1 Introduction
1 Introduction
1.1 What is ISDN?
ISDN is the internationally standardized digital
telecommunications network. The abbreviation ISDN
stands for Integrated Services Digital Network.
ISDN has three outstanding features that make it diffe-
rent from conventional communications media:
Integration of Services
The first is the integration of services. This means that all
telecommunications services, such as telephony, telefax,
data communications or videotex, are carried over a
single data network. Voice, text, files and even images
can be transmitted over ISDN. Users can connect several
different terminals and use all available services with one
ISDN line. Because the basic-rate ISDN subscriber access
provides two user data channels (B channels), you may
use two different telecommunications services at the
same time—to receive a fax during a telephone
conversation, for example.
High Throughput
The second substantial feature is the extraordinary
speed of data transmission in ISDN. Voice and data are
transmitted over the BRI’s two B channels at the rate of
2 x 64,000 bits per second. Furthermore, the AVM
ISDN-Controller B1 USB allows ISDN applications to
bundle the two B channels so that throughput is doubled.
Outstanding Quality
The third important feature of ISDN is the end-to-end
digital transmission of user data: this is the basis for high
transmission quality. Poor connections, noise and
interference, which cause transmission errors or
interruptions in analog networks, are eliminated. Data
communication over ISDN is thus not only faster, but also
more reliable than in analog networks.
6
1 Introduction
The one terminal device that that exploits the full potential
of ISDN, however, is the personal computer. Before,
separate terminal equipment was necessary for each
service (a fax machine to send faxes, a Vtx terminal for
Videotex, etc.). Today all that is needed is a PC, an ISDN
PC adapter and the desired application software. AVM
has played a major part in bringing about this develop-
ment to combine the power and flexibility of the personal
computer and the ISDN network. With the right ISDN
software, your computer becomes a multimedia
communications center!
1.2 USB: The Universal Serial Bus
The Universal Serial Bus (USB) transports data between
computers and peripherals at a speed of 12 Mbit/s. The
USB brings a new standard in convenience and user-
friendliness to computer hardware: with USB devices,
expanding a computer system is a simple matter of
plugging in a bus cable and installing the driver software.
USB devices all have a uniform connector.
These features make the USB an ideal platform for
connecting input and communications devices to the
computer. The new bus permits true plug-and-play and
”hot” installation, and makes it possible to connect up to
127 peripheral devices.
The USB’s architecture supports all kinds of components.
Guidelines define how different devices are allowed to
use bandwidth on the bus. The USB has a tree-shaped
topology and is regulated by a host controller. Branches
of the tree are connected by hubs; the leaf nodes are the
hardware components to be connected to the computer.
The bus cable can be up to five meters long between two
hubs or between a hub and a terminal device. Hubs can
also be incorporated in the host computer itself, or in
other USB terminal devices, such as monitors or
keyboards.
USB devices are grouped in speed classes. ”Fast devices”
access the bus at 12 Mbit/s throughput, while ”slow
7
1 Introduction
devices” use only 1.2 Mbit/s. (In this classification, the
AVM ISDN-Controller B1 USB is a fast device on the
USB.) Devices can access the bus in several ways,
including bulk, interrupt, isochronous and control modes.
With these characteristics, the USB seems to be an
outstanding solution to the tangle of cables and interfaces
customary in today’s PCs.
1.3 The AVM ISDN-Controller B1 USB
The AVM ISDN-Controller B1 USB is an external
device connecting the computer to an ISDN line.
The ISDN-Controller B1 USB is simply connected to
the USB socket on the computer or any USB hub. Its S
0
interface is then connected to the ISDN line using the
cable supplied.
The AVM ISDN-Controller B1 USB is an active ISDN-
Controller for the S
0
interface of a basic-rate ISDN line,
and is equipped with a high-performance RISC CPU, one
MB of memory and a USB interface. The B1 USB
simultaneously operates both of the BRI’s B channels (for
user data) and the D channel (primarily for signaling
functions).
The B1 USB is a stable platform for professional users
who want support for all ISDN features. The B1 USB can
be connected directly to the ISDN BRI line, or to a PBX
extension.
The AVM ISDN-Controller B1 USB owes its
extraordinary performance to its active architecture,
which makes this ISDN-Controller the ideal platform for
software applications that demand high data throughput.
One megabyte of on-board memory makes it possible to
load protocol processing and other application software
directly on the controller. This minimizes the burden on
your computer’s memory and processor.
The illustration below shows how the ISDN-Controller
B1 USB installation connects the computer to the ISDN
network terminator (NT).

1 Introduction
Fig. 1 Computer with AVM ISDN-Controller B1 USB
The AVM ISDN-Controller B1 USB is completely
software driven. It is equipped with a flash-ROM BIOS that
permits a firmware update by means of a simple software
download. The ISDN software is also downloaded to the
Controller. This concept permits maximum flexibility and
makes it simple to adapt the ISDN-Controller hardware to
new technical developments.
Supported Protocols
The ISDN-Controller’s driver software is loaded from the
host computer’s hard disk. This software handles the
communications protocols and the data transmission.
The Controller software supports the international D
channel protocol DSS1 (”Euro-ISDN”) and the national
protocols 5ESS and NI-1 for the USA, Austel for Australia,
and 1TR6 for Germany.
The driver files for the D channel protocols used in
Germany, DSS1 and 1TR6, are included in the ISDN-
Controller package. The drivers for the other protocols
can be downloaded from the AVM Data Call Center by

direct ISDN connection (+49-30-399 84 300) or over the
Internet (http://www.avm.de; ftp://ftp.avm.de). On the
B channels, the software supports commonly used data
communications protocols including X.75, HDLC trans-
parent, X.31 and transparent connections. For further
technical information, please see Chapter 3, ”Technical
Data”.
CAPI
The driver software for the AVM ISDN-Controller B1
USB provides the industry standard application
programming interface COMMON ISDN API (CAPI) Versi-
on 2.0 (see Chapter 4). This interface, adopted by the
international standardization body ETSI, assures univer-
sal compatibility of ISDN applications and hardware for
ISDN data, fax and voice services.
IDM
The controller software for the AVM ISDN-Controllers
corresponds to the ISDN Driver Model (IDM). For further
informationen about the IDM architecture, please see
chapter 5.
Supported Operating Systems
The AVM ISDN-Controller B1 USB is available for the
Plug & Play operating systems Windows 98, Windows NT
5.0 (in beta test versions at the time of this printing) and
Windows 95 from release OSR 2.0 on with USB extensions
(OSR 2.1). The driver architecture complies with the
Microsoft Win32 Driver Model (WDM).
Several active AVM ISDN-Controllers can be easily
combined in one computer. Up to four active AVM ISDN-
Controllers can be operated at one time.
Installation of the ISDN-Controller hardware and software
completes the connection between the computer and the
ISDN line. The ISDN-Controller package also contains the
communications software suite FRITZ!32 and the AVM
ISDN Tools, a collection of CAPI-based utilities. Other CAPI
applications are available separately: just ask your dealer.

2 Installing the AVM ISDN-Controller B1 USB
This chapter describes how to connect the ISDN-
Controller B1 USB to your computer or USB hub and to
your ISDN line, and how to install the driver software. You
may also read how to load and unload the controller
software, how to handle the ISDN-Controller and how to
change the AVM ISDN-Controller B1 USB’s
configuration settings after installation. The chapter
closes with instructions for removing the ISDN-Controller
B1 USB from the system, and with a description of the
NDIS WAN CAPI Driver.
The AVM ISDN-Controller B1 USB is available for the
operating systems Windows 98, Windows NT 5.0 and
Windows 95 (OSR 2.0) with USB extension.
The installation of the AVM ISDN-Controller B1 USB is
performed in two main phases:
1. The ISDN-Controller B1 USB is connected to
• the power supply,
• the computer or USB hub, and
• the ISDN line.
2. The new hardware component and its driver software
are installed in the operating system.
While the first of these phases is the same for all the
operating systems supported, the second is different, as
the operating systems have different procedures for
setting up a new hardware component and installing driver
software. For details, see the corresponding sections
2.2.1, ”Installation in Windows 98 and Windows NT 5.0”
and 2.2.2, ”Installation in Windows 95 OSR 2.1”.

2.3 Starting the ISDN-Controller; Automatic Loading
If you did not restart Windows at the end of the driver
installation procedure, you may run the program B1
Load in the ”AVM” program group to begin using the
ISDN-Controller B1 USB.
By default, the AVM ISDN-Controller B1 USB is loaded
automatically each time Windows starts up. The ISDN-
Controller is loaded before the Startup program group is
processed, so that you may include CAPI-based ISDN
applications in this group.
The automatic loading mechanism can be deactivated
using the program B1 Setup in the ”AVM” program
group. First unload the ISDN-Controller by running B1
Unload. Then start B1 Setup and change the options in
the dialogs as desired.
Remember to reset your AVM ISDN-Controller B1 USB
by selecting the B1 Load command so that your new
settings take effect.
When you exit Windows, the AVM ISDN-Controller B1
USB is automatically deactivated.
2.4 Plug & Play with the Computer Running

ISDN-Controller B1 USB, or to disconnect it from its
power supply, from the ISDN line or from the USB bus,
without shutting down the computer.
19
2 Installation
Even with this ”hot Plug & Play” capability, however, you
must first terminate any CAPI applications that are active
and unload the ISDN-Controller B1 USB. Then you may
shut off the ISDN-Controller B1 USB or disconnect it
from its power supply, the ISDN line or from the USB bus.
If you switch on or reconnect the ISDN-Controller B1
USB while the computer is running, you must then reload
it by running the program B1 Load in the ”AVM” program
group.
2.5 Automatic Data Compression in Accordance with V.42bis
The ISDN-Controller B1 USB’s driver software is able
to perform data compression in accordance with the
V.42bis standard. Data compression reduces connection
costs by increasing the effective throughput rate,
shortening the necessary connection time.
After installation, the feature CAPI SoftCompression
X75/V42bis is deactivated by default. Applications that
support the V.42bis standard may still negotiate the use
of compression for the duration of a connection with the
remote system, however.
After you have completed the installation of the driver
software, you may activate V.42bis data compression
using the program B1 Setup. When this option is
activated, the driver software attempts to negotiate the
use of data compression in accordance with V.42bis on
every X.75 connection. You should not use this option,
however, if your application already supports V.42bis
data compression. If you have problems establishing
connections, run the program B1 Setup again and
deactivate the data compression option again.
To activate CAPI SoftCompression X75/V42bis,
proceed as follows:
• Start the program B1 Setup in the ”AVM” program
group.
20
2 Installation
• In the D channel protocol selection dialog, click on the
checkbox labeled ”Enable CAPI SoftCompression
X75/42bis”.
• Confirm your option by clicking on Continue, and in
the following dialog click on OK.
• Then restart your computer.
2.6 Removing the ISDN-Controller
To remove the AVM ISDN-Controller B1 USB from your
system, open the Control Panel (under Settings in the
Windows Start menu) and double-click on the Add/
Remove Programs icon. In the list of installed programs,
select the entry AVM ISDN-Controller B1 USB, then
click on the Add/Remove button. The ”Uninstall” pro-
gram starts. All files and entries are then deleted from
your computer. Restart your computer as prompted.
2.7 The AVM NDIS WAN CAPI Driver
