@lpbkdotnet I don't know if I'm any help, but I love the idea of reviving #isdn hardware
Is anyone able to lay their hands on a firmware image for a Samsung Ubigate IBG1004?
It’s an #isdn to #sip #telephone gateway, and the one I’ve got seems to be corrupt and won’t decompress.
My usual haunts for firmware images are coming up blank.
The filename will be something like `iBG1004_Advanced_1.6.1.9.Z` - but I'm really not too fussy about the version number!
Please boost if you think you have followers that can help!
@vwestlife #Funfact: In #Europe, #Cband dishes weren't common so #SatelliteInternet used simiar #Tuner cards with #VSAT terminals, oftentimes acceptibg downlinks from regular commercial #TV #satellites...
I've got one of those...
And yes, I used that to share a #dialup connection with multiple devices, because they can do that!
@GossiTheDog I remember the feature, but in retrospect it seems it was introduced without any safeguards here in Germany - and became maybe a 70+% standard (most people used it by default) when #ISDN became a thing. #old
The German language podcast "Besser Wissen - Alles über ein Netz" by @Golemde chatting with me about #ISDN history / #retronetworking has just been released at https://besserwissen.podigee.io/120-isdn
Oh, der #Golem #BesserWissen #Podcast spricht in der aktuellen Folge mit @LaF0rge über #ISDN.
Dabei geht es neben dem historischen #Bundespost/Telekom-Netz u.a. auch um das ISDN-Netz auf dem #CCCamp und dem #38C3 mit Exkursen zum analogen #Telefonnetz und #Modem / #Akustikkoppler / #Datenklo / #DSL / #Musiktaxi.

At #38C3 I received a new addidion to my #ISDN related #retronetworking collection of vintage tech: A Siemens K4301 Up0/S0 error meter: https://osmocom.org/projects/retronetworking/wiki/Siemens_K4301

Today (well, yesterday by now) we managed to further complete our #38c3 SDH network consisting of STM1 add-drop-miltiplexers that carry the E1 based V5 interface from access networks to the EWSD #aufbauleaks #ISDN #retronetworking

Thanks to gruetzkopf we now already have 6 SDH ADM (add-drop multiplexers, specifically Ericsson/Marconi OMS860) deployed. We're using a SDH (synchronous digital hierarchy) backbone to transport the V5 interface of our #isdn between #EWSD and Access Multiplexers.

@nblr @Badscrew it does SIP in addition to H.323 as well. Indeed, ISDN BRI for channel buindling up to 384k and over IP it does 786k. But of course I'm only interested only in the #ISDN side of things. #retronetworking
Does anyone have software for the Tandberg MXP 1000 TTC7-12 ? My hardware has ISDN BRI circuits but the installed software omits any ISDN configuration...

Wer mal in einem alten Telekom-Katalog blättern will: https://archive.org/details/telekom_katalog_1994_1995 - mit Xitel, Delegatic, Euro-ISDN, Datex-J, Cityruf, C-Netz, ISDN-Adapter für Parallel-Port, u.v.m. #retronetworking #ISDN #Telekom
Zum Einstimmen auf das ISDN-Netz auf dem #38C3 hier ein paar ISDN-Nachrichten von vor 34 Jahren. #retronetworking #ISDN
Ihr kommt zum #38c3 aber habt kein Zeitgenössisches Endgerät (Analoges Modem, Telefon, ISDN-Terminaladapter, Faxgerät) mehr, um Euch am @c3isdn #ISDN + Analogtelefon-Netz anzuschliessen? Deutschlandweit werden Faxgeräte gegen Abholung verschenkt. Schaut mal auf https://www.kleinanzeigen.de/s-handy-telekom/faxgeraete/sortierung:preis/c173+handy_telekom.art_s:faxgeraete oder anderen Kleinanzeigenbörsen und holt euch eines. Viel Spass am Faxgerät!
