#isdn — Public Fediverse posts

Yet another nice Asianometry video, this time history of DSL.

Of course his (loosely paraphrased) comment on "DSL not widely used anymore but it'll remain in the backwaters for a long time" is peak hilarious to any German.

Worth your time. Got some fun comments too.

After some hiatus, we're happy to announce there will be a new RetroNetCall on July 8th, 2026 at 8pm CEST. Andreas "jolly" Eversberg will tell us how he finally managed to enable and play with the LI (Lawful Intercept) features of the Siemens EWSD digital telephone exchange. See https://osmocom.org/news/327 #retronetworking #telecom #EWSD #ISDN #retrocomputing

Last #repaircafe #repair: local #ISDN phone exchange with audio issues from approx. 2004. Three electrolytic caps were definetely bad with internal resistance of at least 20 Ohms. They were right next to voltage regulators that idle at 50°C. No way to test it, but voltages are stabile again and the ripple voltage is now at <1% so I hope that was a successfull fix.

9 Watt idle for 22 Years, thats nearly 2 MWh!

So langsam scheint auch die Unterstützung für mein #ISDN Telefon aus den Routern zu verschwinden. So sad. Und auch das Fax empfangsfähig anzuschließen wird immer mehr zum Abenteuer, weil die Audiocodecs vom Voip sich so schlecht mit dem Faxcodec vertragen.
Für ein paar Cent billiger haben wir ohne Not den besten Telefonstandard, den wir je hatten, in die Tonne gekloppt.

Ich glaube nicht mehr an "technischen Fortschritt". Ich glaube nur noch an Gewinnoptimierung allerorten.

Ich hab schon wieder eine Glasfaser-Challenge: Ein VDF-Kabelanschluss wird durch DTAG-FTTH ersetzt, und die Fritzbox Cable durch ein Glasfaser-Modem und ein Speedport-Ding.
Ich war über Jahre mit Fritz sehr zufrieden und denke jetzt schon darüber nach, Speedport (oder beides) durch nen neuen Fritz zu ersetzen, u.a. weil ich im Haus noch eine ISDN-Anlage habe.
Ich weiß nur nicht: Welche Fritzbox (mit Glasfaser oder ohne) nehm ich denn dafür?

Edit: Wohl die 7590.

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.

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

Tomorrow (2026-04-01) night we'll have a RetroNetCall about the initial planning for the ISDN network at the CCC congress this year. #40c3 #retronetworking #pstn #pots #isdn #ccccongress https://osmocom.org/news/325

#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)

#Telecoms

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

4 B-channels and some table space please! Bringing a T-View and a DisplayTel. @c3isdn #ISDN #39c3 @LaF0rge

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
