Building a related E1 interface mostly uses [still] available LIU (Line Interface Unit) integrated circuits. @tnt took it one step further and started to think along the lines of what if I had to do my own LIU analog circuit design? This meeting will have the following schedule: 20:00 meet + greet 20:10 presentation as outlined above 21:00 unstructured supplementary social event [3] Attendance is free of charge and open to anyone with an interest in Osmocom or open source cellular technologies.

Best regards, Harald [1] https://osmocom.org/projects/retronetworking/wiki/RetroNetCall [2] https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCall [3] this is how we started to call the "unstructured" part of osmocom developer conferences in the past, basically where anyone can talk about anything, no formal schedule or structure. -- - Harald Welte <laforge(a)osmocom.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Retronetworking exhibit @ VCFB 2022: Help wanted

by Harald Welte

Hi all, Vintage Computing Festival Berlin 2022 is scheduled for October 8+9, 2022 It would be great to put together an exhibit there, re-using the small rack based setup that was at the 2019 CCC congress (Auerswald PBX, Freeswitch, Portmaster3) as well as a number of modems / ISDN-TA etc. to show BBS dial-up and the like. I have all the equipment and can work on the preparation/setup, but I think it would be very helpful if this was not a one-man show but if somebody would be around to help particularly on-site when there are visitors looking for demo, explanation, help, ... Registration deadline is September 7, as indicated at https://vcfb.de/2022/call_for_participation.htm Before we go into what we could/should demo, I would like to get a feeling if anyone is interested in helping out.
