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.

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.

CD ROM drive and harddisk

If you are using a different operating system or your PC does not meet one of the
above requirements, please contact your dealer.

5.2 USB Hardware Interface

The USB (Universal Serial Bus) interface is a modern computer interface allowing
you to connect up to 127 different peripheral devices (such as printers, cameras,
speakers) to your computer.

5. USB Installation

The devices can be connected or disconnected while the system is up and running
(hot-pluggable devices). Low-power USB devices do not need their own power
supply.

Your ISDN Adapter is a low-power USB device requiring its own USB Port. If all the
USB ports of your computer are already in use, you need to use a USB hub to
increase the number of available USB ports.
