Abstract:
A method of testing an IDSL communications line comprising the steps of:querying transmission elements sequentially by a test set within an IDSL communications line and sending high frequency test tones and determining if a current transmission element is less than a predetermined number, and if not, moving the test set into an idle mode where the test set waits for a response and a change in environment and loop back occurs; if the current transmission element is less than a predetermined number, waiting a predetermined period of time after querying a transmission element for a correct response; if a correct response is received, then querying the next transmission element for its existence; if a correct response has not been received within a predetermined period of time, considering the last network element as identified; periodically querying the network element identified as the last network element to determine status changes such that if there is no response indicative of a network terminator, querying again to determine if the network element has exceeded a maximum allowable number of elements in the transmission line, and if not exceeded, querying periodically for status changes; and identifying and updating the configuration of the IDSL communications line based on the received responses.
