ABSTRACT:
Apparatuses and methods immediately alert a telephone company or other owner/host or operator of a payphone that a vandalizing stuffing has occurred, thereby enabling it or him or her promptly to dispatch a maintenance person to the particular payphone or station to fix it. Stuffing sensing switches are advantageously mounted in a coin return mechanism, and in electromechanical payphones electrically connected to the telephone company central office over one of the existing RING and TIP wires connecting the stuffed or compromised payphone with the central office. Conventional testing techniques periodically employed in the office by the telephone company over the existing wit. installation will then sense whether a payphone has been compromised or stuffed. In electronic payphones, a payphone computer monitors the sensing switches and calls the owner/host or operator to report a problem or gives a local alarm.
