  • System for direct suppressed ringing access of subscriber lines
    Patent number: 6275571
    Abstract: The system for direct suppressed ringing access of a subscriber line enables the service provider to access subscriber lines from any location, as long as the incoming call is identified and authenticated as a suppressed ringing access call. The central office switch can maintain a list of predefined line numbers that are used by an authorized service provider to perform the suppressed ringing access function. Thus, a call origination on one of these lines is automatically validated as a suppressed ringing connection call. Alternatively, the suppressed ringing connection is requested by the inclusion of a predefined code in the dial string and the central office switch automatically authenticates the identity of the service provider.
