Abstract
An access device is provided for a main distribution frame of a telephone system. The access device, which may be structured as a set of access blocks, is positioned between surge protection modules and their corresponding vertical input terminal block so as to make electrical contact with the subscriber telephone line without interruption of the array of harnesses which couple together the various terminal blocks of the main distribution frame. A printed circuit contained within each of the access blocks comprises conductors which contact feed-through terminals of the access block, the conductor coupling these terminals to multiplexers which provide for the selective coupling of messages from the subscriber lines to the subscriber line of a message receiving station.
