You won't believe these 10 facts about people. A dial tone is the signal that a person hears on a landline telephone before he dials a phone number. In most instances, the signal disappears once the first number is dialed. In most cases, cell phones do not have a dial tone.
When you press the buttons on the keypad, a connection is made that generates two tones at the same time. A Row tone and a Column tone. These two tones identify the key you pressed to any equipment you are controlling. If the keypad is on your phone, the telephone company's Central Office equipment knows what numbers you are dialing by these tones, and will switch your call accordingly.
