A ringing signal operates bells or other ringtone generators in a telephone, to alert the user there is an incoming telephone call.
In landline telephones, bells or ringtones were rung by impressing a 60 to 105-volt RMS 20-Hertz sine wave across the tip and the ring conductors of the subscriber line, in series with the (typically) -48VDC loop supplies. This signal was produced by a ringing generator at the central office. Many 20th-century multi-party lines used ring frequencies other than 20 Hz for selective ringing of some parties.
Once the subscriber line was called, a relay on the subscriber line card connects the ringing generator to the subscriber line. The exchanges also send a ringback tone to the calling party. When the called party answers by taking the telephone handset off the switchhook, the subscriber's telephone drawd direct current from central office battery. That current was sensed by the line cards and the ringing relay was de-energized.
