A caller-identification receiving apparatus can process the data message of a caller-identification without a micro-controller by utilizing a ring signal to activate circuits in a sleeping state while the telephone is on-hook. Moreover, the device has a timer to automatically activate the circuits in the sleeping state to detect the signal of a channel seizure and process the message-waiting.
