I never knew Missouri had its own telephone museum, until recently. Today I made the 100-plus-mile trip to St. Louis to visit it, allowing me to see its vast collection in person. Stay tuned for a blog post on the Jefferson Barracks Telephone Museum to see some cool nerdy stuff. #telephonehistory #techhistory

I had the green one on the bottom. Tag yourself! 😂

Seriously, it was a bit janky but I was delighted as a teenager that I could disconnect the bell so it wouldn't wake me up if someone called before 11am on a weekend. I can't remember if it was *designed* to be turned off; I definitely opened it up more than once because I could and because there was a loose wire in it.

This is at @connections -- I have so many photos to process!

A set of glass shelves filled with old school rotary dial phones (and a few push button ones) in many different colours.

Hey #telephone people - does anyone have a recording of a call to any of the 1990s "chat and date" services (eg, 0891 505050 - or 0891 343434)

https://www.youtube.com/watch?v=7wBifkGjrx4

The TV adverts were great, but I didn't have enough money to call one!

I'm told they were a maze like menu system, that took ages before you could chat with anyone

I'd like to make a realistic recreation, so If you have a recording you can share - please DM me! (discretion assured!)

Just sorted out a light-touch refurb on this GPO Tele 745 weatherproof #phone

The handset is a bit faded, scratched and tatty, but it’s had a good clean and a new cord, so it’s perfectly serviceable for #emf2024 and suitable @cutel mischief.

I bought this with the intention of installing it in the garden, it really needs a strip down and repaint… but I can get to all that after #emf 😀

Metal, coffin shaped dial telephone propped up on the workbench with the door open.

Now this is a nice find!

I've been passed a scan of a notebook from the late 1950s containing details of all the #telephoneExchanges in the UK

This sort of information was used by #telephone enthusiasts (UK #phreaks) to navigate their way around the toll (trunk) network

There were various techniques to get yourself onto a trunk, but once you were there the dialling codes in this notebook would get you anywhere in the country!

#phone #telephoneHistory #telecoms #phreak #telephoneHeritage

Scan of a typewritten page from a notebook. It appears to have been spirit duplicated, and the typewritten text on the left of the paper appears in blue.

This page lists a number of exchanges from Dartford to Dover, along with a code describing how to reach that exchange.

On the right is a handwritten key, describing how to decode the number info.

t = Toll-A
k = Kingsway
f = faraday
(All exchanges in London that had known vulnerabilities at the time)

m = manual (indicating the exchange didn't have automatic equipment yet)

o = ?? answer on dialling (?)

My new bedtime reading has arrived…

In the UK, AC13 telephone signalling used pulses of 2280Hz to represent the digits of a dialled phone number, call progress state etc.

This training document from 1983 was pretty late in the lifespan of in-band signalling like this, which had been around for 20+ years by this point.

It’ll be fun reading this from a “what would it do if I poked $thing at $time” point of view

#telephoneHistory #telecomHistory #telephone #telecoms #phreak #phreaking #phones

A4 document with a white cover, text reads:

Signalling system AC13 principles and system operation
British Telecom, BTHQ/IT 7.2.2C, issue 1, Jan 83

In the document number I believe “BTHQ/IT” = British Telecom HeadQuarters, Internal Training

This is extremely silly.

I have a Nokia 105 #phone. No data or apps. Just a plain, dumb, mobile phone

Using a sim from aa.net.uk I've connect it to the C*Net VoIP network https://ckts.info

It's accessible on a CNet number, and can place calls just like any other phone on CNet!

Do I need this?
No.

Can it make normal calls?
Absolutely not!

Is it useful?
Not in the slightest.

Is it cool as heck?
Absolutely!

I'll make a demo video later…

I love the product names in this extract from Telephone Rentals document "EP2/4055 - S50 - FACILITIES, DICTATION RECORDING" (30th Nov 1964)

It lists approved suppliers of centralised recording equipment, to be connected to their internal telephone systems

Centralising the recording equipment was much cheaper than duplicating it for each exec.

A central typing pool would retrieve the recordings, type them up and send them out

#telephoneHistory #telephone #phone #telecoms #phoneExchange

Typewritten document, text reads:

Examples of equipment utilising this method of control and known to be suitable for connection to our PAX installations are as follows:-

1. Dictaphone "Telecord"”
2. Aga Dictating Machine Co., "Agavox"
3. Shipton "Intercorder"
4. E.M.I. "Eminet"

Oh yeah! I was posting Christmas telephone stuff this month wasn't I..

On Friday I mentioned that The Hull Corporation telephone company launched their Santa service.

Well, here are three examples of the recorded messages that kids could dial up and listen to:

In 1952, The Hull Corporation (who provided #telephone service in #Hull, UK) launched a recorded message service where children could dial 211211 and listen to Father Christmas tell them all about his festive preparations!

The recording included a message from Santa, carol singing, and stories written and performed by Hull Telephone Department Employees.

There's more info and a lot of photos here: https://www.kcom.com/home/discover/categories/kcom-news/take-a-look-back-at-the-spirit-of-kcoms-christmas-past/

Text reads:
Santa Clause with David Whitfield will be on the telephone tonight, Friday night and Christmas eve, 5:30pm to 8:30pm.

This christmas tree made from a telephone cable was an exhibit at the “Young People's Exhibition”, Imperial Institute, London, 29 December 1936

The cable dates from before PVC insulation was widespread. Each wire was individually insulated with paper, and the whole cable was covered in a lead sheath.

Arranged in “pairs” there are 6024 wires in total.

Large “tree” made from a dressed telephone cable, adorned with a handful of Christmas lights.

A group of a dozen or so children stand around it with an adult. Although the scene is indoors in an exhibition hall, all the children are wearing warm coats and some of them are wearing wellies.

One of the children is pointing at the tree.

There is a plaque under the tree which is unfortunately illegible.

Happy 31st birthday to the SMS text message!

The first message was sent on this day in 1992

What’s this mystery object stuck to my telephone?

This is what a Phonair #telephone #handset #airFreshener looks like installed in it's natural envrionment, on the mouthpiece of a lovely red #GPO706

#phone #telephoneHeritage #telephoneHistory #vintagePhone #vintageTelephone #telephoneSanitiser

Close up view of the mouthpiece of a GPO 706 style British dial telephone.

Clipped to the centre of the mouthpiece is a small, silver, perforated, disk shaped capsule. It's supported by 3 pegs that clip into the sound holes.

The disc has "PHONAIR" embossed around it

Does your #telephone #handset smell of old feet for some reason?

Stop sniffing it like a weirdo, and install a “Phonair” telephone freshener!

This little silver puck clips on to the mouthpiece of your GPO telephone and makes it smell lemon fresh for up to 3 months!

Also available in rose and “original” flavour.

(Not suitable for trimphones)

I spent today with a friend troubleshooting the “non-multiple extension phone” relayset he’s built for his GPO HES4 demo

It’s a reproduction of the original “House Exchange System No4” equipment, which is impossible to find these days.

We confirmed the fault, know what the cause is (his electronic #PBX can’t source enough current to operate the differential D relay) but we can’t fix it… yet!
