## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. application Ser. No. 14/477,231, now U.S. Pat. No. 9,407,510, filed Sep. 4, 2014, and titled “PHYSICAL LAYER SYSTEM WITH SUPPORT FOR MULTIPLE ACTIVE WORK ORDERS AND/OR MULTIPLE ACTIVE TECHNICIANS”, which claims the benefit of U.S. Provisional Patent Application Ser. No. 61/873,610, filed on Sep. 4, 2013, wherein the contents of all of the foregoing applications are hereby incorporated herein by reference.


BACKGROUND
One common use of a physical layer management (PLM) system is to guide a technician in moving, adding, or changing a connection made at a patch panel or other device where connections are made using cables. This is commonly done as a part of a larger “work order” that includes one or more steps.
In one common implementation, the patch panel includes a light emitting diode for each port of the patch panel and a controller that interacts with a remotely located management system. To guide a technician in performing a step of a work order that affects a particular port of the patch panel, the management system can illuminate (or otherwise actuate) the light emitting diode that is associated with that port in order to visually identify the port for the technician. This is done to assist the technician in locating the correct port. That is, the light emitting diode is used to provide a visual indication of the affected port.
Such systems are typically designed to be used to guide a single technician in performing a single work order at a time. That is, such systems are not designed to guide multiple technicians in performing multiple work orders.

DETAILED DESCRIPTION
FIG. 1 is a block diagram of one exemplary embodiment of system 100. The system 100 is also referred to here as a “physical layer management” (PLM) system 100.
In the exemplary embodiment shown in FIG. 1, the PLM system 100 is used to guide technicians in moving, adding, or changing connections made in a network 102. The PLM system 100 can also be used to track physical layer information related to the network 102. As used herein, “physical layer information” comprises information about the cabling, connections, and communication links that exist in the network 102.
In the exemplary embodiment shown in FIG. 1, the network 102 includes various network elements or devices to which cables are connected. In the exemplary embodiment shown in FIG. 1, the network 102 includes a managed network element or device 104 that includes a plurality of ports 106 to which cables 108 can be attached.
More specifically, in the exemplary embodiment shown in FIG. 1, the managed device 104 comprises a patch panel (and is also referred to here as “managed patch panel” 104). The managed patch panel 104 is described here, in this exemplary embodiment, as being designed for use with copper twisted-pair CAT-5, 6, and 7 cables typically used to implement ETHERNET local area networks. The managed device can be implemented in other ways (for example, as an optical distribution frame, splitter tray, switch, router, etc.). Also, the managed device 104 can be implemented for use with other types of cables (for example, other types of copper cables or fiber optic cables).
The managed device 104 includes a controller or other programmable processor 110 that is configured to communicate with a management system 112 over the network 102. The managed device 104 also includes a network interface 111 for communicatively coupling the managed device 104 (more specifically, the controller 110) to the network 102 and, ultimately, the management system 112. In the example shown in FIG. 1, the controller 110 and the network interface 111 are communicatively coupled to the network 102 and the management system 112 by including a respective “management” or “non-service” port 114 in the managed device 104. The management port 114 is separate from the “service” ports 116 of that device 104. However, the controller 110 in the managed device 104 can be communicatively coupled to the network 102 using one or more of the “service” ports 116.
The managed device 104 includes one or more visual indicators 118 that are associated with each service port 116 of the managed device 104. In this exemplary embodiment, each visual indicator 118 is implemented using a light emitting diode (LED). Each LED 118 is coupled to the controller 110 in the managed device 104 so that the controller 110 (more specifically, the software executing on the controller 110) can control the LED 118.
In this example, the managed device 104 is configured so that each LED 118 can provide multiple visual indications. These multiple visual indications can be provided by having each LED 118 display multiple colors, blink at multiple rates, and/or blink in multiple patterns. Multiple visual indications can be provided in other ways.
A visual indication is provided in order to assist a technician in locating the associated service port 116 of the managed device 104.
In this example, the managed device 104 also includes, for each of the service ports 116, a storage device interface 120 that is configured so that, when a cable 108 is attached to that port 116, information can be read from any storage device 122 attached to the cable 108 by the controller 110 and communicated to the management system 112, which stores and/or updates information in a database or other data store 131 maintained by the management system 112.
In one example, each storage device interface 120 comprises a contact-based storage device interface that is configured for use in reading information from an Electrically Erasable Programmable Read-Only Memory (EEPROM) attached to each cable. In another example, each storage device interface 120 comprises a radio frequency identifier (RFID) interface that is configured for use in reading information from an RFID tag attached to a cable 108. That is, in such an RFID example, contact-less interfaces are used for reading information from the storage devices 122 attached to the cables 108 and each storage device 122 is implemented using an RFID tag.
The managed device 104 can also include a plurality of presence sensors 121, each of which is configured for use in determining if a cable is attached to one of the service ports 116. Such presence sensors 121 can be used in connection with the storage device interface 120 described above (for example, to determine when a cable 108 has been connected to a service port 116 and/or to determine if a cable 108 that does not have a storage device 122 attached to it has been connected to a service port 116). Also, such presence sensors 121 can be used to infer information about connections made using the managed device 104 instead of or in addition to using information read from storage devices 122 attached to cables 108.
Power can be supplied to the active components of the managed device 104 in various ways (for example, by connecting the managed patch panel 104 to the standard AC power grid, using Power-Over-Ethernet technology, or in other ways).
In the exemplary embodiment shown in FIG. 1, the management system 112 is implemented as software that executes on one or more computers 124.
In the exemplary embodiment shown in FIG. 1, each computer 124 comprises one or more programmable processors 126 for executing the software. The software comprises program instructions that are stored (or otherwise embodied) on or in an appropriate non-transitory storage medium or media 128 (such as flash or other non-volatile memory, magnetic disc drives, and/or optical disc drives) from which at least a portion of the program instructions are read by the programmable processor 126 for execution thereby. Although the storage media 128 is shown in FIG. 1 as being included in, and local to, the respective computer 124, it is to be understood that remote storage media (for example, storage media that is accessible over the network 102) and/or removable media can also be used. Each computer 124 also includes memory 130 for storing the program instructions (and any related data) during execution by the programmable processor 126. Memory 130 comprises, in one implementation, any suitable form of random access memory (RAM) now known or later developed, such as dynamic random access memory (DRAM). In other embodiments, other types of memory are used. Each computer 124 also includes one or more network interfaces 132 for communicatively coupling the computer 124 to the network 102.
In the example shown in FIG. 1, the management system 112 further includes an electronic work order application 134. The electronic work application 134 is used to construct electronic work orders 136. Each electronic work order 136 specifies one or more steps that are to be carried out by a technician at a particular location. For example, an electronic work order 136 can indicate that one or more connections implemented using the service ports 116 of the managed device 104 should be added, removed, and/or changed. For steps that involve adding, removing, and/or changing connections made at the service ports 116 of the managed device 104, the information that is read from the associated storage devices 122 and communicated to the management system 112 can be used by the electronic work order application 134 to verify that the specified connection has been added, removed, and/or changed correctly.
As described in more detail below, the visual indicators 118 associated with the service ports 116 of the managed device 104 can be actuated in order to guide a technician in carrying out the steps of electronic work orders 136.
In this example, each electronic work order 136 is communicated to a portable device 138 that is carried by a technician that has been assigned to carry out that electronic work order 136. In this example, the portable device 138 is implemented using smartphone (and is also referred to here as smartphone 138). However, it is to be understood that each portable device 138 can be implemented in other ways (for example, using tablet computers, laptop computers, or similar devices).
In this example, each smartphone 138 is configured to execute a mobile application 140. The mobile application 140 is configured to communicate with the electronic work order application 134 and the management system 112 and to receive the electronic work orders 136. The mobile application 140 comprises program instructions that are stored (or otherwise embodied) on or in an appropriate non-transitory storage medium or media from which at least a portion of the program instructions are read by at least one programmable processor included in the smartphone 138 for execution thereby.
Each electronic work order 136 can be communicated wirelessly to the smartphone 138 over the Internet (for example, via a cellular or wireless local area network to which the smartphone 138 is wirelessly connected). Each electronic work order 136 can also be communicated to the smartphone 138 in other ways (for example, using a wired connection with the smartphone 138).
In the exemplary embodiment shown in FIG. 1, the system 100 is configured to support multiple active work orders 136 and multiple technicians working at the device 104 at the same time. The example shown in FIGS. 1 and 2 is described as involving two active work orders 136 and two portable devices 138; however, it is to be understood that this is merely exemplary, and that different numbers of multiple active work orders and portable devices 138 can be used.
The management system 112 and managed device 104 are configured so that multiple visual indications can be provided at the managed device 104 at the same time using the visual indicators 118 in connection with multiple work orders 136.
Each of the multiple visual indications is provided in a different way from the other visual indications that are provided at the same time (for example, by having the associated LED 118 be illuminated using a different color, a different blinking rate, and/or different blinking pattern). Each visual indication is provided in connection with a different work order 136.
A technician that is performing a given work order 136 uses the mobile application 140 executing on a smartphone 138 to help the technician perform the work order 136. The mobile application 140 and the management system 112 are configured so that when a visual indication is provided at the managed device 104, the mobile application 140 displays on the smartphone 138 what that particular visual indication looks like (for example, by displaying on the smartphone 138 an image 141 that shows the color, blink rate, and blink pattern that is used to provide that visual indication). In this way, the technician is able to determine which visual indication is associated with the work order 136 that the technician is performing at that time. As a result, multiple technicians are able to work on multiple active work orders 136 at the same time at a given managed device 104, with multiple visual indications being provided simultaneously at the managed device 104.
FIG. 2 is a flow diagram of one exemplary embodiment of a method 200 of providing multiple visual indications at a managed device simultaneously in connection with multiple active work orders. The exemplary embodiment of method 200 shown in FIG. 2 is described here as being implemented using the system 100 shown in FIG. 1, though it is to be understood that other embodiments can be implemented in other ways. Moreover, the blocks of the flow diagram shown in FIG. 2 have been arranged for ease of explanation; however, it is to be understood that this arrangement is merely exemplary, and it should be recognized that the processing associated with method 200 (and the blocks shown in FIG. 2) can occur in any order (for example, using standard event-driven programming techniques).
Moreover, as noted above the example shown in FIGS. 1 and 2 is described as involving two active work orders 136 and two portable devices 138; however, it is to be understood that this is merely exemplary, and that different numbers of multiple active work orders and portable devices 138 can be used.
Method 200 comprises providing a first visual indication 117 (shown in FIG. 1) at the managed device 104 in connection with a first work order 136 (block 202) and providing a second visual indication 119 (shown in FIG. 1) at the managed device 104 in connection with a second work order (block 204).
The first work order involves a first connection using the managed device 104 (for example, involving a first service port 116 of the managed device 104), and the second work order involves a second connection using the managed device 104 (for example, involving a second service port 116 of the managed device 104).
The first visual indication 117 and the second visual indication 119 are provided simultaneously for at least a part of the time the first visual indication 117 is provided and for at least a part of the time the second visual indication 119 is provided.
Each of the first and second electronic work orders 136, in this example, is communicated to the mobile application 140 executing on the respective smartphone 138 used by the technician that is assigned to perform that electronic work order 136. Each electronic work order 136 can be wirelessly communicated from the electronic work order application 134 to the respective smartphone 138 (for example, using a cellular or wireless local area network communication link) or using a wired connection to the Internet, a local area network, or a direct connection between the smartphone 138 and the computer 124 on which the electronic work order application 134 executes.
After each of the first and second electronic work orders 136 has been downloaded to the mobile application 140 on the respective smartphone 138, the relevant technician can use the mobile application 140 to view the electronic work order 136 and the steps included in the electronic work order 136. After the technicians have travelled to the location where the managed device 104 is installed, the technicians can use the mobile application 140 executing on the smartphones 138 to assist the technicians in carrying out the steps in the work orders 136.
In this example, the management system 112 controls the providing of the first and second visual indications 117 and 119. To provide the first visual indication 117 at the managed device 104, the management system 112 sends a message to the controller 110 in the managed device 104 indicating that the relevant LED 118 in the managed device 104 associated with the relevant step of the first work order (for example, an LED 118 associated with a service port 116 affected by that step) should be illuminated in a particular manner (for example, should be illuminated using a particular color, blink rate, and/or blink pattern). Likewise, to provide the second visual indication 119 at the managed device 104, the management system 112 sends a message to the controller 110 in the managed device 104 indicating that the relevant LED 118 in the managed device 104 associated with the relevant step of the second work order (for example, an LED 118 associated with a service port 116 affected by that step) should be illuminated in a particular manner (for example, should be illuminated using a particular color, blink rate, and/or blink pattern).
In this example, the first visual indication 117 differs from the second visual indication 119.
The method 200 further comprises displaying what the first visual indication 117 looks like on a first portable device 138 configured to display information about the first work order 136 (block 206) and displaying what the second visual indication 119 looks like on a second portable device 138 configured to display information about the second work order 136 (block 208).
As noted above, in this example, the first and second portable devices 138 are implemented using first and second smartphones 138 (though the portable devices 138 can be implemented in other ways).
In this example, the management system 112 is communicatively coupled to the first and second smartphones 138 and is configured to control the displaying of information about the first work order 136 on the first smartphone 138 and the displaying of information about the second work order 136 on the second smartphone 138 by sending appropriate messages to the smartphones 138 (and the mobile applications 140 executing thereon).
In this example, the mobile application 140 executing on the first smartphone 138 displays on the first smartphone 138 what the first visual indication 117 looks like (for example, by displaying on that smartphone 138 an image that shows the color, blink rate, and blink pattern that is used to provide the first visual indication 117). Likewise, in this example, the mobile application 140 executing on the second smartphone 138 displays on the second smartphone 138 what the second visual indication 119 looks like (for example, by displaying on that smartphone 138 an image 142 that shows the color, blink rate, and blink pattern that is used to provide the second visual indication 119). One example how this done is shown in FIG. 1.
In this way, each technician is able to determine which visual indication is associated with the particular work order 136 that the technician is performing at that time. As a result, multiple technicians are able to work on multiple active work orders 136 at the same time at a given managed device 104, with multiple visual indications being provided simultaneously at the managed device 104.
A number of embodiments have been described. Nevertheless, it will be understood that various modifications to the described embodiments may be made without departing from the spirit and scope of the claimed invention.
