Abstract

An improved terminal connecting block and bracket assembly is disclosed. The terminal connecting block contains four sets of flat elongate electrically conductive elements. Each of the third set and each of the fourth set of elements is electrically isolated from the other sets of elements, and a unitary connector connects the sets of elements to auxiliary devices and central office equipment. Removable bridge connectors provide different interconnections without rewiring. The terminal connecting block is used with a bracket for mounting the block on a surface.
