In the initial stage of ISDN, ISDN switches (hosts) are installed in the main areas and the other areas are covered by remote systems. As the number of subscribers of a remote system increases this remote system will be replaced with a host, considering costs of hosts and remote systems. We formulate the problem of finding an optimal deployment strategy of ISDN facilities, mainly switch and remote systems, over a planning horizon using an integer programming and develop a heuristic algorithm for the problem. The heuristic algorithm developed here uses a backward approach from the final time of the planning horizon and can be efficiently implemented for determining the ISDN switch installation time
