"Intelligent Networks were devised in an effort to... 1. enable the uniform implementation of services." 2. provide the capability for networks to automatically calculate telephone bills." 3. enable the uniform interconnection of several network architectures." Answer Question 2 Which of the following statements is true? "In an Intelligent Network, new services can be created by... 1. using a service matrix construction table." 2. restructuring services form other networks around the world." 3. combining service independent building blocks." Answer Question 3 Which of the following statements is true?
    • "An Intelligent Network improves the standard of services provided to customers because... 1. services are devised in a more 'intelligent' way." 2. many companies compete to provide the best services." 3. it enables customers to subscribe to more than one service." Answer Question 4 Which of the following organisations have been involved in the international standardisation of intelligent networks (INs)? 1. The International Telecommunications Union (ITU). 2. The Intelligent Network International Standards Organisation (INISO). 3. The European Telecommunications Standardisation Institute (ETSI). 4. Bellcore and the Multi-Vendor Interaction Forum (MVIF). Answer Question 5 Which of the following statements is true? "In the context of Intelligent Networks, the INCM is... 1. the Intelligent Networks Communications Manager." 2. the Intelligent Node Connection Model." 3. the Intelligent Network Conceptual Model." Answer Question 6 Which one of the following diagrams, shows the correct ordering of the planes in the INCM:
    • 1. 2.
    • 3. 4. Answer Question 7 Which of the following statements is true? "In the context of the Capability Set 1 service plane, POIs are... 1. Points Of Intelligence, where software takes over the control of the networks switching."
    • 2. Process Organisation Instructions, specifying how the system should organise the current requests for services." 3. Points Of Initiation, where the basic call handling process is branched away from to handle service requests. " Answer Question 8 Which of the following diagrams is a true representation of the call handling process in the CS-1 service plane? 1. 2. 3.
    • Answer Question 9 Which of the following statements is correct? "The initial objective of the TINA consortium (TINA-C) was to... 1. develop an international club for dedicated Tina Turner fans." 2. define a software based architecture which would enable the efficient introduction of telecommunications services." 3. set up an organisation for researching and developing possible architectures for future networks." 4. develop an information networking architecture that could be used on any type of network, for both telecommunications and operations applications." Answer Question 10 Which of the following statements is correct? "The TINA-C... 1. aims to promote the use of TINA world-wide." 2. was derived from a general concern that changes in the modern world would require a wider strategic vision with respect to network architectures, than the traditional vision." 3. aimed to considerably increase the range of current mobile cellular phones." 4. developed hardware allowing communication services, as well as multi-media applications to be run on the same hardware platform." Answer Answers to Questions Answer to Question 1
    • 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. Next question 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.
    • Next question 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. Next question 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
    • 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. Next question Answer to Question 7 Answer : 3) "In the context of the Capability Set 1 service plane, POIs are Points Of Initiation, where the basic call handling process is branched away from to handle service requests." Next question
    • 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. Next question 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
    • 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.
