I think different tones na ang each number na being dialed. Pwede man kuno mo gamit ka ug musical keyboard then mag press ka sa sakto na keys sa keyboard then ipa dungug nimo sa mic sa telephone then maka dial ka.

if i remember correctly, in a touch tone telephone, when you push a certain number on the keypad, it produces a certain frequency which is a combination 2 different frequencies.

Analog or Digital? Pulse or Tone?

[vas_o]

I think analog to digital (binary) then back to analog.

dtmf for touch tone, pulse for rotary (katong karaan kaau nga phone). puros mani sila analog, please correct me if i'm wrong.

ariap, why are you concerned about this?
