Abstract: A technician evaluates each of the pieces (22, 24, 26 and 28) of building infrastructure equipment in a distribution network (18) by accessing a data base (34) to obtain a record (36.sub.i) for the selected equipment piece. Each record contains an identification for the selected equipment piece as well as its operating tolerance specification. A comparison of the actual operating parameters to the operating tolerance specification reveals whether the piece of equipment is operating properly. Should the equipment have an operating parameter outside an acceptable range, the out-of-compliance data entry value is visually flagged and the impact of that piece of equipment on the network is assessed to determine the appropriate corrective action.
