Introduction
1.1 An Overview of the ISDN USB TA
1.1.1 What is ISDN?
ISDN is an abbreviation for Integrated Services Digital Network.
ISDN transfers information digitally and integrates all
telecommunication services (such as telephone, teletext, videotex,
etc.) into a single network. Using ISDN, you can transfer text, voice,
data files, images, and even video.
Before the use of ISDN, telecommunications operated using analog
devices, which limited the quality of telecommunication transfers.
With ISDN technology, the telephone lines can transmit data
digitally with much greater speed and clarity of transmission than
with analog transmissions. The ISDN is capable of transmitting all
kinds of information at greatly accelerated rates. A typical modem
transmission has a rate of 33.6Kbps (kilobits per second or thousand
bits per second). ISDN digital technology allows transfer rates of up
to 128Kbps.
Because ISDN transmits data digitally, the data is virtually error
free, and the transmission is much clearer, with fewer interruptions

and slowdowns in facsimile transmissions. With ISDN devices
implemented throughout the world, a truly digital network will
emerge, allowing everyone fast and easy access to the global
information highway.
1.1.2 What is USB?
USB is an abbreviation for Universal Serial Bus. It is a new
peripheral bus employing a single connector type for all low-speed
and medium-speed devices, such as keyboard, mouse, monitor,
floppy drive, printer, scanner, digital camera, modem and ISDN TA.
It brings plug-and-play of computer peripherals outside the box,
eliminating the need to install cards into dedicated computer slots
and reconfigure the system. PCs equipped with USB allow computer
peripherals to be automatically configured as soon as they are hot
attached, without the need to reboot. USB also allows multiple
devices, up to 127, to run simultaneously on a computer. Some
peripherals, such as monitors and keyboards, can act as additional
plug-in hubs to make it easy for users to manage peripherals on the
desktop. USB does offer unprecedented peripheral expandability and
ease of use for PC users.
With better throughput of 12Mbps (megabits per second or million
bits per second), USB is expected rapidly to become the preferred
means of connecting ISDN TAs, though it will not replace the
traditional PC ports (COM and LPT) overnight.
1.1.3 The ISDN USB TA
The ISDN USB TA is ideally suited to give your PC access to the
world of the Integrated Services Digital Network. It is easy to install,
and easy to configure because it is fully plug-and-play compatible.
The Windows 98 or 2000 operating system automatically installs
and configures the ISDN USB TA.

Chapter 1 — Introduction

With the ISDN USB TA, you can have an answering machine, file
transfer, videotex, G3/G4 Fax functions, and Internet access. This
brings you more versatility and efficiency in the ISDN era.

1.3 ISDN USB TA Features
The ISDN USB TA supports many standard and enhanced features,
including the following:
♦It is fully plug-and-play compatible.
♦It hot-attaches and detaches without rebooting the PC.
♦It is bus-powered, with no extra power adapter.
♦It provides telephony functions with a headset (optional).
♦It supports both 16-bit and 32-bit CAPI drivers.
♦It supports TAPI and NDIS WAN miniport drivers.
♦It supports Multilink PPP (MP) for 128Kbps (two B channels)
Internet access and data transfer.
♦It supports X.75, T.70NL, ISO8208, T.90, and HDLC
transparent protocols on the B channel for T-Online, AOL,
CompuServe, BTX, BBS, Eurofile transfer, and G4 Fax.

Chapter 1 — Introduction

♦It has support for a bit-transparent driver on the B channel for
answering machine, G3 Fax and soft-modem functions.
♦It supports both V.110 and V.120 rate adaptation.
♦It supports COM port simulation for modem-based application
programs.
If you want to send and receive the Group 3
(G3) fax at 14.4Kbps, you should have a
Pentium processor.

Installation
2.1 Before Installing
Make sure that you have all you need to install the ISDN USB TA.
You should have the following:
1. A PC that has a USB connector and a USB controller that is
working properly as shown below:
FIGURE 2-1: CHECKING THE USB CONTROLLER IN THE PC

Chapter 2 — Installation
7
2. Microsoft Windows 98 or 2000.
For some PCs without a USB connector, you
may have to connect an adapter to your
motherboard so that you can plug in your USB
peripherals.
As a quick rule of thumb, if your PC was made
during or before 1996, it probably doesn't
support USB. If it was made during 1997, it
probably supports USB. If it was made during or
after 1998, it almost certainly supports USB.
3. At least 10MB of free disk space for the driver and
software.
4. An ISDN basic rate ST interface released by PTT (Post,
Telephone and Telegraph administration).

2.2 The Front Panel LEDs
LED Meaning
USB When this LED is lit, it indicates that the USB port is
connected to the PC and working properly.
ISDN When lit, it indicates that the ISDN S0 bus is activated. It
flashes when there is message transfer in the D channel.
B1 When lit, it indicates that the ISDN “B1” channel is being
accessed. It flashes when there is data transfer in the B1.
B2 When lit, it indicates that the ISDN “B2” channel is being
accessed. It flashes when there is data transfer in the B2.
PC When this LED is lit, it indicates that there is at least one
application program using the ISDN USB TA.

2.3 Installing the ISDN USB TA
Please refer to the following instructions and figures for installation
procedures:
FIGURE 2-2: CONNECTING THE ISDN USB TA
1. If there is a switch on the back of the ISDN USB TA, turn it
off.
2. Connect your ISDN line to the RJ-45 jack labeled “ISDN
S0” on the back of the ISDN TA.
3. If the ISDN TA has optional “MIC/SPK” jacks, you can
connect a headset.

4. Connect the USB cable to the jack labeled “USB” on the
back of the ISDN TA. Connect the other end to the PC or to
a self-powered USB hub device, e.g., monitor.
You should not connect the ISDN USB TA to a
bus-powered USB hub device, such as keyboard,
because there could be not enough power for the
ISDN TA.
5. If there is a switch, turn on the ISDN USB TA.
6. All the LEDs will be lit and, then, extinguished one by one.
Please refer to Chapter 3, Troubleshooting, if any LED is
not lit or extinguished as described here.
