CE Approval

All CE approved ISDN devices may be connected to the Euro­ISDN in all countries of the EU.

USB ISDN TA has been approved by the German TÜV
according to the new European procedure and may therefore be
connected to the Euro-ISDN in all EU countries. This ISDN TA
therefore complies with:

♦ CTR-3 (ISDN Basic Rate Access)
♦ Electromagnetic Compatibility Standards
♦ Safety Standards

CE/EMC Restriction of Liability

The product described in this handbook was design ed, produced
and approved according to the EMC-regulations and is certified
to be within EMC limitations.

If the product is used in an uncertified PC, the manufacturer

Introduction

1.1 An Overview of the USB ISDN 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
56Kbps (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 low­speed 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 to rapidly 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 USB ISDN TA

The USB ISDN 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-p lay
compatible. The Windows 98, Me, 2000 or XP operating
systems will automatically install and configure the USB ISDN
TA.

Installation

2.1 Before Installing

Make sure that you have all you need to install the USB ISDN
TA. You should have the following:

1. A PC that has USB connector and its USB controller is

working properly as shown below.

2. Microsoft Windows 98, Me, 2000 or XP.

3. At least 30MB of free disk space for the driver and

software.

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 this LED is lit, it indicates that the ISDN S

0

bus is activated. It will flash when there is message
transfer in the D channel.

B1

When this LED is lit, it indicates that the ISDN B1
channel is being accessed. It will flash when there
is data transfer in the B1.

B2

When this LED is lit, it indicates that the ISDN B2
channel is being accessed. It will flash 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 USB ISDN TA.

2.3 Connecting the USB ISDN TA

Please refer to the following instructions and figure for installing
the USB ISDN TA:

1. Connect the ISDN S

0

line to the RJ-45 jack.

2. Connect the USB cable to the USB port and connect the

other end of USB cable to the PC. Refer to the
following figure.

Chapter 2 Installation

7

You should not connect the USB ISDN TA to a
bus-powered USB hub device, such as keyboard,
because there could be not enough power for the
ISDN TA.

3. 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 normally.
