Abstract
Abstract A repeater case for high-density subscriber lines includes a repeater base and repeater case housing formed of a fiberglass composite and together forming a sealed enclosure for a pressurized atmosphere. The repeater case housing has a removable cover secured in position by torque bolts, a sealing gasket to sealingly receive the cover, a plurality of high-density subscriber line module slots and a plurality of printed circuit boards mounted to certain of the slots with gaps between adjacent printed circuit boards, the printed circuit boards being adapted to receive respective high-density subscriber line modules. The repeater base has a cable inlet, and each of the plurality of printed circuit boards is provided with a connection to the cable inlet and a connector to electrically receive one of the high-density subscriber line modules. The repeater base also includes an electrically insulating barrier between the cable inlet and the printed circuit boards. A plurality of openings in the barrier permit cooling atmosphere to pass from the repeater base toward the modules so that cooling atmosphere may pass over the high-density subscriber line modules through the barrier and the gaps between the printed circuit boards.
