The #ISDN stack got removed from the #Linux kernel a few days ago. That's quite the blast from the past. It's been in the kernel since, erm… *checks*… before #git and it's what the first ever #software product I built *and* sold was based on, a "unified messaging" server for #email, #fax and #voicemail. It was basically just some #python glue code duct-taping different systems together. But it worked and was used for far too many years by some.

«ISDN, Amateurfunk und mehr — Linux verliert jetzt viele alte Zöpfe:
Linus Torvalds hat es sich endlich getraut - Der Chef der Kernel-Entwicklung des freien Betriebssystems hat eine ganze Reihe von alten Treibern und Subsystemen entfernt, was insbesondere manchen Hardcore-User verärgern dürfte.»Ich behaupte mal in ~90% der Fälle ist das absetzten von alten Treibern nicht relevant aber ja, wem dies betrifft ärgert sich natürlich.

Wer ISDN/Analog im Hackcenter haben möchte, wird gebeten sich mal hier auf diesen Toot zu melden, damit wir einen geeigneten Aufstellort für die EWSD/DLU finden können #amazingtimetomarket #eh23 #easterhegg #isdn

Wir stellen gleich die EWSD im Hackcenter auf dem EH23 auf. Kramt schon mal Eure analog und ISDN-Endgeräte raus. #amazingtimetomarket #eh23 #easterhegg #isdn

Just spent half day reconfiguring #SIP trunks on #FreePBX and #Asterisk (using chan_pjsip) as one of our providers silently yoinked #IAX2 support - #VOIP is as cursed if not more so than #PSTN / #ISDN circuits, except you don't have to crawl around as much in corners and roofspaces amongst spiders, mouse-like rodents and possibly snakes (if you have them in your country), and there's less chance of ending up on the wrong side of 100-120 volts (either AC or DC, depending on whether its ringing voltage or the strong DC voltage that British Telecom and others used to send down certain ISDN lines in 90s/00s)

tonight we'll have a review of the #39c3 ISDN/PSTN network as first RetroNetCall of 2026. Join us for a chat about how the network was built, how well it worked, what improved over #38c3 and what to do better at #40c3 - https://osmocom.org/news/320 #retronetworking #ISDN

Make sure to bring your modems, fax machines, ISDN terminal adapters, phones, BTX terminals, Minitel, video phones and other #retronetworking gear to #39C3 and get connected to the on-site #ISDN network. More information at https://isdn-museum.de/ccc/39c3 #retronetworking #isdn #telephony

Last minute edition to the three additional Nokia EKSOS V5.2 access multiplexers: wooden stands/feet for mechanical protection and air convection. This is where your subscriber line terminates. 39C3 has more ISDN/POTS points of presence across the #39c3 venue than 38C3. #retronetworking #aufbauleaks #isdn
-
ISDN and POTS subscriber line termination equipment, SDH multiplexers, test equipment, fax machines, fax server, NTBAs, cables, postcards, stickers etc. fully loaded and tomorrow morning on its way to #39c3 #aufbauleaks #isdn #retronetworking

@bitnarrator schön, wenn jemand ordentlich vorbereitet mit installierten ISDN-Treibern auf die Veranstaltung kommt. #39c3 #isdn #retronetworking

@acm_redfox @vees
Usenet now that takes me back.
Here is one for all you, anyone remember Hotline Communications?Yes, the old days of the Net!
When every website did not have Ads & companies were not after your data.
When irc.microsoft.com was live & had crazy stuff on it that would shock you.
When a voodoo 3dfx was the card to have.
Yes it was not all fun as most people were on modems aka slow internet & only a lucky few had ISDN lines(I was lucky) or DSL. -
Just completed the disassembly of another two Siemens EWSD digital telephone exchanges, which are now in a truck on their way to the Telecom Museum Dresden (Fernmeldemuseum Dresden). Largest time sink was untangling the hundreds of cables (mostly with proprietary Siemens connectors).. #retronetworking #telecom #ewsd #isdn

Uns liegen geheime Informationen vor, aber hier, unter uns können wir es ja sagen:
Beim #39c3 wird #ISDN ein echt großes Ding.
Also schnell noch ein Euro-ISDN-Telefon* aus dem Keller holen oder günstig besorgen, bevor die Preise explodieren.
* Macht euch keine Sorgen, wenn ihr kein NTBA mehr habt. Wenn ihr eins habt, bringt es mit, wenn nicht @c3isdn regelt.

Die Zeiten ändern sich (nicht) ...
Während ich anfangs 2000er-Jahre eine Viertelstunde wartete, bis der gewünschte Song von #Napster mit 128 kbit/s über ISDN-Leitung heruntergeladen war, warte ich heute zwanzig Jahre später eine Viertelstunde, bis das gewünschte #LLM-Model von #Huggingface über mit 1 Gbit/s über die Glasfaser-Leitung heruntergeladen ist.

There will be ISDN (and an EWSD) at #39c3 in December this year. Our first planning meeting will be held October 5th at 15:00 CEST - anyone interested is invited to join us. Details at https://discourse.osmocom.org/t/ewsd-for-39c3-ccc-congress/2321/3 #retronetworking #isdn

We'll be rescuing another Siemens EWSD digital telephone exchange. If anyone is interested in helping us with disassembly and loading into the truck in Munich on October 23rd/24th, please let me know - more information in German at https://discourse.osmocom.org/t/ewsd-abbauhilfe-in-munchen-am-23-24-10-2025/2312 #retronetworking #telephony #telecommunications #isdn

Well then, time to properly surf the information super highway! With #ISDN of course, it is the future! No more dialing!

Does anyone happen to have any documentation for a British Telecom "Tester 420A" ISDN BRI tester.
Also known as the T4200 - seemingly made by Fulcrum Communications in the early 1990s
It's throwing some error codes at me, and I'd really like to know what they mean!

So, after spending two half days in a colocation filled with several decommissioned but fully complete [including software] Siemens #EWSD digital telephone exchanges, I am happy to report that two of them will be rescued. We've dumped the hard disks and done some initial disassembly. Full disassembly and relocation will happen in upcoming months. #retronetworking #isdn #TelecomHistory

The Internet actually ran significantly faster on Christmas day because everyone else was doing 'real' stuff and not mucking about online.
