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 different from conventional communications media: Integration of Services The first is the integration of services.
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 development to combine the power and flexibility of the personal computer and the ISDN network.
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.
1 Introduction Network terminator NT S0 interface AVM ISDNController B1 USB Controller software USB 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.

On the B channels, the software supports commonly used data communications protocols including X.75, HDLC transparent, 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) Version 2.
1 Introduction 1.4 Package Contents The AVM ISDN-Controller B1 USB package contains: • the AVM ISDN-Controller B1 USB (the external ISDN-Controller for the USB) • 6-meter ISDN cable to connect the ISDN-Controller to the ISDN line • one 3.5” floppy disk with the Setup program for the operating systems Windows 98 and Windows NT 5.0 • one 3.5” floppy disk with the Setup program for the operating system Windows 95 OSR 2.0 with USB extension (OSR 2.1) • one 3.
2 Installation 2 Installing the AVM ISDN-Controller B1 USB This chapter describes how to connect the ISDNController 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.
2 Installation Specially developed driver software is supplied for use with the ISDN-Controller B11 USB. This 32 bit device driver provides full support for all features of Microsoft Windows. AVM is continually revising and improving its driver software and provides updates free of charge. The latest drivers for the AVM ISDN-Controller B1 USB can be downloaded from the AVM Data Call Center using the file transfer program FRITZ!data (included).
2 Installation • Examine the USB cable. It has a different connector at each end, one plug with a flat, rectangular crosssection (called the Series A plug) and one with a square cross-section (the Series B plug). • Connect the Series A plug to the USB socket of your computer or USB hub. • Then connect the Series B plug to the socket labeled ”USB” on the ISDN-Controller B1 USB. • After you have connected the ISDN-Controller B1 USB to your computer or hub, the second LED from left also lights up.
2 Installation • Insert the floppy disk labeled ”AVM ISDN-Controller B1 USB, Installation Windows 98/NT 5.0” in your 3.5" floppy disk drive. If the driver software was supplied on a CD-ROM, insert the B1 USB CD in your CD-ROM drive. • In the next dialog you are asked, ”What do you want to do?” Select the option ”Search for the best driver for your device.” Then click on Next. • In the next dialog the Wizard asks where to search for the driver software.
2 Installation • Next, enter the folder in which you want the driver software for the ISDN-Controller B1 USB installed on your computer. The default is C:\IDRIVER. You may confirm this or enter any other path. When you have entered the path to the desired folder, click on Continue. • In the next dialog, select the D channel protocol used on your ISDN line (DSS1 or 1TR6). Click on Continue to confirm your choice. • The Setup program now copies all the necessary files to the specified folder.
2 Installation 2.2.2 Installation in Windows 95 OSR 2.1 After you have connected the ISDN-Controller B1 USB to your computer or USB hub, Windows 95’s Plug & Play mechanism detects the ISDN-Controller. The Windows driver database is updated, and the Add New Hardware Wizard displays a message box with the title ”New Hardware Found” and the message ”The Hardware Wizard is installing the following device: Unknown”. Click on OK.
2 Installation • To finish the hardware component installation, the computer must be restarted. Answer Yes at the corresponding prompt. If you installed the driver from a floppy disk, remove it from the floppy drive now. • After Windows has started again, the sign-on window of the AVM ISDN-Controller B1 USB Setup program appears automatically. Click on Continue. • In the next dialog, select the option ”Installation” and then click on Continue.
2 Installation The B1 Setup program allows you to adjust the settings for the D channel protocol, automatic loading of the ISDNController B1 USB and data compression, without reinstalling the driver software. The document B1 Readme contains the latest information on the ISDN-Controller B1 USB. Use the program B1 Test to test your ISDNController B1 USB for correct installation and working order. 2.
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.
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.

4 The Application Programming Interface COMMON ISDN API 2.0 4 The Application Programming Interface COMMON ISDN API 2.0 4.1 General Information What is CAPI? Common ISDN API (CAPI) is a standardized software interface that allows ISDN applications to operate ISDN adapters connected to BRIs and PRIs. Applications that build on this interface use uniform methods and do not have to be adapted to the particular characteristics of various manufacturers’ hardware.
4 The Application Programming Interface COMMON ISDN API 2.0 CAPI 1.1 As early as 1989, ISDN manufacturers began developing a standard interface for the rapidly growing ISDN market. The first version of CAPI was oriented toward the German national ISDN protocol 1TR6, since there was not yet an international standard for ISDN protocols.
4 The Application Programming Interface COMMON ISDN API 2.0 Common ISDN API Version 2.0 presents the international market with a comprehensive technology and the potential for high benefits. Further information about COMMON ISDN API 2.0 you will find in the Internet under the following address: http://www.capi.org 4.
5 The ISDN Driver Model Architecture 5 The ISDN Driver Model Architecture The ISDN Driver Model (IDM) shown below illustrates the integration of ISDN into the operating system familiy of Microsoft. Fig. 2 IDM architecture The ISDN Driver Model forms the framework for all driver components of the AVM ISDN products. The IDM describes the integration of ISDN into the operating system environment and the application interface, in order to use all performance features.
