Chapter 1:
Introduction
The Trust Communicator ISDN 128 Internal is designed for
Windows 95. It is fully Plug & Play, so the installation is very
fast and easy.
The Trust Communicator ISDN 128 Internal board connects
your computer to the ISDN Basic Rate Interface, giving you
access to the fastest public communications network for the
integrated transfer of voice, data, still and video images.
The CAPI driver allows you to use your existing
communication programs with the Trust Communicator ISDN
128 Internal.
The following system requirements must be met:
•AT personal computer
•Pentium processor
•8 MB of RAM (recommended 16 MB)
•Windows 95 operating system
•A free 16-bit ISA slot
•10 MB hard disk space
Note
The Trust Communicator ISDN 128 Internal has been designed for use with
Windows 95. It does not work with Windows 3.11, DOS, Windows NT and
OS/2.
The package contains programs for the various ISDN
services. There are 3 disks and 1 CD-ROM included in the
package. They have the following function:
•Driver disk 1 and 2. These are the device drivers for the
card. They are required for all ISDN use.
•The ‘Microsoft ISDN Accelerator Pack’ (IAP) disk. This is
the driver to access the Internet at 128 kbps.
•The application software CD-ROM. This CD-ROM includes
a program to send fax documents to G4 (ISDN) and G3
(analog) fax-machines and terminal programs for ISDN

4
services. This CD-ROM is not needed to access the
Internet.
Note
If you use your ISDN adapter only to access the Internet and not for other ISDN
services, a faster installation is available by first installing the IAP (chapter 5.4.1,
part 1 & 2) and then following the instructions in chapter 3 and 4.

Chapter 2:
About ISDN lines and services
Currently, ISDN services can differ greatly in protocols and
procedures across countries. Your Trust Communicator ISDN
128 Internal has been designed to support most ISDN
switches and protocols. Contact your local phone company to
obtain the Basic Rate Interface best suited to meet your
individual needs. Before installing the software, you should be
aware of the services and protocols provided. This is
essential for setting the right parameters for each ISDN
application.
The D channel protocol for your Basic Rate Interface is
determined by your local phone company. When installing
your software you will be requested to enter the type of D
channel protocol your BRI is configured to.
The Trust Communicator ISDN 128 Internal supports the
most common D channel protocols and ISDN switch types:
European protocols International protocols US ISDN switch types
ETSI (EURO-ISDN) INS64 (Japan) AT&T Custom
1TR6 (Germany) NI-1
VN-3 (France) Northern Telecom
DMS-100 (Custom)
CT-1 (Belgium)
MSN (Multiple Subscriber Numbers)
The DSS1 protocol identifies terminal equipment by MSN.
MSNs provide a set of several call numbers that can be
assigned to different ISDN services. This allows you to use
several ISDN applications or devices on a single ISDN line.
