Pulse To Tones DTMF Converter:
Our Pulse to Tone converter Tone Dial is a simple adaptor that is connected between the rotary telephone and the telephone jack on the wall. It intercepts the rotary dial pulses from the telephone and translates them into DTMF tones that can be detected by your modem, ONT or analogue telephone adapter (ATA) it also works on fibre.

Tone dial pulse to tone converter:
A pulse to tone converter is a device or circuit that is used to convert rotary dial pulses (also known as pulse dialing) into Dual-Tone Multi-Frequency (DTMF) tones. It is typically used in telecommunications equipment to interface with modern tone-based systems that rely on DTMF signaling.
In traditional telephones, rotary dials were used to generate pulses corresponding to the dialed number. Each digit had a specific number of pulses associated with it. For example, dialing the digit "1" would generate a single pulse, "2" would generate two pulses, and so on. These pulses were then transmitted over the telephone line to the exchange.
However, with the introduction of digital systems and push-button telephones, DTMF tones became the standard method for dialing numbers. DTMF tones are combinations of two frequencies, one from a low-frequency group and one from a high-frequency group. Each digit on a touch-tone keypad corresponds to a unique pair of frequencies.
A pulse to tone converter is used to bridge the gap between the older pulse dialing technology and the newer DTMF-based systems. It typically consists of a circuit that detects the incoming pulses, counts them, and generates the appropriate DTMF tone sequence based on the dialed number. This allows rotary dial phones to be used with modern telephone networks that require tone dialing.
Some pulse to tone converters are standalone devices that can be connected between the telephone and the telephone line. Others are integrated into telephone adapters or even smartphone applications, enabling the use of rotary dial phones with mobile networks.
It's worth noting that pulse to tone converters may not be compatible with all telephone systems or networks, so it's important to ensure compatibility before using one.
The Master Socket:
Dial phones of this era and even the retrofitted push-button phones are designed to require 3 wires to operate, modern modems have only two wires. Master sockets were required in houses, the master socket contained the capacitor required to make the phone ring, modern sockets and modems do not contain this capacitor for this reason most dial phones will not ring for incoming calls.
The Solution:
The telephones have to be internally modified and the capacitor required for ringing needs to be installed inside the telephone.
DTMF Dialing:
DTMF is an in-band signaling method using eight different frequencies transmitted in pairs. These tones are the beeps we hear when dialing. Tone dial from Antique Phones NZ a pulse-tone converter is an adaptor box which plugs into your socket then into the rotary dial phone this then converts the ‘ticks’ produced by the rotary dial to the ‘beeps’ produced by most keypad phones.
It’s a simple device that listens for the pulse clicks and converts them to DTMF tones.

Can I Dial Outside New Zealand?
Yes, but you will need a Tone Dial converter from Antique Phones NZ. Analog phones use a rotary dial, most New Zealand models are very similar on their own, these telephones would not work with modern telephone systems. The ‘pulse dial’ that it produces is not compatible with modern telephone equipment and ATA adaptors alike.
