3. Basics of ISDN

3.1 What is ISDN ?

ISDN is an abbreviation for Integrated Services Digital Network, a modern
communications network. ISDN lets you enjoy all the many facets of electronic
communications. You can surf the Internet, balance your accounts using home
banking services, or remotely connect to your company's computer network.

3.2 What Does ISDN Have to Offer?

The ISDN telecommunications network offers subscribers digital payload channels
(B channels) with a maximum transfer speed of 64 kbps. The most important
improvement of ISDN over conventional analog public communications networks is
that ISDN supports a variety of different types of telecommunications services.
ISDN connections are not limited to data, as is the case with some other network
types, but are equally suitable for carrying speech, text, or images.

This constitutes a tremendous economic advantage, since the same lines can be
used for speech, fax, or data communications as needed. Standard ISDN access to
Euro features 2 B channels and 1 D channel (for service and control purposes).
ISDN is unrivaled when it comes to dial-up connections:

Connections are established quickly (in approx. 1.8 seconds)
No handshaking process, unlike standard analog modems
Optimized use of resources
High transfer rate of 64 kbps per B channel

3. Basics of ISDN

In addition to the B payload channels ISDN features a parallel service channel
called D channel. This channel is used to carry information on establishing and
terminating connections as well as data relevant to in-call control.

The subscriber line that the ISDN user is provided with is called basic access. Each
basic access offers two B channels with a bandwidth of 64 kbps each and a D
channel with a bandwidth 16 kbps.

B channels can either be used separately or combined for greater data transmission
bandwidth. The present ISDN terminal adapter thus offers its users flexible
bandwidth , provided that this channel combination feature (trunking) is supported
by the software used.

3. Basics of ISDN

3.3 ISDN Access

Converting a standard analog phone line to ISDN has become very simple these
days. The existing phone line can simply be changed over to ISDN at a specified
point in time. Since ISDN uses existing telephone cables, the telephone company
does not need to run any new lines to your house or office.

At the end of the phone line you need an NTBA (network terminator/bus adapter) to
convert the two-wire signals for the four-wire ISDN S0 bus.

3.4 Features

ISDN offers a great variety of features, especially for voice communications. The
basic functions, however – establishing and terminating connections – are usually
quite sufficient for data communications. Consult your ISDN service provider for
available features.

3.5 PABX or Multiple Device Access?

Depending on how you wish to use ISDN, there are two types of ISDN basic access

PABX access
Multiple device access

3.6 Access Type: PABX

PABX access always requires a PABX to be connected. All subsequent terminal
devices are connected to the PABX as extensions. PABX can also handle analog
terminal devices. You will receive a block of subscriber numbers with several direct
extension numbers, allowing individual terminal devices to be addressed (dialed)
directly.

To connect an ISDN terminal adapter to ISDN via PABX access, you need a PABX
with an internal S0 bus.

3.7 Access Type: Multiple Device

Up to 8 terminal devices can be connected to the S0 bus of each multiple device
access. Two of them can establish a connection at the same time, each using one B
channel.

You will be assigned several Multiple Subscriber Numbers (MSNs) for your multiple
device access. By assigning different MSNs to different devices on the S0 bus, you
can address these directly.

10

4. Drivers and Applications

4.1 Overview

You can use your ISDN Adapter for a wide variety of applications. The most
important applications are:

Online services - Internet access via PPP (direct dial-up to an Internet
provider), AOL, CompuServe, and others.

Direct data interchange between two PCs.

Telecommunications services - e.g. fax (analog/G3 or digital/G4),
voicemail, Euro File Transfer.

BBS access using terminal emulator programs.

Since, historically, these applications evolved independently of each other, different
types of driver concepts are required for ISDN integration. NDIS WAN Miniport,
CAPI, and VCOMM are the most important of these drivers and are of course
supported by your ISDN Adapter. Each driver offers at least two basic functions:

Opening and closing a connection (D channel)
Transferring payload data (B channel).

4. Drivers and Applications

4.2 NDIS WAN Miniport

The NDIS WAN Miniport driver was specified by Microsoft and is a part of Windows
95/98 and Windows NT. The connection is controlled by the RAS (Remote Access
Service, Dial-Up Network). Special drivers, namely Microsoft’s NDIS WAN Miniport
and ISDN Accelerator Pack constitute the connection to the ISDN Adapter. When
the RAS has established the connection, the ISDN Adapter is seen by Windows as
a network interface card similar to those used for local area networks (LANs). This
means that all programs that can exchange data over a LAN can use this pathway
for communicating via ISDN.

11

4. Drivers and Applications

The NDIS WAN Miniport driver is therefore optimally suited for the following
applications:

Internet access - The Dial-Up Network establishes an ISDN connection
with your Internet provider. The Web browser (Netscape, Internet
Explorer) or the E-mail client subsequently use this connection like a
TCP/IP LAN connection to the Internet.

Direct connection of two PCs - The Dial-Up Network establishes a
connection to a second PC via ISDN. Windows Explorer then creates a
Windows network connection between the PCs using the NetBEUI
protocol. Once this is done, each PC can access the other PC’s hard disk
just like a disk on a LAN server; data can be copied or moved, and
applications can be run.

Connection between a remote PC and a LAN - The Dial-Up Network
establishes a connection to a router or server connected to a LAN, e.g. a
company server. Subsequently, Windows Explorer establishes a Windows
network connection using the NetBEUI, TCP/IP, or IPX protocol. Once this
is done, each PC can access the other PC’s hard disk via ISDN as if it
were connected directly to the LAN. In this manner, it is possible to
duplicate your in-company working environment at your home office.
Thanks to the high speed of the ISDN connection, remote access is
convenient and fast.

The Siemens ISDN Adapter in conjunction with the NDIS WAN Miniport driver is
integrated into Windows as a network interface card during installation. To this end,
the system environment consisting of the ISDN Accelerator Pack, Dial-Up Network,
and LAN protocol (NetBEUI, TCP/IP, IPX) is examined and completed as needed.
Subsequently, the requisite internal connections to these components are
established.

4.3 CAPI

12

The NDIS WAN Miniport hardware driver is also used by the other ISDN interfaces
(CAPI, VCOMM). It is entered as a network adapter in the Windows registry.

The CAPI (Common Application Program Interface) was defined to be able to
develop ISDN applications independently of the proprietary characteristics of ISDN
adapters. One of the most remarkable CAPI features is platform independence. In
addition to Windows, the CAPI has been defined for Unix, OS/2, and other
operating systems. The older CAPI Version 1.1 should no longer be used; the
current CAPI version is 2.0.

4. Drivers and Applications

Some standard CAPI applications are:

Online services
Online services should be configured to use the CAPI wherever possible,
as this offers you the fastest and safest service access.

Fax (analog and digital)
ISDN application program suites usually use the CAPI for all services,
including analog (Group 3) and digital (Group 4) fax. Analog faxing
requires a softfax module, which is a component of the ISDN driver. This
driver should be used instead of any softfax module offered by the
application, since it uses the PC’s resources more economically.

Euro File Transfer
Euro File Transfer (EFT) was developed for the simple exchange of files
via ISDN. It replaces the X/Y/Zmodem protocols. You can call any EFT
server the way you call a BBS and upload or download files.

Voicemail
CAPI programs are able to preserve B channel data without any
modification. These data may include digital speech from a telephone call.
It is immaterial whether the call originates from within the analog phone
network or from an ISDN line. Voicemail programs play back
announcements to callers and record messages.

The CAPI interface is able to handle ISDN Adapter with different properties. If you
wish to use a specific application, you need to make sure that the ISDN Adapter
meets the application’s requirements. Some applications may need special B
channel protocols, hardware phone connections, or similar.

The technical specifications for your ISDN Adapter are found in the Appendix.

Only one CAPI can be installed at any time, because the
CAPI2032.DLL file must be located in a specific directory and each
directory can only contain one file by the same name. This means
that if you previously installed a CAPI device on your PC, you will
have to deinstall it first before you can install the CAPI of the new
ISDN adapter. If you fail to do so, the old files will be overwritten,
which may result in system crashes and misconfigurations in certain
cases.

Make sure to remove all previous CAPI installations before
installing this device.

8. I-Surf USB Utilities

8.1 ISDN Configuration Wizard

The ISDN Configuration Wizard lets you change the basic ISDN settings entered
during software installation:

ISDN D channel protocol
The ISDN D channel protocol does not usually have to be changed. It

is supplied by your telephone company and has to be configured
accordingly. For a European ISDN access this will almost always be
DSS1 (Euro ISDN). If you do not know which D channel protocol you
are using, please contact your telephone company.

MSNs for the two B channels
Each MSN is one of your ISDN multiple subscriber numbers that can

be used to call you on ISDN. These numbers are assigned by the
telephone company and can be configured separately for each ISDN
B channel.

Note that these MSN settings are used only for the loopback test
program and for the Dial-Up Network.

Under Windows 98 changes on these settings take only effect if you
restart your computer.

The program establishes a connection "with itself", sending data and receiving
them. The data received are compared to the data sent.

This program is found in I-Surf ISDN Utilties program folder. It can be started by
clicking the Loopback Test icon.

8.3.1 Prerequisites of the Test

The following conditions must be met for the loopback test to be run:

The ISDN Adapter must be installed.
The ISDN (S0 bus) cable must be connected.
The second B channel of the S0 bus must be free, that is, no other

connection may be active on the same ISDN line. Any analog device
connected to the ISDN Adapter (phone, fax, modem) must be on­hook.

8.3.2 Testing Criteria and Testing Procedure

8. I-Surf USB Utilities

The loopback test will test the following components:

ISDN access wiring
D channel protocol setting
Hardware component function
NDIS WAN Miniport driver installation
CAPI2032.DLL installation

39

8. I-Surf USB Utilities

The loopback test follows this pattern:

1. The ISDN Adapter is addressed (initialized).

2. An ISDN data connection is established to the multi-subscriber

8. I-Surf USB Utilities

4. Watch the messages in the status window showing the current status
of the test connection and the test result. Status messages are given
in text form and as CAPI or ISDN error numbers.

5. If the test was successful, the following message appears:

If the loopback test was passed, you can assume that your ISDN Adapter hardware
and software are operating properly.

If the loopback test was not passed, this could be due to one or more of the
following errors:

Error in ISDN access wiring (inverted wires)
Incorrect plug connections
Loose connections within jacks
Terminal resistor pack missing
Incorrect D channel protocol settings
Incompatible ISDN provider D channel protocol
Incorrectly configured MSN
MSN incorrectly configured by the ISDN provider

9.6 Other Applications

There is a wealth of other applications you can use with your ISDN Adapter. Please
consult the respective documentation for information about installing and using this
software.

For the application to interact properly with the ISDN Adapter, note the following:
Make sure the version of the application you are using supports the driver versions

offered by your ISDN Adapter (NDIS WAN Miniport, CAPI...). You can determine
this by the application software installation routine or by the existence of files with

names like ISDN... or CAPI.... When in doubt, contact the software vendor for

information about the type of driver required.

44

10. Internet access

10.1 Microsoft Dial-Up Network

When the driver software has been successfully installed, you can use the Dial-Up
Network to connect your computer to other computers or networks.

To do so, you will first need to have your server or provider provide you with the
access parameters for the dial-up connection. The following example will show you
how to establish a connection with a server using the Microsoft Dial-Up Network (or
the Microsoft Remote Access Service, RAS).

Depending on your user privileges, you will be able to access the resources on the
server (hard disk, printer, etc.). You can also use this connection to transfer data
from one PC to another (PC-PC connection, file transfer).

Have the following information handy before setting up the Dial-Up Network
connection:

- Access number des Servers/Providers

- User name on the server

- Password for this user name

- Information on the protocols and IP addresses used

10. Internet access

1.

When you have received your ISDN access number, user name, and password,
create a new connection for the Windows Dial-Up Network.

Make a new connection using My Computer | Dial-Up Network. Select one of the
modems ISDN Line 0 or ISDN Line 1, and give the new connection a name of your
choice (here: MyGroup).

45

10. Internet access

2. Enter the server’s area code and subscriber number (here: 01111)

This concludes the definition of the connection. You will now have to select the
correct network protocols.

46

3.

To activate the required network protocols for this newly created connection, you
will have to change the server type. Right-click the new connection icon, and
select Properties.

10. Internet access

4. Select the appropriate settings for the protocols supported by the server (here:
TCP/IP):

Limiting the number of protocol will speed up the connection process. Now you
can connect to the server by double-clicking on the connection icon.

47

10. Internet access

5. Enter your user name and password.

If your server access is valid and your user data were correctly entered, you
should now be connected to the server via the network.

10.2 Regular ISP With Multilink PPP

If you want to use a multilink connection (i.e. a connection with which you can
transfer data via both B channels at a total of 128 kbps) through the Dial-Up
Network, proceed as follows after creating the connection:

1. Select My Computer | Dial-Up Network.

48

Right-click the new connection icon, and select Properties.

10. Internet access

2. Click Settings under Set additional devices, then click Add to add a device.

49

10. Internet access

For example, if the connection uses ("Using:") ISDN Line 0, you may add ISDN
Line 1 to Set additional devices to activate the multilink function for this

connection. This will make 128 kbps bandwidth available to you.

50

You may add another connection by clicking Add. You need to enter the channel
not yet used for this connection.

Any multilink connection, however, requires that your dial-up server supports this
feature and that your account has the necessary access privileges. Multilink
connections, for instance, do not work for CompuServe.

10.3 Online Services

You can use your ISDN Adapter to access a variety of online services. Online
services offer a broad spectrum of information services that is continuously being
updated. Online services offer up-to-date information, the way newspapers and
magazines have done, but by an electronic route. Learn all you can about what the
different services have to offer before signing up with the service most suitable for
your needs.

Major online services usually offer their own software packages you can use to
access thse services.

The software packages of most major online services include CAPI support. You
may therefore select the CAPI as access mode instead of a modem when installing
this type of software.

The major online services also offer Internet access as part of their software, so you
can use the Internet as well if the respective gateway is activated for you.

More detailed installation instructions are found within the respective software
packages.

11. Troubleshooting

11.1 Hardware Installation

The PC cannot be booted.

Check to see if all cables were connected properly.

11.2 Device Driver Installation/Operating System

“Fax operation not possible.”

Fax operation is only possible with software using the CAPI interface. Check
software installation if needed.

“Dial-up connection not possible.”

Check to see if the device is connected to the S0 bus. It will usually be necessary to
activate the Ignore dial tone setting of the software used if the device is connected
to a PBX. If a connection still cannot be established, check the PABX hookup, and if
necessary contact our support hotline.

“No calls can be accepted.”

Check the settings of your software to see whether it is set to automatic or manual
answer. Furthermore, ensure that the correct MSN has been assigned to the
device.

“Internet connection cannot be established.”

Check to see if the TCP/IP is activated in the Network applet of the Control Panel.
Check the Dial-Up Network Windows online help topic to see which other protocols
must be activated.

“Device not recognized.”

Start the PC with only indispensable boards installed, plus the ISDN Adapter. If the
device still is not recognized, please exchange or check for system compatibility
with the ISDN Adapter.

53

11. Troubleshooting

11.3 Dial-Up Network

If you wish to use the ISDN Adapter with the Windows Dial-Up Network, you will first
have to configure a connection. Once a connection is configured, click the
connection icon to establish the connection. The current connection status will be
displayed in the status window. Error messages indicating possible causes of the
error will be displayed in case a connection cannot be established.

Connection broken before “Verifying user name and password” is shown

If the connection is broken before the message "Verifying user name and password"
appears, no ISDN connection could be established with the server. Use the
loopback test to check whether the ISDN Adapter and ISDN access work properly.
Also, check that you are using the correct access number for your server. If using a
PABX, it may be necessary to dial "0" or "9" before the number. Try calling a
different server (test server) known to be fully functional.

Connection broken after “Verifying user name and password” is shown

If the connection is broken before the message "Verifying user name and password"
appears, an ISDN connection was established with the server. If problems occur
after this point, they may be related to the network configuration or the server
configuration. Contact the server's PC or LAN administrator.

11.4 CAPI Applications

If you experience problems with CAPI applications, you should first perform the
loopback test. If the test was passed, all CAPI applications should operate properly.
However, the following exceptions might apply to your case:

54

The CAPI application may use a B channel protocol not supported by
the ISDN Adapter. A list of supported protocols is found in the
Appendix.

The CAPI application may use the CAPI.VxD or CAPI.SYS kernel
mode drivers instead of the CAPI3220.DLL user mode driver. The
kernel mode drivers are not tested by the loopback test. Contact your
application manufacturer’s customer support.
