Abstract: A conventional telephone pay station is adapted for coin-free restricted dialing of a preselected number of digits by employing a two-coil latching relay operating a switch for shunting outgoing calls, one coil being operated after a predetermined time delay responsive to detection of an offhook condition to open the switch, and the second coil being operated responsive to the detection of dialing by the calling party of a number of digits greater than the preselected number to close the switch. Anti-fraud circuits are provided to interrupt tone generator operation after a predesignated time delay following each digit, and to interrupt service after each hook switch operation.
