ABSTRACT:
From time-to-time, the telephone outside loop plant is severely damaged as a result of some catastrophe, such as a hurricane. To facilitate the repair and identification of such damage, a facility is provided which rapidly assesses and outputs to a terminal the extent of such damage. The rapid assessment is made possible by taking advantage of information that may be obtained from a number of different sources, in which the extent of the damage may be determined from such information.
