Abstract: A communications connector tester for quickly and accurately analyzing communications connectors at production to determine whether the connectors are fit for use in certain communications applications is disclosed. Test signals at several discrete frequencies are sequentially inputted into pairs of conductors in the communications connector under test, and output signals are detected for the pairs under test. The output signals are compared to acceptable ranges for certain applications of the communications connector and the connector is passed or failed for certain applications based on the output signal values. Near-end crosstalk, far-end crosstalk, return loss, insertion loss, and other communications connector qualities may be measured using the present invention.

Abstract: A building control system is provided that receives information from devices of different subsystems. A trigger causes a zone controller to store the information in a database. The stored data is used to generate customized reports based on sequences or sets of related events. The information from multiple subsystems is consolidated, analyzed, and patterns of behavior are determined. The trigger also causes execution of control actions throughout the building spanning the multiple subsystems, devices, and areas based on the information. An access control subsystem and a non-access control subsystem of the building control system are linked using a common network such that a change in the state of an access control device can affect the state of a non-access control device and a change in the state of a non-access control device can affect the state of an access control device.

Abstract: A one-piece cable tie, such as an in-line cable tie, includes a hybrid locking mechanism including both a fixed locking wedge and a hinged locking wedge. The hinged locking wedge may be laterally offset from the fixed locking wedge along a longitudinal axis of an internal passageway of the cable tie head. Preferably, the hinged locking wedge is located on a top surface of the passageway while the fixed locking wedge is located on a bottom surface of the passageway. The hinged locking wedge may be located close to the strap ingress. The cable tie is preferably made of Nylon 6.6, yet can achieve both a low thread insertion force and a high loop tensile strength suitable for demanding applications. Maximized strength is achieved through use of multiple teeth on each of the hinged and fixed locking wedges.

Abstract: Systems and methods for decreasing alien crosstalk use enhanced patch cords for introducing additional attenuation. The enhanced patch cords are preferably shielded to reduce alien crosstalk down their lengths and also attenuate signals passing therethrough to a greater extent than standard communication patch cords. The interaction of two enhanced patch cords results in two suppression steps for alien crosstalk and only one suppression step for intended signal passing through a communication cable.

Abstract: A method for reducing crosstalk between a plurality of wires in a network cable using a network cable jack that includes a printed circuit board (PCB) for balancing both inductive and capacitive coupling. The method includes using two distinct inductance zones separated by a neutral zone. Significant gains in degrees of freedom are achieved for designing PCB trace patterns in which a pair of inductive coupling zones jointly offset the inductive coupling caused by a specification plug and the jack contacts, both in magnitude and phase angle. Further, using distinct inductance zones offers more freedom regarding the placement of capacitive plates for use in capacitance balancing as well as the placement of terminals and insulation displacement contacts. Although the magnitude of a capacitive coupling is determined by the length of the capacitor plates parallel to current carrying traces, the approach allows capacitive and inductive coupling to be balanced independently.

Abstract: A block-out cover is installed in a jack module to prevent entry of undesirable objects. The block-out cover includes at least one window and at least one locking arm.

The removal tool includes a body, a lever secured to the body to engage the cover and a prong with a cam surface. The cam surface of the prong deflects the cover from locking engagement with the jack module allowing the removal tool to remove the block-out cover.

Abstract: A method and apparatus are provided for monitoring and reporting cable connectivity such as patch panel port-level connectivity on a real-time basis. For patch panel systems, the approach is based upon a distributed architecture that may be modularly scalable and may reduce, if not eliminate, the need for a centralized signal processor and complex cabling between patch panels and the centralized signal processor. Each patch panel may determine port level connectivity independently. Polling delays and polling-related overhead processing may be reduced or eliminated by supporting real-time monitoring of port connectivity at the port level. The approach provides improved real-time reporting of patch panel connectivity with reduced cabling complexity, increased reliability, and decreased maintenance costs. In addition, the approach is compatible with (i.e., may communicate with and be controlled by) a multipurpose network management system (NMS). In addition, a compatible revision system is provided.
