Patent US2. 00. 50. Powered patch panel.
CROSS- REFERENCE TO RELATED APPLICATIONS . Provisional Application Ser. LCB4. 64, entitled . BACKGROUND OF THE INVENTION . Issues with documenting and managing LANs have likewise increased the need for timely response when connectivity problems arise. This is even more important with the advent of voice over internet protocol (Vo. IP) replacing the function of the traditional phone network, but now operating over the same LAN as data services.
Local area networks are subsuming more and more of the responsibility for carrying the total electronic communication capability of a business or home. Traditionally, telephone networks and data networks have been maintained as two separate networks with their own wiring requirements and peculiarities.
This has largely been due to the regulatory requirements on telephone service to supply life line capability and electrical issues such as a relatively high DC ring- tone voltage. However, the cable types and characteristics have remained distinct. This is true for large offices, residential and Small Office- Home Office (SOHO) and Multi- Dwelling Units (MDU) installations. SUMMARY OF THE INVENTION .
According to some embodiments of the present invention, the active jack can be located at the wall in an enterprise office, in a patch panel within the cable distribution plant, in a user device or in two or more of these areas. According to some embodiments of the invention, the active jack includes at least two 1. Mb/s Ethernet ports and is a network element (NE) on the local area network (LAN).
One Ethernet port of the active jack is the network port and connects to the horizontal wiring of the LAN system. At least one other port is the user port into which Ethernet capable devices, such as a personal computer (PC) or a Voice over IP (Vo.
IP) telephone, plugs into in order to gain access to the LAN. The active jack may act as a two port Ethernet switch routing data between the two ports. Since the active jack has a MAC address it responds to Address Resolution Protocol (ARP) requests from the network and transmits ARP messages when powered up or queried to indicate presence on the network. The ARP message and the associated physical location information of the active jack can be used to provide information regarding the connectivity of the structured cable system, i. LAN cable plant. Such sources are deployed in networks as the source of DC power for an attached powered device (PD) such as a Vo. IP telephone that receives power according to a power- over- network scheme. According to some embodiments of the present invention, the power consumption of the active jack is minimal, with the remaining power forwarded to a powered device (PD) if one is connected.
According to one embodiment of the present invention, PSE equipment such as an Ethernet switch or IP router is used. According to another embodiment a patch panel or mid- span patch panel can be used. When a patch panel is equipped with active jacks, a managed structure cable PSE system is obtained. The scope of management that a patch panel has can be enhanced if an active jack is used between the patch panel and the end device.
Further, if changes occur it is required that they are well documented and manually entered in the security/management system database. According to one embodiment of the present invention, use of active jacks facilitates monitoring the state of the patch cords and the horizontal cable system to provide a managed, structured cable system. If there is a removal or movement of a particular cable, the active jacks connected by the cable will lose upstream network connection. An active jack in a patch panel can detect the change periodically, for example, via once- per- second .

Because the PSE and PD communicate, the PSE can instantaneously report opens in the patch cord. Optionally, an active jack can send a message to a neighboring active jack to report communication problems. When the connection is re- attached, the active jack may send out an ARP message to indicate that it is back on line with any other devices connected to it. As the connection is re- established the switch port to the patch panel port is thus identified, an important aspect to managing the patch cord connectivity. Since the physical location information can be associated with active jacks, even momentary changes to the cable plant may be recognized and logged.

The active jack provides for remote monitoring, obviating or reducing the need to send out a technician to determine the state of the equipment. Service, can be remotely suspended or re- instated. Furthermore, end point devices which connect to a network using active jacks can be inventoried and controlled as well.
The active wall jacks can offer power over Ethernet (to power the phone) and/or provide a physical location address to support E9. The internal switches will continue to direct and manage Vo. IP calls to the outside world but deny other IP data transactions. According to one embodiment of the present invention, an advantage of the power patch panel with the active jack is that it can allow the upstream switches to power down during an AC power outage. The traffic can then be directed to a . Power may be provided under the IEEE 8. BRIEF DESCRIPTION OF THE DRAWINGS .
