How does an old telephone ringer work?
In landline telephones, bells or ringtones are rung by impressing a 60 to 105-volt RMS 20-Hertz sine wave across the tip and ring conductors of the subscriber line, in series with the (typically) −48 VDC loop supply. This signal is produced by a ringing generator at the central office.

What voltage is a telephone ringer?
The most common frequency used to ring telephones is 20Hz, while 16Hz and 24Hz are also widely used. The output voltage is about 90V with less than 10mA-per-bell output current capability.
What is ring generator?
Ring generators are high-performance linear feedback shift registers capable of handling pseudorandom and deterministic binary sequences. They outperform all traditional solutions by providing an unprecedented speed of operations and a layout-friendly structure.

The red and green wires are on the two center terminals of a normal phone jack, and the black and yellow wires are on the two outer terminals. This arrangement allows most normal houses to handle two phone lines very easily.
Is ringing voltage AC or DC?
Alternating Current
AC (Alternating Current), which is used for ringing, means the voltage goes positive, to zero, and then negative by the same amount over a given period of time (for a phone line ringing at 20 cycles, there are 20 complete cycles per second).
What voltage is a phone line?
The phone company sends this power directly to your house through a pair of dedicated wires that connect to your phone jack. When the phone is not in use, this is a constant DC signal (about 50-60 volts). When the phone rings, the signal is a 20 hertz AC signal (about 90 volts).
Is telephone line voltage AC or DC?
DC
These two wires provide: DC current to power the telephone electronics, AC current to ring the telephone bell or electronic ringer, full duplex balanced voice path. This is a closed loop, balanced system not referenced to earth ground. The POTS phone line, with all phones on-hook, should measure around 48 volts DC.
How can I make my landline ring itself?
Call your phone company and request the ring back number for your phone. Most phone companies, in different areas, have a 2 or 3 digit code they can give you to use to make your own phone ring. Follow the directions of your phone company for using the ring back number.
