An internal support plate is inserted on the backing plate of a coinless telephone station to reinforce a projection on the backing plate without any field modification of the station. The internal support plate has a projection which is sized and configured to mate with and thereby reinforce the projection on the backing plate.

An adapter permits a telephone repair technician to attach his data communications equipment to a C-set or D-set pay telephone station without alligator clips by a direct connection with the RJ11 connectors of a data terminal or the like. The adapter can be in the form of a housing having different corner radii and two jacks, one of which is wired in the C-set mode and the other of which is wired in the D-set mode, or one jack and a switch for achieving the C- and D-set modes. The adapter has pins arranged to plug into a standard 11-pin connector in the telephone station lower housing.

A pay telephone station having a lower housing coin chute (14) which is provided with a coin fraud prevention unit (10) in the form of a thin base (15) arranged in a slot (11) of a coin channel cover plate (12). The base (15) is provided with a pawl (23) having a tooth (24) with a chamfered face ( b 25) which is biased into the path of a coin passing through a coin path (39) by a torsion spring (26). An anchor (59) for connecting a handset (56) to the upper housing coin dial unit (50) of the station includes a base with apertures (63, 64) and a V-shaped body (65) with a notch 66 defined between surfaces (69, 70). A long thumbscrew member (74) with a textured gripping surface connects the anchor (59) to a projector (51) integral with the upper housing (50). The handset cord assembly (A) is first passed through an aperture (54) in the projection (51) and then through the aperture (64) in the base (60). A button (68) firmly attached to a lanyard (67) in the armor (55) of the assembly (A) is held against the surfaces (68, 70) by the lanyard (67) and in the notch (66) by the thumbscrew (74) adjacent the button (68). A shorting connector (80) is provided for rapidly changing hook switch configurations in the upper housing coin dial unit (50). A configuration module (90) is used to rapidly and easily connect various circuits (93, 94, 95, 96, 97, 98, 99) on a printed circuit board (92) in the upper housing coin dial unit (50).
