Hi, friend!

Pulse dialing indicates the digit in the phone number by series of clicks, which corresponds only to that particular digit. It would then actually need a short pause so as to clearly identify a particular digit from the next one or the other one. While Tone dialing, on the other hand, is also referred to as Dual Tone Multi-Frequency, which uses different tones to indicate a different number.

Instead of sending different or multiple signals for each of the digits, it would need to send only one for each. In most cases, the most discriminating part between sets of phones which use pulse or tone dialing is the mechanism they use to dial the number. Tone dialing handsets use a numeric keypad where each digit could actually be pushed. Although there are some versions of pulse dialing phones with numeric keypads, the most prevalent models were those with rotary dials.

Have a nice day!

Hi!

'Tone/pulse' is a selection between touch tone dialing and pulse dialing.

Almost all telephone networks in today’s world use tone dialing. It is the method of pressing buttons, and those buttons make a sound. We are not aware of any telephone networks that are not able to use tone dialing (if there are any, we’d love to hear about them).

Pulse dialing is the system used on old rotary phones. While traditional landline phone networks widely support the format, many VoIP phone systems no longer support the format. Many telephone menus (“press 1 for service, press 2 for sales,” etc.) will not be able to understand signals from a pulse phone.

Which one to use?
Any fax or phone with a “tone/pulse” selector should be set to “tone” unless the phone network is rotary (pulse) only.
