ISDN (Integrated Service Digital Network) is a new,
completely digital, communication network
technology which enables integrated transmission of
voice, images, text and data. ISDN Training System is a
complete study and experimentation program in
ISDN. The purpose of this ISDN training system is the
acquisition of theoretical as well as application
knowledge on the techniques, methods and devices
commonly used in professional ISDN applications
(Central Exchange, Terminal Equipment & protocol
analyzer). The entire set up can be established
without a physical ISDN line.
ISDN Training System consists of:
1. Basic Rate ISDN exchange with Protocol Analyzer.
2. ISDN Telephone sets.
3. ISDN Terminal Adaptors.
4. Analog Telephone sets.

B-Link4 simulates the operation of a central office
switch which provides three Basic Rate ISDN
connection (S 4-wire ), which may be used like a
regular ISDN line.
B-Link4 is extremely easy to use with indicator LED’s
showing at a glance what each terminal is doing and
a windows application program displaying protocol
analyzer information and allowing extensive device
configuration. Almost every feature of B-Link4 can be
customized, for e.g. the entire directory numbering
structure can be changed. Special numbers activate
network conditions such as User Busy or Call Rejected
The protocol analyzer for the B-Link4 can be used to
decode all messages being transmitted or received
by the B-Link4 through BRI. It can Analyze Layer 2 (Data
Link Layer) and Layer 3 (Call Control Layer)
ISDN Telephones and Terminal Adaptors are provided
along with the system, which can be used as the
equipment on the subscribers end. Using the Terminal
Equipment students can understand the use and
features of ISDN in the laboratory.
FEATURES:
• No physical ISDN Line required.
• 3 BRI Ports with S Interface.
• Simulates all the functionality of regular ISDN lines.
• Built in Protocol Analyzer facility.
• Helpful LEDs to show the status of each interface at a glance.
• Emulates Euro-ISDN type of network variants.
• Simple configuration using windows application.
