A series of individual telephone subscriber circuit modules for use with telephone connector blocks having flat insulation displacement clips projecting from a planar surface thereof. The block mounts a grounding strip medially positioned on said surface. The modules employ known protection components, and in various modifications, are suitable for providing alternatively three point protection or five point protection utilizing either or both of gas tube and fuse components.
