Abstract: A communication system detects special service information (e.g., calling party identification) during a silent interval between ringing signals on an incoming call and stores the information in a call record created for the call. In response to predetermined call conditions, this information is included as part of a control signal sent over an extension loop to a station terminal. Call features such as delayed ringing, hold, call transfers, line preselect and switch hook status are utilized to control where, when and if this information should be displayed at various station terminals.
