1. Apparatus for prepayment of telecommunication connections between first and second telecommunication devices, each said telecommunication device being operably associatable with telecommunication lines of a telecommunication switching network having a billing system utilizing rates and the duration of telecommunication connections to compute the cost of telecommunication connections in said telecommunication switching network, said apparatus being operably associatable with said first telecommunication device and comprises:

  • data storage means for storing telecommunication-time data representative of a prepurchased amount of telecommunication time available for prepayment of telecommunication connections in said telecommunication switching network;

    insertion means for insertion along the telecommunication line between said first telecommunication device and said telecommunication switching network, and permitting a dialing signal generated from said first communication device to be transmitted to said telecommunication switching network and initiate a telecommunication connection between said first and second telecommunication devices;

    time measuring means for measuring the time duration of said telecommunication connection between said first and second telecommunication devices;

    data processing means for processing said stored telecommunication-time data so as to indicate at least one decrement in said prepurchased amount of telecommunication-time, said at least one decrement being essentially equal to the measured time duration of said telecommunication connection; and

    disabling signal generation means for generating a rate-disabling signal so as to disable the utilization of rates in said billing system for computing the cost of said telecommunication connection.
