ABSTRACT:
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.
