Abstract: An integral multiple transmission line interface comprises a panel having opposite side portions defining, facility connection and subscriber connection regions having, respectively, a facility cable connector and subscriber cable terminals. A plurality of spaced modular jacks are arrayed longitudinally along the facility connection region of the panel, and a plurality of removably attached subscriber wiring bridges extend between the jacks and subscriber cable terminals. Interconnection between the subscriber wiring bridges and the facility cable connector is made through a printed circuit board within the panel. A pivotally mounted, removable cover protects the subscriber wiring terminals from human contact, and interlocking ears and collars formed on the panel enable the terminal devices to be stacked end to end.
