US Patent:

6487276, Nov 26, 2002

Filed:

Sep 30, 1999

Appl. No.:

09/410237

Inventors:

Joseph S. Rosen - Chicago IL
Susan E. McGill - Barrington IL

Assignee:

Teradyne, Inc. - Boston MA

International Classification:

H04M 124

US Classification:

379 104, 379 2701, 379 2703, 379 24, 379 2901

Abstract:

A method tests a subscriber line. The method includes providing a classifier to predict a performance characteristic of the line based at least in part on a value of an auxiliary variable. Each value of the auxiliary variable represents a property of the line. The method also includes performing electrical measurements on the subscriber line, using the measurements to predict a value of the auxiliary variable, and predicting the performance characteristic of the line. The act of predicting the characteristic applies the classifier to the predicted value of auxiliary variable.

International Classification:

H04B 720

US Classification:

455424

Abstract:

The present invention provides a method and apparatus for gathering, organizing and using information related to the operation and maintenance of a wireless communication system (10) such as a cellular communication system. In accordance with preferred embodiments of the present invention, system information is organized facilitating a causal analysis of the operation of the cellular communication system to achieve desired operating effects. In accordance with further preferred embodiments, causal data is input to a causal analysis knowledge base by modifying a graphic cause and effect diagram (100). The cause and effect diagram (100) maps and models the data within the knowledge base and without requiring the user to possess specialized knowledge of the structure or operation of the knowledge base.
