Abstract

An apparatus and method, using a computer, for the efficient generation of a wiring map of the connectivity between two sets of terminals at different locations which have established communication links between respective terminals at the two locations. A single at a first location uniquely identifies each of the terminals, by code, frequency, sequence of connection or the like, and is transmitted to a respective terminal at the second location via a respective communication link. The terminals at the second location are sampled and the presence of the transmitted signal correlated to the identity of the first terminal. The correlation may be direct, as by unique terminal identifier, or by a comparison of data bases stored by computers. The computer-based correlation is used to generate a map of the limited terminals.

Claims

1. A method, using computer means, of correlating the respective locations of a plurality of first terminals comprising communications jacks, connections and devices installed at first locations, each of said first terminals being connected by a communications medium to respective second terminals at a second location, comprising the steps of:

generating a signal at each first terminal, transmitting each said signal from a sequence of respective first terminals to respective ones of said second terminals,

recording first information correlating the sequence of said signal transmission and the location of each first terminal,

detecting each said transmitted signal at each respective second terminal,

identifying in said computer means the sequence in which said second terminals receive said signal with second information correlating the sequence of said signal detection and the location of said second terminals,

comparing in said computer means said first information obtained in said recording step and said second information obtained in said identifying step to create a third information which correlates the physical location of each first terminal to the physical location of a corresponding second terminal, and

providing a map of the communications medium which connects said first and second terminals.

2. The method of claim 1 wherein said transmission sequence is recorded as a function of time of the day.

3. The method of claim 1 wherein said generating step comprises generating from a common source a unique signal at each first location.

4. In a telecommunications system having first communications terminals at a plurality of first locations, second communications terminals at one or more second locations and communications media connecting a respective pair of first and second terminals, said system further comprising:

first location means connectable in a first sequence to each of said first terminals and operative to generate a signal at each first terminal for transmission via said communications media to said respective second terminal, to identify each said first terminal with said first sequence and to store said identity of said first terminals with said first sequence;

second location means connectable to said second communications terminals and operative to record a second sequence of second terminals in which said signal is received and the physical location of each second terminal on which said signal is received; and

computer means for correlating the first sequence in which said signal generator means is connected to said first terminals and the second sequence in which said transmitted signal output is received at said second communication terminals; and

means for generating a map comprising the identity of the location of each first communications point correlated to the identity of its corresponding second point whereby each of said second communication terminals may be identified with the physical location of each first communication terminal to which it is connected.

5. The system of claim 4 wherein said first location means further comprises a first data base means for generating a data base that identifies said first terminals with said first sequence in which said signal generator means is connected thereto and said second location means includes means for receiving said signal at each of said second communication terminals and generating a second data base identifying said second sequence in which each second communications terminal receives said signal.

6. The system of claim 5 further including a means for correlating said first and second data bases whereby the physical connections of said first and second terminals is obtained.

7. A method of correlating the respective locations of a plurality of first physically collocated terminals at a first physical location, each of said first terminals being identifiable by a respective one of a plurality of first unique identifiers and being connected by a communications medium to respective second terminals at second physically dispersed locations, each of said terminals being identifiable by a respective one of a plurality of second unique identifiers, comprising the steps of:

establishing the existence of a connection between a first terminal and a second terminal by said communications medium;

generating a unique signal at each first and second location, said signal comprising said first and second unique identifier, respectively;

transmitting each said first unique signal from said first terminals at said first location to a respective one of second terminals at a respective second location,

detecting and storing said transmitted first unique identifier at said respective physically dispersed second location,

correlating each said detected first unique identifier with said generated second unique identifier, and

generating a map of the communications medium which connects terminals at said first and second locations, said map comprising the identity of said first physically collocated terminals and the identity of said physically disposed location of said second terminals.

8. The method of claim 7 wherein said unique identifiers comprise alpha/numerics.

9. The method of claim 8 wherein said alpha/numerics are encoded.

10. The method of claim 7 wherein said identifiers are correlated to physical locations of said first and second terminals.

11. Apparatus for correlating the respective locations of a plurality of first collocated terminals, each of said first terminals being identifiable by one of a plurality of first unique identifiers and being connected by a communications medium to respective second terminals at second physically dispersed locations, the physical location of each of said second terminals being identifiable by one of a plurality of second unique identifiers, comprising:

first means for generating a first unique signal at each first location, said signal comprising a first unique identifier;

means for transmitting each said first unique signal from its respective first terminal to a respective second terminal,

means for detecting said transmitted first unique identifier at its respective second terminal,

second means for generating a second unique signal at each second location, said second unique signal being related to said second unique identifer, and

computing means storing said detected first unique identifier and for correlating each first unique identifier with said second unique identifier wherey a map is created of the physical location of each second terminal at which said first identifier was detected and the identity of the respective first terminal to which it is connected.

12. The apparatus of claim 11 wherein said second generating means comprises a scanner means.

13. The apparatus of claim 11 wherein said second generating means comprises a keyboard.

14. The apparatus of claim 11 wherein said first terminals comprise at least one of jacks, connections and devices installed at said first location.

15. The apparatus of claim 11 further comprising at said second location means for storing said detected unique identifier.

16. The apparatus of claim 11 further comprising at said second location means for generating a map of the connections between said first and second terminals.
