ABSTRACT:
An interface for modems is described which provides rapid identification of a caller and limited access based on a variety of parameters obtained from caller identification information encoded by the telephone company. The incoming telephone call information is compared to a preprogrammed access matrix to determine if the caller is authorized to access the modem connected to the interface. A telephone call screening method and apparatus which incorporates the encoded caller identification is also described. Finally, a method and apparatus for a telephone database for statistical accounting is described.
