Endpoint mapping in a communication system using serial signal sensing
First Claim
Patent Images
1. A method, comprising:
- in a communication system comprising endpoints, wherein each endpoint comprises a computer or a network switch and wherein the endpoints connect to one another using cable connections, injecting one or more test signals to a mid-point of a cable connection, which has first and second ends and is potentially connected to a first endpoint at the first end and to a second endpoint at the second end;
performing one or more serial measurements, which sense a voltage that falls across an electronic component inserted in series with the cable connection at the mid-point, so as to sense the test signals; and
based on the serial measurements, deciding which of the first and second endpoints are indeed connected to the cable connection.

Abstract
A method in a communication system (20) including endpoints (24) that connect to one another using cable channels, includes injecting one or more test signals to a cable channel, which has first and second ends and is potentially connected to a first endpoint at the first end and to a second endpoint at the second end. One or more serial measurements are performed on the cable channel so as to sense the test signals. Based on the serial measurements, a decision is made as to which of the first and second endpoints are indeed connected to the cable channel.

13. Apparatus, comprising:
-
an interface, which is coupled to connect to a communication system comprising endpoints, wherein each endpoint comprises a computer or a network switch and wherein the endpoints connect to one another using cable connections; and test circuitry, which is configured to inject via the interface one or more test signals to a mid-point of a cable connection, which has first and second ends and is potentially connected to a first endpoint at the first end and to a second endpoint at the second end, to perform one or more serial measurements, which sense a voltage that falls across an electronic component inserted in series with the cable connection at the mid-point, so as to sense the test signals, and, based on the serial measurements, to decide which of the first and second endpoints are indeed connected to the cable connection. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A keystone jack, comprising:
-
a receptacle comprising at least a pair of receptacle terminals for connecting to a wire pair in a mating keystone plug; at least a pair of rear interconnection terminals connected to the pair of the receptacle terminals; a sense interface, which comprises an electronic component that is inserted in series between the pair of receptacle terminals and the pair of the rear interconnection terminals, for serially sensing at least one test signal on the wire pair by sensing a voltage that falls across the electronic component; and an injection interface, which is coupled to inject the at least one test signal to the wire pair on at least one respective side of the sense interface. - View Dependent Claims (26, 27, 28)
