Abstract
Abstract A connector for a main distributing frame comprises two spaced apart panels with the first panel having pluggable electrical protector sockets and test points mounted therein flush with the outside face. The test points and the outside plant ones of the protector sockets have pin terminals extending therefrom into the space between the two panels. The central office ones of the protector sockets have pin terminals extending therefrom through the second panel to present wire wrappable ends at the outside of the second panel. Connections of outside plant conductors to the test point terminals and connections from these terminals to the protector sockets are protected in the space between the panels. If desired, the test point terminals can be prewired to cable-connectors mounted on the first panel which are adapted to receive mating connectorized outside plant stub cables. A slideable cover mounts over the wire wrappable ends at the outside of the second panel to provide protection thereto. The connector mounts in bookcase fashion within the main frame.
