ABSTRACT:
A connector block for interfacing incoming telephone lines to telephone central office switching equipment includes a generally rectangular elongated mounting panel having a plurality of sockets arranged in groups in horizontal rows and vertical columns across a major portion of the width of the panel. Each of the socket groups mounts a generally rectangular plug-in protector assembly in such a manner that the long side of the protector assembly is generally parallel to the horizontal rows of socket groups. Adjacent to and associated with each two rows of the socket groups is a group of cross-connect pin terminal holes. Integrally formed with the edge of the mounting panel adjacent the groups of cross-connect pin terminal holes is a fanning strip having a flange portion transversely extending from the panel through which flange portion extends a plurality of openings to permit access between the front and back of the panel.
