    Telecommunications network operators are on a constant challenge to provide new services which require ubiquitous broadband access. In an attempt to do so, they are faced with many problems such as the network coverage or providing the guaranteed Quality of Service (QoS). Network planning is a multi-objective optimization problem which involves clustering the area of interest by minimizing a cost function which includes relevant parameters, such as installation cost, distance between user and base station, supported traffic, quality of received signal, etc. On the other hand, service assurance deals with the disorders that occur in hardware or software of the managed network. This paper presents a large number of multicriteria techniques that have been developed to deal with different kinds of problems regarding network planning and service assurance. The state of the art presented will help the reader to develop a broader understanding of the problems in the domain

    A Practical implementation of high-speed communication using digital subscriber line technology

    This thesis creates a plan for the practical implementation of high-speed communication for residences and businesses. By implementing low-cost, high-speed communication on a global scale, tremendous benefits can occur in areas such as Internet communication, interactive multimedia, telecommuting, and distance learning. Despite several successful trials of various high-speed communication technologies, many barriers remain before deployment can occur to the general public. This thesis proposes a plan to bridge the gap between theoretical test studies and global implementation. This thesis evaluates three communication systems as potential solutions for high-speed communication and selects one system as the solution. The three candidate systems are Digital Subscriber Line technologies (collectively referred to as xDSL), Integrated Services Digital Network (ISDN), and cable modem. The chosen technology solution, xDSL, allows twisted-pair copper wire (i.e. telephone lines) to be used for high-speed communication. The choice of xDSL as the technology solution is based on many factors, all of which correspond to practicality. The intent of this thesis is not the promotion of xDSL; rather, the primary objective is to create a plan to quickly and globally implement a low-cost, high-speed communication infrastructure for residences and businesses

    The growth and pace of any industry is a veritable estimation of its viability. The telecommunications industry all over the world is ever burgeoning. Its growth is buoyed by development and technologies. These innovations do not necessarily have to instantaneously supplant the old rather they are procedurally applied to the existing network in the form of Upgrades and Expansion efforts. This paper appraises these grafting processes. It introduces the subject matter, highlights the performance capabilities and usage constraints of a variety of switching and transmission equipment. It also gives insight into the on-going grafting efforts in NITEL
