ABSTRACT:
A telephone network interface device adapted to be connected to and in between a telephone subscriber premise wiring and a Telephone Company owned subscriber loop comprising a backwall and a sidewall affixed to the sidewall delimiting a cavity in which there is: first and second sets of terminals connected to the backwall and a device to place the terminals of the first set in removably electrical communication with the second set of terminals, the first set of terminals comprising first and second spaced-apart dielectric blocks, each dielectric block containing a plurality of terminals and a plurality of first slots in a first surface and a second slot in a second surface, each of the first slots in the first dielectric block being in alignment with one of the first slots in the second dielectric block and disposed essentially perpendicular to the base and the second slots are mechanically and slideably fitted over a rib on the base so that the dielectric blocks may be slideably moved towards and away from one another. Affixed to the sidewall are outer and inner overlapping removable doors, both hingeably engaged to the sidewall and adapted to be rotated between a closed and open position. A hinge rotatively engages the outer and inner doors to the sidewall, prohibiting disengagement of either door when the inner door is in the closed position and permitting disengagement of the outer door when the inner door has been placed in a predetermined position.
