A fix for NBN and old rotary dial phones

[admin]

I thought I would post this up in case any members end up in the same position.

I recently helped a mates mother switch from ADSL to NBN (FTTN). All good, except for one problem. As well as a modern hands free phone, she also had an old Telecom Bakelite rotary dial phone from the 50's/60's.

As soon as the NBN was connected, it stopped working. It wont work because it is designed for use on the PSTN network that we have always had, and under the NBN we do not use it.

I said I would do some research and see if I could come up with a fix , and came across this item


Basically, you plug it between the phone and the line and it converters the rotary dial signals in to digital signals which the NBN line can understand. Amazingly, it also adds features - you can store numbers ! Example, you can store a number to speed dial. Its easy to set up, and to use speed dial, simply dial the speed dial number (example 2) and hold it for 2 seconds. It then dials the preset number.

A great product.

I don't see why it wouldn't work. Up until the NBN, loop disconnect dialling was an accepted form of signalling, even though it had largely been superceded by DTMF from the 1980s onwards.

I assume admin was referring to "between the NBN line" as it being from the modem which would now be VoIP... 99% of VoIP devices (including modems) only allow for either digital dialling or DTMF dialling. AFAIK the FTTN NBN Line is only used for the NBN Data, not voice or audio...

Correct,

The only device that connects directly to the NBN line is the NBN modem, the output of which connects to distributed premises cabling and devices.

The NBN modem 'telephone' port is essentially a digital-analogue converter, but it does not work with outdated technology of decadic/pulse dialling, which is where the device admin posted helps.
