Planning of telephone network is the process of determination of numbers, sizes, locations and boundaries of exchanges, as well as numbers and arrangements of junctions between them, in such way to minimize total cost, and meet performance requirements. An important feature of planning is the prediction of demand for facilities far in advance. So that the service provider finds the conditions under which adequate service is given to the subscriber while the economical use is made of the facilities providing the service. The traffic engineering is a useful and important science, which is used to manage the activities of the switching and transmission departments in telephone authorization and guides to the optimum use of the network. In the present work a short-term forecast model for telephone traffic volumes in Khartoum telephone network (as case study) is investigated using a method based on Kalman filter model described by two dimensional linear model including a white noise process. In order to achieve this goal, object oriented C++ programs are developed. The data needed for the initialization of the filter is estimated and analyzed using a specially designed program because of the unavailability of the real telephone traffic data in the case study. The filter parameters needed by the model are calculated and the traffic forecast patterns with minimum errors are obtained for each exchange in greater Khartoum. The obtained results are displayed in graphical mode, these results are in good agreement with the theoretical one. The accuracy of the results depends on the degree of precision of data used. The forecast error is found to be in the range between 0.4 and 8.13 percent.
