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.

6TA/V.34 and TA Owner’s Manual
We occasionally insert spaces between commands to make a command
line easier to read. You can type the command line with or without
spaces between commands as long as the command line does not
exceed 255 characters (spaces count as characters).
•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
NT support for version 4.0 or higher.
•Flash memory for code updates via software downloads.

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.
