ABSTRACT:
The present invention provides a digital loop carrier (“DLC”) information system that provides information for use in a central office. The DLC information system includes four related databases. A DLC system database provides information about DLC systems, a multiplexer database provides information about multiplexers associated with the DLC systems, an equipment location database provides information about the location of the DLC systems and a test pair database provides information about the test pairs used to test the DLC systems. The information in each of the databases is related using the system identifiers for the DLC systems.
