Abstract: A network cabinet is provided comprising a door comprising first and second opposing lateral sides. A hinge lever is rotatably connected to the door and a retractable hinge pin is connected to the hinge lever and is positioned closer to the first lateral side of the door than the second lateral side. A lever stop is also connected to the door and is associated with the hinge lever. The lever stop prevents retraction of the hinge pin from an extended position with the second lateral side of the door in an open position.

Abstract: A network cabinet is provided comprising a support frame and a threshold associated with the support frame. A door comprising first and second lateral sides is mounted to the support frame through a hinge pin. The hinge pin is moveable between retracted and extended positions and is positioned closer to the first lateral side of the door than the second lateral side. A bearing surface is also associated with the support frame and is aligned with the hinge pin such that the door is elevated relative to the threshold with the hinge pin in the extended position and in contact with the bearing surface.

Abstract: A method and apparatus for energizing a multi-channel LNBF containing multiple LNB(s) the LNBF connected to multiple IRDs. The number of IRDs present is detected. If more than one IRD is present, all LNBs are energized. If only one IRD is detected, power sufficient to supply the LNB the IRD has selected is supplied. Identification of which LNB the single IRD has selected may be determined by monitoring the presence of a desired voltage, frequency tone, and or series of frequency tones.

Abstract: An apparatus, method and computer program for initiating and maintaining a virtual connection between a mobile radio and a ground station, including receiving a plurality of ground station radio signals from a mobile radio; accumulating over a time period signal quality information relative to each of the ground station radio signals; determining a signal quality parameter trend for each of the ground station radio signals as a function of the accumulated signal quality information; deciding to switch a current virtual connection between the mobile radio and a first ground station to a virtual connection between the mobile radio and a different second ground station as a function of comparing the signal quality parameter to a pre-selected minimum acceptable threshold signal quality parameter; and switching the virtual connection of the mobile radio from the first ground station to the second ground station.
