ABSTRACT:
A detachably attachable protection device for use with a circuit routed to a DSX panel or the like in a telephone switching station includes a fixed plate having apertures for visual access to a light associated with the circuit, an aperture for access to a monitor jack and a pivotable plate connected to the fixed plate for selectively providing access to jacks for rerouting the circuit. The lift tab may be incorporated to assist in positioning the pivotable plate. In a variant protection device, a plurality of pivotable plates secured to a common fixed plate may be employed to individually protect all circuits routed to a DSX panel.
