There are vendors on the usual site who sell work-alikes of the Digium card. It's worth knowing that the Digium TDM410P FXO / FXS card for Asterisk supports pulse-dialling, so you could actually build your own telephone exchange with an old PC.

Other searches turned up a PDF Installation Manual for the KT61610 and a PDF BT Revelation Quick Reference Guide.Īnother post, further down the thread suggests a slightly different approach using an old PC (emphasis still mine): Also note that, at least in the case of the Panasonic system, you would need a "modern" phone of some description to "program" the system. From further web-searches, I've seen second-hand / refurbished examples of both the BT and Panasonic models mentioned on sale for around £60 (but caveat emptor). This suggests there are systems still in existence that can handle pulse-dialing. If you are only interested in using the phones "internally" a Minimaster 3 would fit the bill but these are becoming quite rare now.
One advantage of the Revelation is that it will convert the pulse train to DTMF if you wish to use your phones to make calls via the PSTN. Later I have seen many other options, but still the KX-T308 or KX-T616 seems to be the most reliable and easy to set up system accepting pulse and tone dialing.Ī BT Revelation PBX would be ideal for connecting your pulse dialling phones to however they do seem to be increasing in price these days. Some years ago, I had the same "problem" and ended up with buying from UK a Panasonic KX-T616 and one programming telephone for this.
I was a novice to old phones but found this straightforward to set up. If you search this site you will find the relevant threads. All the documentation is available FOC on the web. This allayed my wife's concern! The BT Revelation box was easy and cheap to source from e-bay. I used a BT Revelation wired from the house NTE5 box with a plug and socket so that all the old phones could be disconnected leaving the modern system as was. I have set up a similar system earlier this year. Skimming just a few of the responses (all from 2015, so quite recent emphasis mine): I just wondered whether there is an exchange system that can support pulse dialing? I really don't know much about phones so please do excuse my ignorance! Hi, I have a few old telephones and have always wanted to set up three or so around the house. Starting with a search for " pulse-dial pbx" led to the following question on the UK Vintage Radio forum: you would need to do some digging of your own to confirm whether any of the resources mentioned below would work for you! Note: This is where my personal experience ends. The latter requirement is likely to be more demanding. Your main problem is finding a small PBX that supports both "copper" telephone lines (doesn't appear to be too difficult) and supports pulse-dialing (instead of DTMF or "tone dialing" that modern phones use). In your case, you would probably just be using the PBX to route calls between the phones: in my (limited) experience 1, external lines would not be necessary. These days, the internal routing (at least) is likely to be network based – extensions plug into the internal TCP/IP network alongside PCs. Originally PBXs were all "copper based" – each extension around an office would be wired back to the main PBX unit using dedicated telephone wires. These come in all sizes from around four-lines up to several thousand and are used in offices of all sizes to provide internal phone calls (extension to extension) and to reduce the number of external lines needed to provide incoming/outgoing external calls (by sharing access to a limited number of "real" phone-lines among all users). Pulse-Dial PBXĮssentially what you need is a small PBX ( Private Branch Exchange). Note: I'll ignore the payphone aspect of your question for the moment: I'll just treat it as wanting to connect together a number of old, pulse-dial telephones for internal communication.
