In an administration system for a public switched telephone network, a service analysis system is provided for proactively analyzing the working status of customer network facilities including a communication line in a communication cable associated with a customer. The service analysis system includes an automatic line insulation test (ALIT) system testing the communication line in the communication cable associated with the customer producing trouble indicators indicating a potentially defective communication line, and a mechanized loop testing (MLT) system testing groups prioritized for the communication line. The service analysis system also includes a data processor filtering the trouble indicators received from the ALIT system from predetermined communication services associated with the communication line that provide potentially false trouble indicators producing valid trouble indicators, and generating a list of the valid trouble indicators to be considered when determining whether the communication line is potentially defective. The data processor generates a report to be used for examining the potentially defective communication line using the prioritized groups.

[ We claim:] [1.] In an administration system for a public switched telephone network which includes an attendant station for receiving service requests and collecting customer information, credit verification means, service order processing (SOP) means for creating and distributing service orders for processing by downstream processing systems including at least one of a Service Order Analysis and Control (SOAC) means, a Computer System for Mainframe Operations (COSMOS) means, SWITCH means, and Loop Facility Assignment and Control System (LFACS) means; and Adjunct Processor (AP) means having storage for storing data including Living Unit (LU) data, network facility data and Telephone Number (TN) data, a method of proactively analyzing the working status of customer network facilities including a communication line in a communication cable associated with a customer, comprising the steps of:(a) performing a first level test of the communication line in the communication cable associated with the customer producing trouble indicators indicating a potentially defective communication line;(b) filtering the trouble indicators from predetermined communication services associated with the communication line that provide potentially false trouble indicators producing valid trouble indicators;(c) generating a list of the valid trouble indicators to be considered when determining whether the communication line is potentially defective;(d) generating an end to end description of the communication line to be tested;(e) grouping the valid trouble indicators that have common network elements in groups;(f) prioritizing the groups for performing a second level test of the communication line;(g) testing the groups prioritized for the communication line;(h) discarding the groups that are in a satisfactory status responsive to predetermined criteria;(i) prioritizing the groups that are potentially defective indicating the potentially defective communication line generating prioritized groups; and(j) generating a report to be used for examining the potentially defective communication line using the prioritized groups.
