CHAPTER: 1 1.1 Introduction A telephone directory (also called a telephone book and phone book) is a listing of telephone subscribers in a geographical area or su subs bscr crib ibers ers to serv servic ices es provi provide ded d by the the orga organiz nizat atio ion n that that publishes the directory. It consists of the name as well as the telephone number of people added as contact in the directory. Name and telephone number are displayed in alphabetical order.

1.2 Content Subscriber names are generally listed in alphabetical order, together with their













Zealand. Pract Zealand. Practic ices es as to the the disp displa lay y of Caller-ID on call callss made made by unli unlist sted ed subscribers vary by jurisdiction. Sometimes the Caller-ID on outbound calls is not shown; in other jurisdictions unlisted numbers are displayed unless the caller dials a blocking code; in others the customer may request automatic blocking by the telephone company. In the US, under current rules and practices, mobile phone and Voice over IP listings are not included in telephone directories. Efforts to create cellul cellular ar direc director tories ies have have met stiff stiff opposi oppositio tion n from from severa severall fronts fronts,, includ including ing a significant percentage of subscribers who seek to avoid telemarketers telemarketers.In .In 1991 the U.S. Supreme Court ruled (in Feist v. Rural ) that telephone companies do not have a copyright on telephone listings, because copyright protects creativity and not the mere labor of collecting existing information. Within the geographical reach of the Court, the Feist ruling has resulted in the availability of many innovative telephone directory services on CD-ROM and the World Wide Web. Web .

1.3 Objectives We are are dete determ rmin ined ed to desi design gn a sy syst stem em whic which h is in inte tend nded ed in saving name and number of desired persons. The main objective of telephone directory is to add, search, edit and delete various contacts.

1.4 Applications Telephone directory has been frequently in use in our daily life. Wecommonly see telephone directory installed in PSTN telephone sets, mobile phone etc. Telephone Directory application provides the ability to search, view, and manage entries in a directory. Mobile Directory application should allow any subscriber with any type type of mobi mobile le devi device ce that that su supp ppor orts ts GPRS GPRS to ins insta tant ntly ly searc search h















CALL, SAVE, VIEW, SEND TO FRND or DISCARD. Mobile Directory eliminates the need to call any other call center.

individual can be stored in the external memory (EEPROM). As further these records can be further manipulated by retrieving them from the EEPROM. These contacts can be edited, deleted, also searched as required by the user . There are mainly two parts in the block diagram. a. Software part b. Hardware part

Software part ;Software enables us to perform specific tasks. Software is a tool that interfaces with hardware and implements the user specifications. For interfacing between microcontroller and LCD, microcontroller and Keypad and EEPROM various software tools are used. The software tools used are as follows:













a. Microcontroller b.LCD display c. EEPROM d.Keypad













Apache tomcat 6.0

3.2 Basic Components :It is important to get acquainted with the integral components and its purpose that is used in this project before going through the project details. The list of the major components that are used are as follows: Hex Keypad :- Keypads are a part of Human Machine Interface and play really important role in a small embedded system where

• Delay in pressing the keys cannot be achieved perfectly. • EDIT option in this project could not be implemented. • Memory management is a great drawback. • This unit is having problem when back button is pressed. Problem Occurred During Programming













Further Implementati Implementation:on:- This architecture architecture is a basic basic backbone backbone for other electronics projects. • The concept of “Telephone Directory “can be implemented with interfacing of MMC cards using SPI (Serial Peripheral Interface). • This architecture can be used in systems such as 1.Password Based door lock 2.Restaurant Automation System This architecture can be implemented in all systems that uses













Technical feasibility centers on the existing manual system of the test management process and to what extent it can support the system. According to feasibility analysis procedure the technical feasibility of the system is analyzed and the technical require requiremen ments ts such such as softwa software re facili facilitie ties, s, proced procedure ure,, inputs inputs are identified. It is also one of the important phases of the system development activities. The system offers greater levels of user friendliness combined with greater processing speed. Therefore, the cost of maintenance can be reduced. Since,processing speed is very high and the work is reduced in the maintenance point of view view manag managem ement ent convi convinc nce e that that the the proj projec ectt is opera operati tiona onall lly y

Software cost estimation is the process of predicting the effort required to deve lop a software system. Many estimation models have been proposed over the last 30 years. This paper provides a general overview of software cost estimation methods including the recent advances in the













subsystem level. The total project level has the ad vantage that all cost components of the system will be considered while the subsystem level has the advantage of providing a more detailed assessment of the similarities and differences between the new project and the completed projects. The strength of this method is that the estimate is based on actual project experience. However, it is not clear to what extend the previous project is actually representative of the
