ISDN Line Simulator
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 Data channel combined onto a single pair of wires.
The Teltone ILS-2000 (ISDN Line Simulator) is two ISDN BRI connections in
a portable unit. The user interface is either a “U” or an “S/T” 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. The “S/T”
connection uses a built in NT-1 (Network Termination 1) to connect to
Terminal Equipment that includes TE1s, TAs, and TE2s. Using these
connections, the user is able to place calls, either voice or data, or both,
using the National ISDN-1, AT&T 5ESS, Custom DMS100, or ETSI.
ISDN is based upon an OSI (Open System Interconnection) model. The ILS-
2000 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 ILS-2000 ISDN Line Simulator has been developed to make the
transition from traditional telephony to ISDN networking easier. Software
developers, manufacturers, integrators, and sales representatives now have
an ISDN-BRI
server in a box
. The ILS-2000 supports ISDN-BRI end-to-end
operation, multiple Call Control protocols, telephony switch services, and
simple functional operation on the desktop or lab bench.
