ABSTRACT:
A set of testing tools for modular telephone systems of the type which employ a telephone having a base, a terminal block, a line cord interconnecting the base and terminal block, a handset, and a receiver cord interconnecting the handset and base. The connections between the line cord, receiver cord, base and terminal block are effected by known miniature jacks and plugs. The present invention provides a testing tool equipped with substantially identical miniature jacks and/or plugs and permits the house cable to be identified and the presence of dial tone, ground and battery to be checked without requiring the terminal block to be removed from the wall. The testing tools also permit trouble to be localized in standard desk, wall, Princess.RTM. and Trimline.RTM. telephone sets without having to dismantle same.
