PABX working with older phones

- Video demonstrating rotary dial phones etc connected to a modern PABX (Panasonic TES824), along with discussion of 'reversed pulse dial numbering' in New Zealand. See one of these being used in a cover version of The Big Bopper's hit 'Chantilly Lace' here: • 'Chantilly Lace' - Big...

I have a couple of small PABXs here at the house. I'm just a stickler about programming in other extensions on speed dial numbers.
I love the two "reverse" phones. Would love to have one of those!
Great collection. Thanks for sharing!
I use a grandstream HT812 VoIP adapter and raspbx on a raspberry pi as the PBX. Interestingly, the HT812 has an option in the pulse dialling menu to choose New Zealand.
Thanks for sharing that info; interesting about the pulse dialling option for NZ, but I guess it makes sense given NZ is a bit of an anomaly in that regard; cheers
@@Songwriter74 There's another option in the menu for Sweden, so maybe they have a slightly different system too
The phone you called type 200 PERT phone was called the Viscount here in the UK. Available in quite a few variants and quite popular.
Hi, I never realised that; having worked in the UK briefly I came across some alternative names in telecommunications, but 'viscount' for that phone is new to me - thanks for sharing
Hi Craig, I have a Panasonic KXTDA30 which is in alarm mode. I possibly need the Panasonic software to reprogram it. Can you possibly help me source the software. Regards Rob.
Hi Craig, great informative video, do you know if the Panasonic KX-TEA308 Advanced Hybrid Telephone System also supports the old pulse disk phones as like you I have many older phones that I want to link up as an intercom system!
Many thanks, Jon
Hello Jon, yes it appears that the KX-TEA308 does allow for the connection of older pulse/rotary dial telephones, but obviously certain features that require '*' and '#' will not work. There is a note to that effect at the bottom of the page of the online manual - see this link:

Cheers
@@Songwriter74 that’s brilliant thank you! I don’t need the special features , it really is just to host my vintage phones as a stand alone internal system in my home. There won’t be a landline connected to it at all.
Many thanks for your help 👍🏻😃
@@Songwriter74 hi Craig, I have gone ahead and purchased the KX-TEA308 from eBay so hopefully should arrive soon. It doesn’t come with the programmable telephone but is it relatively easy to set up my pulse phones to work without it?
Cheers, Jon ☺️👍🏻
I believe the push button phone would be an NZPO 100? Only guessing given the metal base. Based on my collection the type 101 was the later model and had a black base with the model number physically stamped onto the metal as opposed to the sticker used on the earlier 100.
I'm not so sure - the NZPO Type 100 (Type 746 in Great Britain?) refers to the rotary phone with the clear plastic dial - I do not know what model the similar looking push-button phone is. Here is a useful link: www.mattmillman.com/info/a-crash-course-in-using-gpo-telephones-in-the-modern-world/
Then again, I see this video on TH-cam labels the green push-button as GEC model 746/NZPO Type100, so I am a little confused: th-cam.com/video/8h_uE1rvq4E/w-d-xo.html
@@Songwriter74 As far as I can tell there is no GPO equivalent to our pushbutton 100/101s. The UK's buttons were more rectangular in shape in contrast to our square ones, which I suspect were borrowed from (or at the very least inspired by) the Western Electric design. If you take apart the phones you can discover that the plastic shells are identical (including the hole cut for the faceplate and associated dialing mechanism). The internal wiring is identical regardless of which mechanism is used for dialing. The NZPO, unlike the GPO was really hell-bent on sticking with one design when it came to that era of telephone. A prime example of this is, of course, our wall mounts being a rotated desk phone with a bit of metal to hold the handset in place (Any desk phone can be converted into a wall mount and vice versa).
Most of that is just based on my observations as there are really no sources online when it comes to the NZPO. The long and short of it is that there was no specific variant based on dialling mechanism and the 100/101 difference could just be a circuit board difference.
I've just purchased an identical Panasonic tes824 because of this video. I've got the system phone on order as it doesn't work at present. Did you have ti alter much on yours to get it to work? Thanks for posting.
Hi Paul thanks for your comment; I know I made a few changes in the programming when I got the PABX in order for it to be more compatible with NZ phones - if I recall I think this was to do with the ring cadence and the pulse setting for rotary phones. In the end I re-labelled the dial on the rotary phones to reflect the 'reverse numbering' we use here.
I also made changes to the extension numbering, so that each phone had two digits instead of three (i.e. 11, 12, 13 etc) and I assigned '0' to the operator, seeing as that's what is traditionally used here in NZ. This meant that the number to access an outside line became 9, though for the purposes of this exercise I only have the system set up for internal dialling. However I did program the main phone to select an external line as soon as it goes off hook; I then routed a spare extn back through to the first CO line port on the PABX for test purposes and to MIMIC external calling/call being received from outside.
So overall it was mostly the 'numbering plan' that I made changes to. Since the PABX I bought came with the software to re-program it (on a disc), I was able to load the software and do this via my laptop, which was easier than using the display phone - this latter phone I purchased separately since the PABX didn't come with one.
I actually purchased another one of these Panasonics for around $1 subsequent to getting the first one, thinking this second one was more compatible with the NZ market, but for some reason it had a different dial tone which I couldn't seem to change to match what we are used to hearing here. If I had the need or desire I could connect this PABX via the CO line port on the main unit and effectively create a secondary exchange.
You might have to make additional changes to suit your system depending on the country, but I hope some of the above helps and is of interest. Cheers
@@Songwriter74 That's really helpful thank you! I'm going to play around with the system again later today. A really helpful and enjoyable video thank you. I've wanted to set my old phones up on an internal system for years. Just need to get the pulse dialling working now and I'm nearly there. Great job setting yours up so well.
You're most welcome
awesome Phone the wallmounted phone this ericsson N1900 phone from the uk and push button phone is gpo 8782 phone from the uk
Hey thanks for the info. I never knew Ericsson was the manufacturer - I see there's a few of the N1900's (from the 1960's) for sale in the UK on Ebay.
cause on the base of your wallmounte phone it has the Model mumber N1900 on the bottom of the phone thats the way you can tell if its a Ericsson phone cause all Ericsson phones have model number starting with a N
Going off of this, that wall mount would definitely predate the 100/101. My hunch is that these were manufactured in the UK and shipped over to New Zealand. This was the case with the Bakelite wall mounts, desk phones and pyramid phones to name a few (This had the side effect of a few GPO customers accidentally recieving phones with the inverse numbering plate, much to the dismay and confusion of the subscriber). I think it's more than likely that there is no NZPO specific name for it and it was the last model before New Zealand manufactured 100s came onto the scene.
The GPO version was designated the 746.
