DETERMINATION OF OPTIMUM NUMBER OF TRUNK LINES FOR CORPORATE NETWORK BACKBONE IN NIGERIA

Abstract

The problem of determining the optimum number of telecommunication trunk lines subscribers' common equipment) for a given average traffic intensity is contributory, among other things, to the problem encountered in providing cost effective and high quality telecommunication services to corporate network users. Therefore, an accurate means of determining the optimum number of trunk lines required to be leased from public network backbone is vital. It is usual, in the developed countries, to assume a reliable public network while determining the optimum number of trunk lines required to be leased. In most developing countries, this assumption will lead to errors in determining the number of trunk lines required to be leased. In this paper, therefore, a template is developed for corporate network providers in Nigeria for the determination of the precise number of required trunk lines based on the concept of equipment failure and restoration.
