1 Introduction

1.1 What is ISDN?

ISDN is the internationally standardized digital telecom-

munications network. The abbreviation ISDN stands for

Integrated Services Digital Network.

ISDN has three important new features that distinguish it

from conventional communications media:

The first is the integration of services. This means that

all public telecommunications services, such as tele-

phony, data communications, telefax, Teletex or video-

tex, 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 ISDN

subscriber access (called a basic-rate interface, or BRI)

provides two user data channels (B channels), two differ-

ent telecommunications services may be used at the

same time—to receive a fax during a telephone conver-

sation, for example.

The second significant difference is the extraordinary

speed of data transmission in ISDN. Voice and data are

transmitted over both of the BRI’s B channels at the rate

of 2 x 64000 bits per second. Furthermore, the AVM

ISDN-Controller A1 PCMCIA allows ISDN applications

to bundle the two B channels so that throughput is

doubled.

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 inter-

ference, which can cause transmission errors or interrup-

tions in analog networks, are eliminated. Data commu-

nication over ISDN thus is not only faster, but also more

reliable than in analog networks.

Yet it was the personal computer that opened up the full

potential of ISDN: it used to be that each service required

different terminal equipment (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 role in

bringing about this revolutionary development to com-

bine the power and flexibility of the personal computer

and the ISDN network. ISDN and the appropriate commu-

nications software make the PC truly multifunctional!

1.2 The AVM ISDN-Controller A1

The AVM ISDN-Controller A1 creates the connection

between your PC and the ISDN network.

Figure 1 PC with AVM ISDN-Controller A1

As the illustration shows, the ISDN-Controller is simply

plugged into a free ISA/EISA bus slot in the PC. A cable

supplied with the ISDN-Controller connects the ISDN-

Controller’s S

interface to the ISDN line.

The AVM ISDN-Controller A1 handles both B channels

of an ISDN BRI line (2 x 64000 bit/s) simultaneously.

Thanks to its compact dimensions, the A1 is quite

suitable for small computer housings. The AVM ISDN-

Controller A1 is a passive adapter: that is, the card has

no microprocessor of its own. All computing is per-

formed by the PC’s processor.

1 Introduction

CAPI

Supported protocols The driver software for the AVM ISDN-Controller A1 is

loaded from the PC’s hard disk and controls the signaling

processes and data transmission, including the simulta-

neous use of both B channels. The software supports the

international D-channel protocol DSS1 (Euro-ISDN) as

well as national protocols like 1TR6. In Microsoft Win-

dows, the protocols 5ESS and NI1 also are supported.

Protocols supported on the B channels include the

common data communications protocols X.75, HDLC

transparent and others.

The AVM ISDN-Controller A1’s driver software pro-

vides the industry standard application interface

COMMON-ISDN-API (CAPI) Version 2.0 (see the Appen-

dix). In Windows 98, Windows 95, Windows NT and

Windows 3.x, this CAPI version also supports applica-

tions based on CAPI 1.1.

This manual describes installation of the AVM ISDN-

Controller A1 hardware and software. This installation

establishes the connection between the computer and

ISDN. Also included in delivery of the Controller are AVM

ISDN-Tools, a collection of CAPI-based applications.

Contact your distributor to purchase any additional CAPI

applications.

1.3 Package Contents

2 Hardware Installation

2.1 Instructions for Various Operating

Systems

The AVM ISDN-Controller A1 can be operated on a

variety of software platforms. The exact installation

procedure for the ISDN-Controller varies according to the

operating system in question.

If you work with Windows NT, Windows 3.x or MS-DOS,

first check which I/O address is available in your PC and

change the jumper position on the Controller if necessary

(see Section 2.2). Then install the Controller and the

driver software.

A different sequence of steps is valid for installation in

Windows 95/98. See the instructions for these operat-

ing systems in Chapter 3, “Driver Software Installation”.

2.2 Adjusting the I/O Address

In order to manage and use the ISDN-Controller, the

system must communicate with it through an I/O (input/

output) address.

The default values set on the AVM ISDN-Controller A1 are

an I/O address of 300 and an interrupt (IRQ) level of 5.

If the I/O address is already being used by another

adapter, change the setting before installing the Control-

ler. The ISDN-Controller has one jumper row; the position

of the jumper determines the I/O address. The I/O

address corresponding to each jumper position is listed

in Chapter 4, “Technical Specifications”, and also is

marked beside the jumper contacts on the ISDN-Control-

ler itself. The interrupt can be changed using the A1

Setup program after completion of the software installa-

tion.

To install the Controller it may be necessary to change

the I/O address from the factory setting of 300, for

instance, if other hardware components use this ad-

dress.

The I/O address is changed by moving a jumper on the

ISDN-Controller card, then entering the new address in

the ISDN-Controller driver software or operating system

configuration. This section describes the hardware

adjustment: moving the jumper. The procedure for

adjusting the software configuration is described for

each operating system in Chapter 3, “Driver Software

Installation”.

The ISDN-Controller has one jumper row containing one

jumper. To locate the jumper row, hold the board in front

of you with the component side up. The controller

Troubleshooting – General Malfunctions

5 Possible Errors and Remedies

This chapter describes general malfunctions and specific

error messages and suggests how these may be resolved.

Error messages are sorted by operating platform:

Windows 98, Windows 95, Windows NT, Windows 3.x

and MS-DOS.

5.1 General Malfunctions

The AVM ISDN-Controller is not detected or not initialized.

• Have you installed other new hardware components

or changed the configuration of existing hardware?

If so, check for conflicts in the interrupt and I/O

address assignments using the program MSD.EXE,

which is included with MS-DOS and Microsoft Windows

3.x. In Windows 95/98, look for resource conflicts in

the Device Manager (“Start / Settings / Control Panel/

System“). In Windows NT, run the program “Windows

NT Diagnostics” in the “Administrative Tools” folder.

• If your computer is a PCI/ISA bus system, check your

BIOS setup or ICU utility to make sure that the

interrupt you assigned to the AVM ISDN-Controller

A1 is actually allocated to the corresponding bus.

• Have you made changes in your computer’s BIOS

setup?

• Have you made other configuration changes (boot

menus, memory managers, etc.)?

You are unable to establish an ISDN connection.

If the AVM ISDN-Controller is correctly installed, but you

are unable to establish a connection, check the following:

• Is the ISDN-Controller firmly inserted in the bus slot?

Is its slot plate screwed down?

Troubleshooting – General Malfunctions

• Are the ISDN cable connectors firmly inserted (and

screwed tightly) in the AVM ISDN-Controller? Is the

connector cable connected to in your ISDN socket?

• Is your ISDN line active? Use another terminal device,

such as an ISDN telephone, to check it.

• Is your network terminator (NT) installed correctly?

Some NTs need to be connected to an electrical

outlet as well as to the incoming ISDN line.

• If your ISDN-Controller is connected to a PBX exten-

sion, have you included the outside dialing prefix

(usually ‘0’) in the numbers dialed?

• Are all the relevant services (data transmission)

available and enabled on your PBX extension?

• Did you specify the correct D-channel protocol for

your ISDN line when installing the ISDN-Controller

software?

Problems during ISDN-Controller operation:

If problems arise regularly during operation, run the

program A1 Test, located in the “AVM” program group

or in the driver software installation directory. This

program performs functional tests of the ISDN-Controller’s

individual components and displays the results.

If A1 Test reports no malfunctions in the ISDN-Controller

hardware, you should attempt a test connection to the

AVM Data Call Center (ISDN file transfer server). You may

do so using the program Connect2 (MS-DOS) or

Connect32 (Windows 95/98 and NT), which are among

the AVM ISDN-Tools included with your ISDN-Controller.

The number of the AVM Data Call Center is +49-30-399

84 300.

Troubleshooting – General Malfunctions

After you have run the diagnostic program “A1 Test“, the

CAPI interface is no longer available

Reload the AVM ISDN-Controller A1: in Windows,

restart the systems; in MS-DOS, enter the command

ibase.

Connections to analog dial-in ports.

Your AVM ISDN-Controller can establish connections to

digital ISDN terminal equipment. In addition to this, you

may send and receive faxes (Fax Group 3 = analog fax)

in Windows. The drivers for Windows 95, 98 and Windows

NT also allow connections to analog ports like modems.

For this purpose, you can use FRITZ!com or other

applications together with the AVM ISDN CAPI Port Driver.

See the CAPI Port Driver’s help file. In the Appendix, you

find more information about the driver software’s features

CAPI SoftFax G3 and CAPI SoftModem V32bis.

DOS and Windows drivers are loaded at the same time

Load either only the DOS drivers or only the Windows

drivers for your AVM ISDN-Controller. Windows drivers

also support CAPI applications in DOS windows.

No line charge information is displayed

The drivers for the AVM-ISDN Controller A1 allow CAPI-

based applications to display charge information. This

information is available only if the corresponding ISDN

service has been enabled by your ISDN service provider,

however. Contact your ISDN service provider to request

charge information.

5 Troubleshooting – Error Messages

5.2 Error Messages

5.2.1 Error Messages in Windows 98

In Windows 98 no error messages are returned directly.

Thus error conditions are not visible until an application

has been opened. Possible error messages include

“CAPI not installed” and “Error 680: no dial tone”, a

message from Windows Dial-Up Networking.

Possible solution: Check the Controller configuration in

the Windows 98 Device Manager. The Device Manager

is opened via “Start / Settings / Control Panel / System”.

The entry “AVM ISDN-Controller” displays all ISDN-

Controllers installed. Double-click on an ISDN-Controller

entry to view the properties of the device. The page lists

all resources currently assigned in the system including

I/O addresses and interrupts. Any resource conflicts in

the system also will be displayed. Should any conflicts

exist, change the Controller configuration accordingly

here. See also Chapter 3 for allocating resources.

5.2.2 Error Messages in Windows 95

Error message: “No AVM ISDN-Controller with the confi-

gured I/O address found.”

Possible error source: The I/O address set with the

jumper on the Controller is different from the entry in the

Windows Control Panel (Device Manager), or the hardware

is not installed.

Solution: The I/O address set with the jumper must

match the entry in the Device Manager. Open the Device

Manager (“Start / Settings / Control Panel / System”) and

select the AVM ISDN-Controller A1. Click Properties

and then on the “Resources” page. Use the Change

Setting button to enter the I/O address corresponding to

the jumper position on the Controller. Restart Windows

for the changes to take effect.

5 Troubleshooting – Error Messages

If the Device Manager indicates a device conflict for the

desired I/O address, select another one. After shutting

down the computer, move the jumper on the Controller

to this address and then restart the computer.

Error message: “The configured interrupt cannot be used”.

Possible error source: The AVM ISDN-Controller A1

and another hardware component (e.g. a sound card) are

set to the same IRQ value.

Solution: Open the Device Manager (“Start / Settings /

Control Panel / System”) and select the AVM ISDN-

Controller A1. Click Properties and then on the

“Resources” page. Select “Interrupt Request” as the

resource type. Use the Change Setting button to set

the value to a free IRQ. Windows 95 automatically

displays any potential conflicts with other installed

hardware. To implement changes made here, Windows

95 must be restarted.

Error message: “A required .DLL file, CAPI*.DLL, was not

found.”

Possible error source: The DLL file (CAPI.DLL,

CAPI20.DLL or CAPI2032.DLL) has been renamed or

removed from the Windows\System directory.

Solution: Perform a complete new installation of the

AVM ISDN-Controller A1 to replace the missing files.

Error message: “Windows has finished detecting hard-

ware, but did not find any new devices on your system.”

Possible error source: The Add New Hardware Wizard’s

question “Do you want Windows to search for your new

hardware?” was answered with “Yes” during AVM ISDN-

Controller A1 installation.

Solution: Start the Add New Hardware Wizard again and

answer this question with “No”. Confirm by clicking

Next. See “Installation in Windows 95/98” in Chapter 3,

“Driver Software Installation”.

5 Troubleshooting – Error Messages

5.2.3 Error Messages in Windows NT

Error message from Windows NT: “At least one service or

driver failed during system startup. Use Event Viewer to

examine the event log for details.”

Possible error source: The AVM ISDN-Controller A1

driver software cannot be loaded. This may be due to an

incorrect I/O address setting (jumper setting on the

Controller) or to an incorrect interrupt (IRQ).

Solution: For detailed information about the error, open

the Windows NT Event Viewer (“Administrative Tools”

folder). Check the messages from A1BASE and the

Service Control Manager.

The “Administrative Tools” folder also includes the

“Windows NT Diagnostics” program, with which you can

check the resources in your system. Find out which I/O

addresses and interrupts (IRQs) are available.

If the jumper position on the Controller must be changed

to another I/O address, exit Windows and turn off the

computer. Change the jumper position, restart Windows

NT, and then start the A1 Setup program from the “AVM”

group to enter the new I/O address and any change to the

interrupt (IRQ).

As a final step, Windows must be restarted to implement

these changes.

Error message: “Resource conflict detected...“

Possible error source: The ISDN-Controller cannot use

the configured I/O address or interrupt (IRQ), as it is

already assigned to another device.

Solution: Change the IRQ or the I/O address. Use the

“Windows NT Diagnostics” program from the “Admini-

strative Tools” folder to find out which I/O addresses and

interrupts are available. Turn off your computer, change

the jumper position and then restart Windows. Use the

A1 Setup program to make the corresponding changes

to the software. See sections 4.1 and 3.2.2 for more

information.

5 Troubleshooting – Error Messages

Error message: The interrupt does not work.

Possible error source: The interrupt (IRQ) may be

assigned to another hardware component which was not

installed with a driver correctly in NT.

Solution: Set the AVM Controller A1 to another IRQ.

Turn off the computer, change the jumper position on the

Controller and then restart Windows. Start the A1 Setup

program and follow the instructions on the screen. See

also section 4.1.

Error message: The ISDN-Controller has not been found,

has not been activated by the system or does not work

properly.

Solution: Perform the Controller installation again. Work

through the steps in the sequence listed in the installation

routine in section 3.2. If problems persist, contact AVM

Support. See section 5.3 for contact information and

useful instructions.

5.2.4 Error Messages in Windows 3.x

Error message: “No AVM ISDN-Controller with the config-

ured I/O address found.”

Possible error source: The jumper position on the

Controller which determines the I/O address does not

correspond to the settings in the A1 Setup program, the

I/O address is used by another hardware component

(e.g. sound card), or the hardware is not installed.

Solution: Find out which I/O addresses are available in

your PC and set the jumper position on the Controller

accordingly (see Chapter 4,“Technical Specifications”).

Then enter the new I/O address in the driver software

using the A1 Setup program from the “AVM” program

group. Windows must be restarted for the changes to be

implemented.

5 Troubleshooting – Error Messages

Error message: “The configured interrupt cannot be used”.

Possible error source: The AVM ISDN-Controller A1

and another hardware component (e.g. a sound card) are

set to the same IRQ value.

Solution: Check which interrupts (IRQs) are available in

your computer using the MSD.EXE program (Windows

directory). Then start the A1 Setup program from the

“AVM” program group and define another interrupt for the

Controller. Windows must be restarted for these changes

to take effect.

Error message: “Missing or wrong entry in SYSTEM.INI:

invalid I/O address”.

Possible error source: The I/O address entry in the

SYSTEM.INI file is incorrect or missing.

5.2.5 Error Messages in MS-DOS

Error message: „ISDNLOAD: installation error, controller-

xx with I/O address <xxx> not found.“

Possible error source: The jumper position on the

Controller which determines the I/O address does not

correspond with the entry in the A1 Setup program, the

I/O address is used by another hardware component

(e.g. a sound card) or the hardware does not exist.

Solution: Check which I/O addresses are available in

your computer and set the jumper on the Controller

accordingly (see Chapter 4 “Technical Specifications”).

Then enter the new I/O address in the driver software

using the A1 Setup program. After making these

changes, load the Controller using the ibase.bat file.

Error message: “ISDNLOAD: installation error, interrupt

<xx> not available”.

Possible error source: The AVM ISDN-Controller A1

and another hardware component (e.g. a sound card) are

configured to the same interrupt.

Solution: Check which interrupts (IRQs) are available in

your computer using the MSD.EXE program (DOS

directory). Start the A1 Setup program and set another

interrupt. Then load the Controller using ibase.bat.

Appendix: The Applications Interface

CAPI 2.0

Introduction

COMMON ISDN API (CAPI) is a standardized software

interface that provides applications with access to ISDN

adapters on basic-rate and primary-rate lines. Applica-

tions that build on this standard interface use uniform

mechanisms for communication over ISDN connections,

and thus do not need to adapt to the peculiarities of

particular manufacturers’ hardware. This means that

such applications are also unaffected by future exten-

sions or hardware modifications: CAPI makes such

changes transparent to the application. ISDN hardware

manufacturers benefit from this standard too, since it

makes all kinds of applications compatible with their

products.

CAPI contains an abstract definition of ISDN services

which is independent of the specifics of underlying

telecommunications networks or the adapter cards used

to connect PCs to ISDN. The specification provides an

interface that is easy for application programmers to

use, and thus offers uniform access to various ISDN

services such as data, voice and fax transmission, video

conferencing and telephony.

CAPI has evolved into an internationally recognized stan-

dard. Key in this development have been the numerous

advantages offered by this uniform interface: indepen-

dence from specific manufacturers and consequent high

investment security, a wide variety of compatible applica-

tions for all kinds of operating systems and ISDN proto-

cols, etc. ISDN (the Integrated Services Digital Network)

is becoming attractive for an increasing number of

companies since it affords fast and reliable transfer of

information in many different forms.

What is CAPI?

Benefits of CAPI

Appendix The Applications Interface CAPI 2.0

As early as 1989, ISDN manufacturers began develop-

ment work on a standard interface for the rapidly expand-

ing ISDN market. The first version of CAPI concentrated

on the German national ISDN protocol 1TR6, as an

international standard for ISDN protocols was not yet

available. In 1990 development was complete, and a

CAPI Working Group was formed by ISDN application and

hardware manufacturers, large-scale ISDN users, user

groups and the German PTT, at that time DBP Telekom.

CAPI Version 1.1 was a milestone in the development of

the national ISDN market in Germany. Today all German

ISDN solutions and a large proportion of international

products are based on CAPI.

The international standardization of ISDN-protocol speci-

fications is now complete, and nearly all telecommunica-

tions network operators provide BRI and PRI lines on the

basis of the international standard Q.931/ETS 300 102.

With CAPI 2.0 a version based on this standard now is

available.The experience gained in Germany and other

countries over the past years in the development of an

ISDN applications programming interface, along with the

enormous base of installed CAPI solutions, have contrib-

uted greatly to the development of this new applications

interface for international ISDN systems.

Over ten years of experience in the growing ISDN market

have gone into CAPI 2.0. This version has all the

advantages of an open interface and covers most ISDN

features (including data communications, telephony,

Group 3 fax and video conferencing). Since CAPI handles

ISDN subscriber interface control functions, these no

longer have to be programmed. This simplifies the

development of ISDN applications. Furthermore, appli-

cations no longer have to be tailored to national or

manufacturer-specific systems, so that a greater variety

of applications is available.

By using CAPI Version 2.0, the international market

benefits from comprehensive technological know-how

with great profit potential.

or several ISDN adapters

• Support for multiple concurrent applications

• Message definitions independent of operating sys-

tems

• A message-passing mechanism tailored to specific

operating systems for optimum system integration

• An asynchronous, event-driven mechanism for high

throughput

IDM Architecture

The ISDN Driver Model (IDM) illustrated below integrates

ISDN into the Microsoft family of operating systems.

Figure 10 IDM architecture

The ISDN Driver Model provides the framework for all

driver components of AVM ISDN products. The IDM

describes the integration of all ISDN services and their

utilization by the application. The IDM also fixes the

transparent integration of ISDN hardware resources in

the operating system.

An important element of IDM is the bonding of existing

communications components like RAS to CAPI-based

ISDN solutions. This is achieved using Middleware like

the AVM CAPI Port Driver or the NDIS WAN CAPI Driver.

The IDM architecture allows the parallel use of CAPI,

modem and network application functions in ISDN. A

particularly important feature is the option of defining and

activating additional functions, for example integrated

data compression according to V.42bis and Fax G3

service.

Appendix The Applications Interface CAPI 2.0

CAPI SoftCompression X.75/V.42bis

CAPI SoftCompression is a feature of the Controller A1

driver software. Data compression for X.75 connections

according to V.42bis significantly reduces connection

times and costs by increasing transmission rates.

Applications which support the V.42bis standard can

negotiate data compression with the remote site for the

duration of data transmission. In this case, data com-

pression is activated or deactivated at the request of your

ISDN application, e.g. by Connect32. When the driver

software is installed, CAPI SoftCompression X.75/V.42bis

is deactivated by default.

When using older ISDN applications which do not support

data compression, you have the option of switching on

data compression directly in the AVM ISDN Controller

A1 driver. Thus data compression is enabled for all ISDN

connections.

When data compression is activated in the driver, the

program will attempt to negotiate data compression

according to V.42bis for all X.75 connections, indepen-

dent of the CAPI application in use. If the remote partner

does not perform data compression, data will be trans-

mitted without compression. This procedure runs in the

background and is invisibIe to the user.

Once the driver software has been installed, V.42bis data

compression can be activated in Windows 98/95 and

Windows NT using the A1 Setup program. In Windows 3.x

you have the option of activating data compression during

the installation routine.

If your laptop or notebook does not meet the hardware

requirements or if unexpected problems arise when

exchanging data with remote sites without V.42bis capa-

bility, it is advisable to deactivate data compression in

both the driver and the application.

If problems in establishing connections arise, deactivate

data compression.

Appendix The Applications Interface CAPI 2.0

CAPI SoftFax G3 and CAPI SoftModem V32bis

Along with CAPI SoftCompression, CAPI SoftFax and

CAPI SoftModem are also features of the Controller

software. In addition to digital features, the Controller

A1 also allows the use of analog services like Fax Group

3 (CAPI SoftFax G3) and modem (CAPI SoftModem

V32bis).

The AVM ISDN-Controller A1 can be used with the

Controller software as a platform for CAPI-based fax

applications in Windows. The Controllers support send

and receive procedures for faxes with up to 14400 baud,

with both B channels available for fax communication.

The Controller functions as a Group 3 fax machine.

The AVM ISDN-Controller A1 also offers SoftModem

V.32bis. On the basis of this modem emulation, commu-

nications applications can use an ISDN line to establish

connections to analog remote partners connected to the

telephone network by modem. The modem emulation

enables data transmission according to V.32bis. This

means that data connections can be operated at up to

14400 baud.
