Abstract

A base-plate for a telephone set base has a bottom web or panel, with a wall extending upward around the panel for the majority of its periphery. At one side an inclined web extends inward and upward and a wall extends round the periphery of the web, with an aperture formed in the bottom panel coincident with the inclined web. The inclined web, and the wall around the web define a lower recess and an upper recess. A further recess in the bottom panel, closed on three sides and top and open on the fourth side provides access for modular plugs of the handset cord and line cord. Enclosed channels extend from the upper end and lower end to the further channel for passage of line and handset cords. A further enclosed channel extends from the lower recess to the channel from the upper end for alternate positioning of a short line cord in a wall mounting mode. Mounting means for a circuit board, hook switch and piezoceramic transducer are provided.
