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.

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

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

Everyone helping the c3isdn team at #38c3 is invited to meet at 15:00 today for a group picture in front of the #EWSD #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.

Amazing project by kev009 to rescue an entire #Lucent 7 R/E 5ESS Telephone Switch - a "slightly" larger feat than the various #EWSD rescue projects we've seen here in Germany over the last 12 months. http://kev009.com/wp/2024/07/Lucent-5ESS-Rescue/ #retronetworking

yay! First successful calls from an #EWSD exchange in Czech Republic via a SS7 (MTP2/MTP3/ISUP) interconnect over E1 PRI TDMoIP to the yate that's running the core of our OCTOI Community TDMoIP network! https://osmocom.org/projects/octoi/wiki/Community_TDMSS7_Network #retronetworking

In case anyone wants to join me trying to debug a SS7/ISUP interconnect between a Siemens #EWSD and a #yate softswitch (in our OCTOI community TDMoIP network): I'll be doing some of that live at https://osmocom.org/RetroNetCall tonight at 20:00 CET. #retronetworking

It's RetroNetCall time again: Join us at 20:00 CET tomorrow (November 1st, 2023) to chat about #retronetworking technologies and get some updated on the #EWSD rescue as well on my recent acquisition of the 1992 "BildTel 001" #ISDN video phone https://osmocom.org/news/224

@1000millimeter @juela_the2nd @OverBoing @Trrailchaser die besagte #EWSD sollte von 2001 sein, kann aber auch sein dass das nur ein Umzug von einem anderen Standort war, und sie älter ist. Müsste jolly mal die Baugruppen auf Datum hin untersuchen.

This is how it looks from above, where a Siemens #EWSD used to be switching millions of calls for decades. It's now nicely documented, labeled and disassembled and will be carefully reassembled in the home of a private collector. Something sadly no museum known to me has managed to preserve so far. #retronetworking

A few hours later: First 4 racks disassembled and hundreds of cables (all pre-confectioned to some long length with excess cable length rolled up below the floor) waiting to be untangled and sorted. #retronetworking #EWSD

Our school district is pushing back our high school start time from 8 AM to 8:40 PM next year. We mainly did it because of a shortage of bus drivers but it’s great to see that it will also have health benefits for our teenagers: https://www.scientificamerican.com/article/high-school-students-need-more-sleep-and-later-school-start-times/ #VT #Vermont #EWSD #education #Sleep

The projected tax rate, before the common level of appraisal (CLA) is projected to decrease for the 3rd straight year - and for the 5th time in six years.

The #EWSD School Board is proposing a budget for 2023-24 that is a 8.5% increase over last year but could have a negligible impact on tax rates
