Abstract: A method for signal gain adjustment in a multi-port, digital distributed antenna system uses a sorter to sort received signals in ascending order according to their signal levels. A threshold comparator generates a dynamic range fair threshold that is updated as any remaining system dynamic range is distributed amongst the remaining signals. Any received signal that is less than or equal to the threshold is attenuated with a unity gain factor. A signal that is greater than the threshold is attenuated with a gain factor that is inversely proportional to the signal level.

Abstract: The present invention relates to a telecommunications termination panel with a housing including a front opening and a rear opening. Pivotably mounted within the housing is a tray within the front opening, pivoting about a vertical axis located adjacent a first side of the housing.

A movable plate is positioned adjacent the first side and is movable between a first position defining an upper limit of the cable path when the tray is closed and a second position allowing access to the cable path when the tray is open. The movement of the plate between the first and second positions is actuated by the movement of the tray between the closed and open positions. The present invention further relates to a telecommunications termination panel with a housing including a front opening.
