Abstract

A system for identifying interconnections between individual points in a communications network of the kind in which includes a plurality of multiple conductor links, individual conductors of which are selectively terminated and interconnected at corresponding individual terminals of terminal blocks; a controller broadcasts over a test network that includes the terminal blocks an inquiry that identifies a starting individual conductor to supervisors associated with the terminal blocks; the supervisor associated with the terminal block that terminates the starting conductor applies the inquiry to the individual terminal that corresponds to the starting individual conductor for transmission on the communications network, and each supervisor reports to the controller over the test network the identitites of any one or more individual terminals of its associated terminal block that detect the inquiry; whereby interconnections between the starting conductor and one or more other individual conductors in the communications network are identified.

Claims

1. A system for identifying interconnections between individual conductors in a communications network of the kind in which includes a plurality of multiple conductor links, individual conductors of which are selectively terminated and interconnected at corresponding individual terminals of terminal blocks, comprising

a controller for broadcasting over a test network that includes said terminal blocks an inquiry that identifies a starting individual conductor, and

supervisors associated with said terminal blocks,

the supervisor associated with the terminal block that terminates said starting conductor applying said inquiry to the individual terminal that corresponds to said starting individual conductor for transmission on said communications network,

each supervisor reporting to said controller over said test network identities of any one or more individual terminals of its associated terminal block that detect said inquiry, whereby interconnections between said starting conductor and one or more other individual conductors in said communications network are identified.

2. The system of claim 1 wherein at least some of said terminal blocks are physically located in proximity to each other, said test network comprising a secondary network that includes only said some terminal blocks.

3. The system of claim 2 wherein said secondary network includes a controller for passing inquiries and reports between said test network controller and supervisors on said secondary network.

4. The system of claim 3 further comprising

a plurality of said secondary networks, and

a primary network that includes said test network controller and the secondary controllers of said secondary networks.

5. The system of claim 4 wherein an inquiry also identifies the terminal block that terminates said individual conductor and the secondary controller for the secondary network that includes said identified terminal block,

whereby said inquiry is transmitted on said primary network to said identified secondary network controller, and then is transmitted by said secondary network controller over its secondary network to said identified terminal block.

6. The system of claim 5 wherein said terminal blocks are disposed in one or more rooms on at least one floor of at least one building, and said inquiry from said test network controller identifies said starting conductor includes addresses for the building, floor, room, and supervisor of the terminal block associated with said conductor, and further includes an address for said conductor and an inquiry message.

7. The system of claim 6 wherein said inquiry further includes a command that instructs the supervisor associated with said starting conductor to place said inquiry on the conductor and that instructs all supervisors to then listen on the conductors of the terminal blocks with which they are associated for said inquiry.

8. The system of claim 6 wherein said identified secondary controller broadcasts the request on its secondary network, the request including addresses for the supervisor of the terminal block associated with said conductor and for said conductor, and said inquiry message.

9. The system of claim 8 wherein said inquiry from said secondary controller further includes a command that instructs the supervisor associated with said starting conductor to place said inquiry on the conductor and that instructs all supervisors to then listen on the conductors of the terminal blocks with which they are associated for said inquiry.

10. The system of claim 8 wherein the report from each reporting supervisor includes addresses for that supervisor and for said conductor that receives said inquiry over the communications network, and said inquiry message.

11. The system of claim 10 wherein each secondary network controller collects and temporarily stores reports from supervisors on its secondary network.

12. The system of claim 11 wherein each secondary network controller sends said collected reports to said test network controller over said primary network in a report that includes

a header including the address of said secondary network controller and the addresses of its building and floor, and

one or more words, each word including the addresses of the reporting supervisors, the addresses of the individual conductors that received said inquiry over the communications network, and said inquiry message.

13. The system of claim 12 wherein said reports from said supervisors also indicate a status of the supervisors, and said one or more words each further include said status.

14. The system of claim 5 wherein said primary and secondary networks are local area networks.

15. The system of claim 14 wherein said local area networks are token ring networks.

16. The system of claim 1 further comprising a processor for causing said controller to make said inquiry and for responding to reports from said supervisors to generate a list of all individual conductors that are interconnected to said starting individual conductor.

17. The system of claim 16 further comprising a data base associated with said processor for storing said list.

18. The system of claim 1 wherein at least one of said supervisors is formed as an integral unit with its associated terminal block.

19. The system of claim 1 wherein at least one of said supervisors is adapted to be attached to its associated terminal block.

20. The system of claim 19 wherein said terminal block is a punch down block.

21. The system of claim 20 wherein said punch down block is a 66M punch down block.

22. The system of claim 1 wherein each said individual conductor includes a pair of wires.

23. The system of claim 1 wherein said communications system is a telephone system for transmission of voice and data messages between subscribers on the network via said individual conductors.

24. A method for identifying interconnections between individual points in a communications network of the kind in which includes a plurality of multiple conductor links, individual conductors of which are selectively terminated and interconnected at corresponding individual terminals of terminal blocks, comprising

broadcasting from a controller over a test network that includes said terminal blocks an inquiry that identifies a starting individual conductor,

applying said inquiry, at the terminal block that terminates said starting conductor, to the individual terminal that corresponds to said starting individual conductor for transmission on said communications network, and

reporting from said terminal blocks to said controller over said test network identities of any one or more individual terminals of its associated terminal block that detect said inquiry, whereby interconnections between said starting conductor and one or more other individual conductors in said communications network are identified.
