We're happy to announce the next incarnation of RetroNetCall, the retronetworking oriented spin-off of OsmoDevCall
This time, laforge will be presenting on DATEX-L, the German circuit-switched public data network which existed from 1967 (!) onwards.
For more background see CSPDN__Datex-L.
Topics include (not limited to)
- timeline / history
- network architecture
- applications

This time, tsaitgaist will be presenting on USB hub for device testing.
When: Wednesday, December 21, 2022 from 20:00 CET
Abstract:
During hardware development and testing you often have numerous additional devices attached to it: serial debugger, programmer, logic analyzer, and so on.
A commercial USB hub should be enough handle that, but it often comes with limitations.
So why not have a USB hub designed for assisting in hardware development and testing: flat 7 ports, impedance controlled, with current and ESD protection, and remote power control for USB and higher voltages.
The result is open source and available at https://git.cuvoodoo.info/usb_hub.

Millenia (on the IT timescale) after deDECTed and about a decade after the now abandoned OsmocomDECT project, a group of people in and around Osmocom started to play with DECT again. There's no big plan, or no specific goal, other than getting more hands-on hack value with consumer DECT hardware, at its lowest levels.
It started with some innocent ringtone-hacking on a Gigaset C430 by manawyrm, followed by a much appreciated fix for the long-standing bug of Gigaset DECT phones radically over-charging (and eventually killing) their NiMH batteries (see Gigaset_C430_Hacking).
Initially, this required un-soldering and re-programming the SPI flash. After the debug UART was identified on the two test pads accessible from the battery compartment, manawyrm and tobleminer have figured out how to load code into the processor (see also ChipsUsed). Some initial related tools have been created and collected in the https://github.com/TobleMiner/dialog-sc14441-uart-boot repository. Using this you can execute your own code on the Gigaset C430, C300 and likely many other DECT phones using the Sitel (formerly NatSemi, now Renesas SC14xxx chipset family. Those who have had an eye on DECT for a longer time will recognize that this family of chips was also used in both the deDECTed as well as the OsmocomDECT CoA driver. It is also used in the Aastra/Mitel RFP base stations (see this OsmoDevCon2019 talk on RFP base stations and the 36C3 #mifail talk).
It's yet unclear where this will lead to. But it definitely is nice to see some people excited about playing with DECT devices again. If you want to follow developments in real-time, join us on the #osmocom

we're happy to announce the next incarnation of OsmoDevCall. Based on the recent polls, the timing has shifted to every 3rd wednesday of the month.
This time, fixeria will be presenting on MS/BS power control support in OsmoBSC/OsmoBTS.
For those not entirely 3gpp-acronym-savyy: That's how the uplink (phone -> network) and downlink (network -> phone) transmit RF power level is adjusted during an active call in GSM.

We're happy to announce that sysmocom has achieved to obtain funding from Open Technology Fund for a variety of enhancements and improvemnts of the Open Source Cellular Network Infrastructure sphere.
The funded activities are in the following areas:
- Better integration between the Osmocom 2G/3G core network elements and the open5gs 4G EPC (evolved packet core)
- Improving the stability, quality and maturity of the open5gs EPC by implementing functional test suites in TTCN-3
- Establishing interoperability with various base station hardware
- Support three trial deployments in rural Mexico with our partner Rhizomatica
- Organize a series of webinars for security researchers on how to use our tools for furthering their research projects
See also the project description at the OpenTechFund website
We'd like to thank OTF awarding funding to our proposal.
We'd also like to thank Rhizomatica and specifically Peter Bloom for all his help in putting together the proposal.
Osmocom now has an official fediverse account
@osmocom@fosstodon.org
which we will be using to send updates on osmocom project developments, releases, events, etc.
Web interface is available at https://fosstodon.org/@osmocom
We'd like to thank fosstodon.org for providing a Mastodon instance catering to the FOSS community.
