The control panel seizes the phone line and dials the Customer Care Center (CCC).2. The control panel waits to hear a “handshake” frequency tone from the receiver to confirm that thereceiver is on-line and ready to receive its message.3. After the panel hears the correct handshake, it transmits its message.4. If the message is received and understood by the receiver, it transmits a “kissoff” frequency tone.
