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.
