REGULATORY COMPLIANCE
FCC Part 15 Class A Notice: This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.

ISDN Demonstrator
INTRODUCTION
ISDN (Integrated Systems Digital Network) is a system which combines
telephone and computer networking in a digital medium. The ISDN BRI
(Basic Rate Interface) is the interface for individual users to connect to the
public telephone network. An ISDN BRI is composed of three separate
channels of information called 2B+D, that is, two full duplex Bearer channels
and one full duplex Delta channel combined onto a single pair of wire.
The Teltone ISDN Demonstrator is two ISDN BRI connections in a portable
housing. The user interface is “U” connection using an RJ45 modular plug.
The “U” connection is similar to the interface that is provided by a local
telephone service provider (LEC), such as one of the Bell Operating
Companies, or an independent telephone company. Using this connection,
the user is able to place calls, either voice or data, or both, using the National
ISDN-1 signaling standard. AT&T 5ESS Custom provisioning is available as
a separate option (ILSATT-01).
ISDN is based upon an OSI (Open System Interconnection) model. The
ISDN Demonstrator supports layer 1 (physical operation), layer 2 (data link
operation), and Layer 3 (network operation.) Layers 4-7 are considered
application layers that use the first 3 layers as a base.
The ISDN Demonstrator has been developed to make demonstrating of
ISDN CPE equipment easier. Integrators, and sales representatives now
have an ISDN-BRI server in a box. The ISDN Demonstrator supports ISDN-
BRI end-to-end operation, multiple Call Control protocols, telephony switch
services, and simple functional operation on the desktop or lab bench.

CHAPTER 1: QUICK START
The ISDN Demonstrator is easier to operate than most communications
devices designed for ISDN-BRI applications. It functions in the background,
providing two lines of end-to-end ISDN-BRI service.
Because the Simulator was designed primarily for people who demonstrate,
functionally test, or configure ISDN-BRI devices, you do not need to
understand ISDN protocols or read the entire User’s Manual to use it. Simply
follow the instructions outlined below to successfully demonstrate most
ISDN-BRI communications devices and computer applications.
Step 1 Place the Simulator on a flat surface near the ISDN equipment
to be connected.
Step 2 Insert the power cord into the three-pronged outlet located at
the rear of the Simulator. Plug the other end into a standard
115 VAC, 60 Hz wall outlet.
Step 3 Apply power to the Simulator by pressing the power switch -
located at the rear of the Simulator - to the PWR ON position.
An internal self-test, lasting about 30 seconds, is performed.
The STATUS LED located on the front panel will switch
between Red and Green during this self-test. The STATUS
LED changes to a continuous solid green if the self-test is
completed satisfactorily.
Step 4 The Simulator is configured at the factory for National ISDN-1
protocol. The Simulator is provisioned for default service, as
normally practiced for the selected switch type. Most
communications devices operate correctly with this
provisioning. However, if your communications device does
not operate correctly, you may need to change the Simulator’s
provisioning. These settings are fully described in Chapter 3. A
list of recommended settings for different terminal types (AT&T
CUSTOM) is available in the ISDN Demonstrator configuration
software.
NOTE: The instructions for many ISDN-BRI
communications devices may specify Switch Provisioning
required of the telephone company. Provisioning is a
means of configuring the ISDN switch so it knows what
kind and how many calls your communications devices
can handle, up to the limits imposed by ISDN-BRI
technology. Provisioning also specifies which types of
Supplementary Services your equipment may request,
such as call appearances, display support, etc.
Step 5 A 3.5" diskette is provided with the ISDN Demonstrator to
change the configuration of the ISDN Demonstrator. To install
this windows based software, place the diskette in the
