A zone cabling termination cabinet of fire-resistant metal, provides a non-plenum enclosed space, close to the work station it serves, recessed into the plenum above a suspended ceiling, for housing communications cable connections and switching, without the need to use high-cost plenum fire-rated materials. The cabinet has an equipment mounting plate removably mounted on the interior surface of an access door, which when closed is flush with the bottom wall of the cabinet, which in turn is flush with the suspended false ceiling. The exposed lower surface of the door is clad with fire resistant ceiling tile material, the utility thereof being two-fold: the cladding makes the cabinet more fire resistant, and visually it blends with the rest of the ceiling, is inconspicuous and not readily detected by the unsuspecting eye, thus providing some measure of security from unauthorized meddling. The equipment mounting plate is easily removed from the door for making necessary cabling and switching changes at a remote workbench or table top. Cables enter and exit the cabinet through fire-rated penetrations in opposing side walls of the cabinet. The cabinet facilitates the decentralization of cable terminations and switching for location in secure user-defined zones of a building close to the work stations served thereby, thus eliminating the need for large, centralized and insecure IDFs.
