ABSTRACT:
Pin fraud of battery reversal pulse metered sophisticated coin telephones is detected, an announcement of the detected fraud made, and the fraud is stopped if the detected fraud continues by the method and apparatus of the invention. By carefully monitoring within the switch office the loop current that is flowing in the 48 volt battery circuit, especially in the more positive terminal portion of the 48 volt battery circuit, loss of current to a fraud ground at a remote coin telephone can be detected. Once a fraud ground is detected, an announcement is made to at least the calling station where the pin fraud was detected, which says in effect "The pay telephone you are using is charging improperly for the service provided. If such improper charging continues the present call will be discontinued." A convenient location in the switch office and an inexpensive component configuration make the addition of this pin fraud detection, announcement and prevention apparatus very cost effective.
