Answers to Questions
Answer to Question 1

7. Answer : 1)
"Intelligent Networks were devised in an effort to enable uniform implementation of
services."
This is because IN's separate the services from the physical network and centralise
them in an intelligent node. This enables new services to be created, provided and
implemented in the same way.

Answer to Question 2
Answer : 3)
"In an Intelligent Network new services can be created by combining service
independent building blocks (SIBs)."
The service designer combines specific SIBs into SIB chains, in order to create new IN
services.
Next question
Answer to Question 3
Answer : 2)
"An Intelligent Network improves the standard of services provided to customers
because many companies compete to provide the best services."
In the traditional system, a single company would be responsible for running the
physical network and all the services available on that network. However, in the IN
environment, service provision becomes an open market, making it possible for many
different companies to offer users services of their own. This makes the market
competitive and hence forces companies to innovate to gain market share, thus
improving the standards of services offered to the public.

Answer to Question 4
Answer : 1), 3) & 4)
In 1989, the international standardisation of INs was instigated by the International
Telecommunications Union (ITU) and the European Telecommunications
Standardisation Institute (ETSI). Both bodies aimed to develop recommendations for a
series of compatible IN capability sets (CSs). However, IN have been studied by other
organisations throughout the world, aside from ITU and ETSI. The other big player in
the context of IN standardisation is Bellcore, US, with its advanced intelligent network
(AIN) program. AIN documents do not represent real international standards but are
considered to be standards in North America.

Answer to Question 5
Answer : 3)
"In the context of Intelligent Networks, the INCM is the Intelligent Network Conceptual
Model."
This specific modelling tool defines IN architectures based on the IN service capabilities
to be supported.
Next question
Answer to Question 6

9. Answer : 2)
The INCM was developed to capture the whole engineering process of the IN. The
model has four specific planes, as shown above. The lower two planes focus on the IN
architecture, whereas the upper two planes focus on service creation and
implementation.

the basic call handling process is branched away from to handle service requests."

10. Answer to Question 8
Answer : 3)
This diagram shows the true representation of the call handling process in the CS-1
service plane. The Basic Call Process (BCP) begins to deal with a call. If services are
required, the BCP branches to the service logic which executes the required Service
Independent Building Blocks (SIBs) and on completion, branches back to the BCP.

Answer to Question 9
Answer : 2), 3) & 4)
Work currently being undertaken on telecommunications information networking
architectures (TINAs) may well provide the architectural principles for future networks.
In 1993, the Telecommunications Information Networking Architecture Consortium
(TINA-C) was founded, the objectives being to define an architecture into which
telecommunications services could be introduced quickly and efficiently. It was intended
that the service functionality should be implemented in software, running on a widely
dispersed hardware platform.
Next question

11. Answer to Question 10
Answer : 1) & 2)
The Telecommunications Information Network Architecture Consortium (TINA-C) was
founded because of a concern that traditional network architectures are limited, and that
future network demands will need a wider strategic vision. A software based
architecture is being developed, which adopts state of the art concepts, such as IN,
TMN and ODP. It is hoped that TINA implementations will be carried out world-wide,
once a complete TINA specification has been finalised and some of the current
architectural problems have been overcome.
