1. Telephone call handling apparatus for use in combination with a plurality of telephone lines and a plurality of groups of call answering stations, and comprising:

  • detection means for detecting from said lines dialing signals defining a called number identifying one of said groups of call answering stations;

    clock means for generating time signals defining present time;

    means for recording the identity of a line from which dialing signals defining a called number are detected by said detection means and for recording time signals generated by said clock means and representing time of request for said called number;

    circuit means for comparing said recorded time signal with current time signals generated by said clock means, and for generating difference signals defining a time difference between said recorded time signals and said current time signals;

    means for generating time trigger signals defining numerical constants representing first and second time triggers;

    means for comparing said difference signals and said time trigger signals for generating a first output signal when the numerical value represented by said difference signals exceeds the numerical value of said first time trigger and for generating a second output signal when the numerical value represented by said difference signals is less than the numerical value of said second time trigger;

    means responsive to said first output signal generated with respect to time of request for a first called number and said second output signal generated with respect to time of request for a second called number to connect a line from which dialing signals defining said first called number are detected to a call answering station of the group of call answering stations identified by said second called number.
