Abstract: A system and method of estimating wideband performance characteristics of a telecommunications subscriber loop by identifying and inventorying broadband inhibitors that are present in the subscriber loop. The method begins by inventorying a client computer and associated components. Then, a voice band modem call from a modem associated with the client computer is placed to a remote access server (RAS) under the control of a server computer. Next, once the connection is established between the client computer and the RAS, the RAS extracts modem training and line probing signals received from the client computer modem. In addition, the client computer transmits its inventory of components to the RAS. The RAS then analyzes the received signals and component inventory to identify and inventory potential wide band inhibitors that are present in the subscriber loop being analyzed.
