Inferring physical layer connection status of generic cables from planned single-end connection events
A work order is generated. The work order comprises a first work order step specifying that a port of a first network element is to be connected to a port of a second network element using a cable. The first and second network elements are configured to detect when connections are made at the specified ports of the first network element and the second network element. A management system is configured to update information it maintains to indicate that there is a connection between the specified port of the first network element and the specified port of the second network element if connections made at the specified ports of the first and second network elements are detected during a period in which the first work order step of the first work order is expected to be performed. A similar technique can be used for disconnecting a cable.
1. A method comprising:
generating a first work order comprising a first work order step specifying that a port of a first network element is to be connected to a port of a second network element using a cable;
detecting, using the first network element, when a connection is made at the specified port of the first network element using the cable, and reading physical layer information about the cable from a first connector of the cable; and
determining, by an electronic work order application, if connection of the cable to the first network element complies with the first work order based on the physical layer information read from the first connector.
2. The method of claim 1 , further comprising, altering a visual indicator at the specified port of the first network element in response to determining that connection of the cable to the first network element complies with the first work order.
3. The method of claim 1 , further comprising:
detecting, using the second network element, when a connection is made at the specified port of the second network element, and reading the physical layer information about the cable from a second connector of the cable; and

4. The method of claim 1 , wherein the first network element and the second network element comprise first and second managed network elements, respectively.
5. The method of claim 1 , wherein the first and second network elements comprise at least one of a patch panel, an optical distribution frame, a splitter tray, a switch, and a router.
6. The method of claim 1 , wherein each of the first and second network elements includes at least one of EEPROM-based PLM technology and RFID PLM technology.
7. The method of claim 1 , wherein the cable comprises at least one of a fiber optic cable and a copper cable.
8. The method of claim 1 , wherein the physical layer information comprises an identifier.
9. The method of claim 1 , wherein the cable comprises a storage device that stores the physical layer information.
10. The method of claim 3 , further comprising, altering a visual indicator at the specified port of the second network element in response to determining that connection of the cable to the first network element complies with the first work order.
11. A system comprising:
a first network element comprising at least one port, wherein the first network element is configured to detect when a cable is connected to the port of the first network element;
a second network element comprising at least one port, wherein the second network element is configured to detect when a cable is connected to the port of the second network element; and
a management system communicatively coupled to the first network element and the second network element;
wherein the management system is configured to generate a first work order comprising a first work order step specifying that the port of a first network element is to be connected to the port of the second network element using the cable;
wherein the management system is configured to detect, using the first network element, when a connection is made at the specified port of the first network element using the cable, and read physical layer information about the cable from a first connector of the cable; and
wherein the management system is configured to determine if connection of the cable to the first network element complies with the first work order based on the physical layer information read from the first connector.
12. The system of claim 11 , further comprising a visual indicator at the specified port of the first network element, wherein the management system is configured to alter the visual indicator at the specified port of the first network element in response to determining that connection of the cable to the first network element complies with the first work order.
13. The system of claim 11 , further comprising:
wherein the management system is configured to detect, using the second network element, when a connection is made at the specified port of the second network element, and read the physical layer information about the cable from a second connector of the cable; and
wherein the management system is configured to determine if connection of the cable to the second network element complies with the first work order based on the physical layer information read from the second connector.
