  • Patent number: 5737400
    Abstract: A no-ring access telecommunications system is connected to a subscriber's telephone line at the demarcation point between the public switched telephone network and the telephone line or at the utility meter site on the subscriber's premises, or at a central office. The telecommunications system comprises a processor, and a normally open switch which is selectively closed by the processor to connect the telephone line to another line servicing subscriber telecommunications equipment connected in parallel thereto. The telecommunications system is programmable to suppress the first power ring signal of an incoming call on the telephone line from a remote host system. The ring signal is analyzed for Caller ID, distinctive ringing or other special tone. If a valid Caller ID, distinctive ring signal or other special tone is provided, the switch is closed. The Caller ID is regenerated on the line servicing the subscriber telecommunications equipment.
