Pulse dialling and DTMF what is the difference?
All of our vintage rotary dial telephones and some (but not all) of our push button telephones are Decadic or Pulse-dialling .
This means that the decadic phones can dial out fine, and make calls. However what they cannot do is interact with voicemail which requires a DTMF or VF tone dial phone to do. It also means if you need to "press 3 for a representative" when you are calling a call centre or doing your telephone banking, a decadic phone will not work, you need a DTMF phone.
Pulse dialing, dial pulse, or loop disconnect dialing, also called rotary or decadic dialling in Australia (because up to 10 pulses are sent), is pulsing in which a direct-current pulse train is produced by interrupting a steady signal according to a fixed or formatted code for each digit and at a standard pulse repetition rate.
Dial pulsing originated with a rotary dial integrated into telephone instruments, for the purpose of signaling. Subsequent applications use electromechanical or electronic circuits to generate dial pulses.
The pulses are generated through the making and breaking of the telephone connection (smilar to flicking a light switch on and off); the audible clicks are a side effect of this. As a result, all that is really needed to dial a number with pulse dialing is a switch. Each digit in the number is represented by a different number of rapid clicks. In most countries one click is used for the digit 1, two clicks for 2, and so on, with ten clicks for the digit 0; this makes the code unary, excepting the digit 0.
Individual digits in a phone number need to be separated with a short pause so as not to merge into each other (originally, to give the uniselector rotary relays at the exchange time to rotate). In rotary systems this interdigit interval is provided by the slow rotation of the mechanical dial.
Most fixed-line phones now use dual tone multi frequency (DTMF, also called touch tone or tone dialing), supported by push-button telephones, rather than pulse dialing, but most telephone equipment retains support for pulse dialing for backward compatibility.
