Multiple Subscriber Numbers (MSNs). The other option is for various
devices on the line to share a single Directory Number, with an
extension number, or “SubAddress,” for each.
Using Multiple Subscriber Numbers
If you are in North America, this is the option you should choose to set
up your ISDN product (TA or TA/V.34). We have made it very simple
for you to request this service by setting up an order package that is
designed to work with your new ISDN product. It is called the ISDN
Order Code or IOC. For more details about the IOC, please refer to the
Service Installation flyer included with your package.
If you are installing an ISDN line outside of North America, we
recommend that you take advantage of the multiple subscriber numbers
by simply ordering your ISDN line with the MSN option, if it is
available. If you are asked “How many numbers do you need?” and the
TA or the TA/V.34 is the only product you will connect to the line, then
ask for MSN with two DNs. Otherwise, you will need three or more
DNs depending on your installation.

10 TA/V.34 and TA Owner’s Manual
Configuring Your TA/V.34 or TA
Your TA/V.34 or TA must be configured so that it recognizes the DN
or DNs that have been given to you by the phone company.
Configuration means providing information to your TA/V.34 or TA
about the DNs, plus other information. This information will be stored
in a memory device on the board itself.
Configuration Management software is provided to help you do this
configuration and automate much of the process. See the Quick Start
booklet for instructions on installing and running this software. See also
Appendix G: Setting Up ISDN Switches.

Chapter 2 Installation 11
Chapter 2 Installation
This chapter describes installation in computers running Windows 95,
Windows 3.1 or 3.11, or Windows NT 4.0.
Your computer should be located near an ISDN jack.
If you have Windows 95, 3.1, or 3.11, please skip to the top of page 13.
Special Instructions for Windows NT 4.0
While Microsoft has not formally implemented Plug and Play for
Windows NT 4.0, the installation CD-ROM for both the Workstation
and the Server version of the operating system contains a special driver
that will enable Plug and Play. You must install this special driver
before installing your TA/V.34 or TA.
Follow these steps to install the driver:
1. Insert your installation disc into your CD-ROM drive. If
AutoPlay is activated, you will need to click on the Browse
button.
2. Navigate to the following subdirectory: Drivelib\Pnpisa\X86.
3. Find the following file and click on it with your secondary
mouse button (usually the right button): Pnpisa.inf.
4. When the pop-up menu appears, select Install. The Plug and
Play driver will be installed on your hard drive.
5. Remove your installation disc and put it in a safe place. Then
continue with the steps below.
What You Need to Install the TA/V.34 or TA
Make sure that you have received the following items:
•Your TA/V.34 Faxmodem or TA.
•An RJ-45 to RJ-45 phone cord (included) to connect the card to the
ISDN (digital) phone jack.
•Communications software and documentation on CD-ROM or
floppy disks. This software includes some utilities that can help
with installations in non-Plug and Play systems.

12 TA/V.34 and TA Owner’s Manual
•You may also have received an optional standard voice handset
with connecting cord.
To use the TA/V.34 or TA, you also need the following:
•An ISDN line connection (typically, a wall-mounted telephone
jack or socket or an NT1 device). Up to eight S/T devices can be
connected to an NT1 device. You may have other equipment
connected, such as a digital telephone.
•A 486 or faster computer with an available full-size IBM PC-
compatible 16-bit ISA slot, 8 MB RAM, a 3.5” disk drive, a CD-
ROM drive, a hard drive with at least 12 MB available, and
Microsoft Windows 3.1, 3.11, Windows 95, or Windows NT (NT
version 4.0 or higher with a Plug and Play BIOS). A mouse is
recommended.
•A tool, if necessary, for removing and putting back the computer
cover. (See your computer’s manual.)
Installing the TA/V.34 or TA Hardware
1. Turn off and unplug your computer. Do not plug it back in or
turn it on until you finish the installation.
2. Carefully take the cover off your computer. If you need help,
refer to your computer’s manual.
3. Touch a metal surface to discharge static electricity. Static
electricity can damage computer and modem components.
4. Determine whether you must provide termination on your
TA/V.34 or TA. Consult your telephone company or ISDN
installer to determine whether you will need to provide
termination on your ISDN board.
Your TA/V.34 or TA board is shipped without terminating
resistance. However, the board has small connectors, called
jumpers, that can be moved to activate resistance circuitry.
In the great majority of cases, you will not need to change the
jumper settings, and you can skip to step 5 below.
If you determine that your TA/V.34 or TA must provide

Chapter 2 Installation 13
termination resistance, you can set the termination jumpers on
the board as follows:
•Position the board on a firm surface, with the gold
connectors pointing towards you and the phone jack
sockets to your right. Handle the card by the edges,
being careful not to touch the gold connectors;
moisture or oil from your fingers could prevent the
connectors from making a solid connection to your
computer.
•Locate the jumpers. Directly to the left of the larger
jack socket (labeled J9) is a black box (labeled L5).
Directly to the left of the black box are two small black
pieces of plastic with no markings on them. These are
the jumpers. They are on jumper blocks, which are
labeled J3 and J10. See the diagram below.

•Next to each jumper block are numbers indicating the
pins: 1, 2, and 3. The board is shipped with pins 2 and
3 covered by a jumper; to enable the termination
circuitry, you need to move the jumpers to pins 1 and 2
on each block. See the illustration below.
Start with the jumper closest to you. Gently pull the
jumper straight up and move it to pins 1 and 2. Push it
down gently onto the pins. Repeat the procedure with

14 TA/V.34 and TA Owner’s Manual
the other jumper. The board now provides S/T bus
termination of 100 Ohms.

5. Plug your TA/V.34 or TA into an available 16-bit ISA-
compatible slot. (See the illustration below.) If you are
replacing an older modem that is in the slot, now is a good time
to remove it. Look for a board with one or more phone jacks on
it. To remove the modem, unplug any cables connected to it;
then unscrew the screw and lift the board from the slot. If you
are not replacing an existing modem, find an unused 16-bit slot
and remove the slot panel cover next to it. Keep the screw handy
for attaching your new device. Install the TA/V.34 or TA by
pushing it firmly into the slot. Fit the screw into the edge of the
bracket and tighten it.

16-bit slot
6. Replace the cover on the computer.
7. Connect the ISDN line. Your TA/V.34 or TA comes with an
RJ-45 to RJ-45 cable. Plug one end of the cable into the jack on
the card marked ISDN and the other into the ISDN wall jack.
8. Connect the Handset. If a handset was included, plug it into
the RJ-14 jack on the card marked HANDSET. You may use
your own handset or a standard hands-free headset, but not a
telephone. The diagram on page 17 shows how all the
connections should look.
Mounting the Handset
Your TA/V.34 package may contain a telephone handset for use
at your desktop computer. Included for your convenience are a
handset hook and a handset cord retainer.
Use the handset hook to locate the handset in a convenient place
on the side of your monitor. The cord retainer prevents stress on
the handset cord’s connection at the rear of your computer.
To attach the handset hook and cord retainer, peel the
protective paper off the adhesive backs and press them to either
side of your monitor. Be sure to align the the bottom of the hook
horizontally with your desk’s surface so that the handset hangs
straight down. Make sure the monitor is tilted at the angle at
which you usually view it.

10. You are now ready to configure the card using the included
software. Use the following installation instructions for
Windows 95 and Windows NT with Plug and Play BIOS. For
Windows 3.1 or 3.11, see page 20.

18 TA/V.34 and TA Owner’s Manual
Setting Up in Windows 95 and Windows NT 4.0
with Plug and Play BIOS
Note This section is for Windows 95 and Windows NT 4.0. If you
have Windows 3.1 or 3.11, please go to page 20.
If you are running Windows NT, you must be running version
4.0 and a Plug and Play (PnP) BIOS in order to use the
TA/V.34 or TA. To find out whether you have a PnP BIOS
look for a PnP version number during startup, or refer to your
computer documentation. You must also install a special PnP
driver from the installation CD-ROM disc that came with
Windows NT. See the section at the beginning of this chapter
for instructions on installing the driver.
The Plug and Play feature of the Windows 95 operating system
automatically detects your TA/V.34 or TA and allocates hardware
resources with no need for you to set a COM port or IRQ setting. In
Windows NT 4.0, if you have installed the PnP driver and your
computer has a PnP BIOS, Plug and Play will also work.
To complete configuration, follow these steps:
1. Turn your computer on.
2. As the Windows 95 or Windows NT operating system starts up,
a New Hardware Found box is displayed. The first line of this
box should show the name of this product.
3. In the New Hardware Found box, there are three choices for
installing a “driver.” The default is for the driver to be installed
from a disk provided by the hardware manufacturer. Make sure
this choice is highlighted and click OK.
4. An Install From Disk box appears and lists A:\ as the default
drive.
Insert the Utilities diskette in your floppy drive (usually Drive
A). Make sure the correct drive letter is shown in the Install
From Disk box, and click OK.
5. Windows 95 or Windows NT then continues its startup
procedure. Once the system is completely booted up, determine

Chapter 2 Installation 19
what COM port your modem is set to. To do this, open the My
Computer icon on your screen (if it’s not already open). In the
My Computer dialog box, double-click the Control Panel
icon. Inside the Control Panel dialog box, double-click the
Modems icon.
6. In the Modems Properties box, select this product, which
should be listed as a modem found by the system. Then click the
Properties button. Your modem’s properties are listed in a
Properties dialog box. Next to Port is shown a COM number.
Make a note of this COM port number below or in another easy-
to-find place.
COM port: ___________
7. In Windows 95, you can test your TA/V.34 or TA as follows:
While still in the Modems Properties dialog box, test the
modem by clicking on the Diagnostics tab. Choose More Info.
You will see a list of responses. If the entry for ATI 3 contains
the name of your TA/V.34 or TA, your new ISDN card is
properly set up. You may ignore any error messages. Click OK.
(If your modem is not responding, see the section General
Troubleshooting beginning on page 37.)
Close both Properties windows by clicking OK until you get
back to the Control Panel. Skip to step 10.
8. In Windows NT 4.0 Server, if you have previously set up Dial-
Up Networking, a Modem Setup box will appear when you
click OK to exit the Modems Properties dialog box and then
click Close to exit the Modems dialog box. The Modem Setup
dialog box will indicate “Dial-Up Networking needs to be
Click Yes. Dial-Up Networking displays the Remote Access
Service.
In the Remote Access Setup box select TA/V.34 or TA
Internal and click Continue for it to automatically configure
your setup.
Note: If you don’t have Remote Access Service installed, you must
do so to use the Internet or other remote access servers. Refer
to your Windows NT user documentation for installation
instructions.

20 TA/V.34 and TA Owner’s Manual
9. In Windows NT 4.0, you can test your TA/V.34 or TA as
follows:
Start your HyperTerminal application: Click on Start,
Accessories, HyperTerminal, Hypertrm. When the
Connection Description dialog box appears, type in any
name and press Enter. In the Phone Number dialog box,
click on the down arrow next to Connect using. Scroll down
to the Direct to Com xline, where xis the port setting for
your TA/V.34 or TA (see step 6 above). Press Enter. When
the next dialog box appears, press Enter again. You should
now be at HyperTerminal’s main screen.
Type ATI3 (the third character is the letter ‘I’ and not the
numeral ‘1’) and press Enter. If the name of your TA/V.34 or
TA is displayed, your ISDN card is properly set up.
Exit HyperTerminal, answering Yes to terminate the
connection and No when you are asked whether you want to
save the session.
10. Now install and set up your communications software. Follow
the instructions in the Quick Start guide or software user’s
manual that came with the software.
If you need additional help in setting up and configuring your
communications software, see the section Tips for Selecting Setup
Options in the next chapter.
You may also want to review the section about Dial-Up Networking
using ML-PPP or PPP in Windows 95, which begins on page 28.
Setting Up in Windows 3.1 or 3.11
Your computer communicates through devices called ports. These are a
combination of physical connections and logical “addresses” that your
computer assigns to the ports. In addition, your computer uses
“interrupt requests,” or IRQs, to keep port assignments from conflicting
with each other. Once your TA/V.34 or TA has been installed, it must
be assigned to a port.
Under Windows 95, port assignments and IRQs are usually taken care
of automatically by the Plug and Play feature. Under Windows 3.1 and
3.11, you must run a special batch file that will help your computer find
an available port.
