Abstract
A method and system is disclosed for testing an IDSL communications line. Transmission elements are queried sequentially within an IDSL communications line. A predetermined period of time is waited after querying a transmission element for a correct response. If a correct response is received, the next transmission element is queried for its existence. Configuration of the IDSL communications line is identified based on the received responses.
Claims25
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.

- identifying and updating the configuration of the IDSL communications line based on the results from the querying steps and any received responses.

A test set for testing an IDSL communications line comprising:
- an interface circuit for interfacing with an IDSL communications line;
- and
- a processor connected to said interface circuit for transmitting a query command as high frequency test tones along the IDSL communications line and querying transmission elements sequentially along the communications line 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, and if the current transmission element is less than a predetermined number, querying transmission elements after a predetermined period of time such that if a correct response has not been received within a predetermined period of time, considering the last network element as identified, wherein said processor is operative for determining status changes such that if there is no network termination 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 to identify and update the configuration of the IDSL communications line based on the received responses.
A system for testing an IDSL communications line comprising;
- a communications line forming an IDSL communications link having a plurality of transmission elements, a copper loop and network terminator connected thereto;
- a test circuit connected to said communications line for:
- querying the transmission elements sequentially 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 for a correct response from a transmission element, 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 when a last 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.
