Abstract

Systems and methods for detecting a patch cord connection are presented. The insertion of a patch cord into a device jack physically closes a circuit, thereby permitting determination of the patch cord connection. The connection of only one side of a patch cord to a jack is able to be determined. In addition, a particular jack with which a patch cord is connected is able to be determined.

Claims

1. A system for detecting a patch cord end connection comprising:

a patch cord, the patch cord having a first patch plug electrically connected at a first end and a second patch plug electrically connected at a second end, the first patch plug and second patch plug each having a ninth wire pin;

a first port; and

a second port, each of the first port and second port having a set of ninth wire contacts, each of the set of ninth wire contacts having a first portion and a second portion wherein the contacts are configured such that the first portion and second portion of each set of ninth wire contacts for the first port and second port are electrically isolated from each other when there is no plug inserted into the port and further configured such that;

a circuit is completed between the first portion and second portion of the set of ninth wire contacts of the first port when the first patch plug is inserted into the first port via the ninth wire pin of the first patch plug;

a circuit is completed between the first portion and second portion of the set of ninth wire contacts of the second port when the second patch plug is inserted into the second port via the ninth wire pin of the second patch plug; and

a circuit is completed between the set of ninth wire contacts of the first port and the set of ninth wire contacts of the second port when the first plug is inserted into the first port and the second plug is inserted into the second port.

2. The system of claim 1 wherein the first and second portions of each of the set of ninth wire contacts for the first port and second port are connected to a connectivity detector which can determine whether the first and second portions of the set of ninth wire contacts form an open or closed circuit.

3. The system of claim 2 wherein at least one of the first portion and second portion of the set of ninth wire contacts of the first port is connected to a first transceiver and at least one of the first portion and second portion of the set of ninth wire contacts of the second port is connected to a second transceiver, the first transceiver configured to communicate with the second transceiver.

4. The system of claim 3 wherein the set of ninth wire contacts for each of the first port and the second port each also have a third portion, the third portion electrically isolated from at least one of the first portion or the second portion.

5. The system of claim 4 wherein the first portion, the second portion, and the third portion of each of the set of ninth wire contacts for the first plug and the second plug are substantially parallel.
