Abstract
Abstract Adaptor brackets are arranged for use with conventional telephone equipment connector blocks having cross-connect fields normally presented to the technician in a predetermined plane. Through use of the brackets the plane of the cross-connect fields may be temporarily rotated from the predetermined plane thereby facilitating access to the cross-connect field terminal strips during a double blocking technique used at a distributing frame of a telephone central office in preparation for subsequent cut-over of new switching system equipment.
