The digital Electronic Private Automatic Branch Exchange system (EP ABX) is the future of telecommunications. It is used in offices, industries, hostels, hotels, universities and in commercial complexes- networking or in transmission. It is a system capable of handling voice, data, text, facsimile and image communication today. In this research a detailed study is carried out on wired digital EPABX system. However, during the study of wired digital EPABX system, several technical problems are encountered. Therefore a new design is proposed that replaces the wired digital EPABX system with the wireless digital EPBAX system using the DEeT (Digital Enhanced Cordless Telecommunications) cordless technology. DEeT is a WLL (Wireless Local Loop) system, based on the DEeT standard. The DEeT offers high quality access technology recognized by more and more users, regulators, standardization bodies, network operators and equipment manufacturers. It has proven multiple applicability as a network access in residential, offices, business and public environments showing easy mobility, speech quality comparable to wireless telephony. It can also offer high level of security through advanced digital technology and encryption, which allows for high subscriber densities, flexible bandwidth allocation, multiple service support, cost competitiveness, flexible deployment and simple installation. A sincere effort is made in understanding the operating principle involved with regard to implementation of the DECT cordless technology. This research findings are: • Reduction of 2% -15% crosstalk from wired digital EPABX systems. • The line lock-out is completely absent in wireless digital EPABX system. • The lines out of order reduce from 0% - 12% from wired digital EPABX systems. • The cost per line reduces from 10.38% - 25.62% from wired digital EPABX systems. • Finally, in this dissertation, an attempt is made to a) Design a new wireless digital EPBAX system for small geographical area such as university campus. b) Implemented the wireless designed digital EPBAX system. c) Analysed its performance and compared with wired counter part.
