Hi Alina,
First, we are tying to connect our BTS directly to OsmoBSC. I'm trying to use configuration for Siemens Bs11,
I recall Dan saying that your Siemens BTS is not BS-11 but some other, presumably bigger model. Do you know for certain if it speaks the same flavor of Abis as BS-11? Are you (or were you) able to capture any Abis traces from this BTS working with its native BSC, to see if the Abis flavor matches expectation?
Also a question for Osmocom community: it is my understanding that (almost) no one has been playing with BS-11 hardware in a long time. When was the most recent time that someone tested it and saw that it still works? Do we as a community _know_ that Siemens BTS support still works and hasn't been broken by bitrot?
but I have problems with channels configuration in DAHDI. Do you have any advice for dahdi configuration?
I don't have any experience with DAHDI yet: I expect to have a need to start playing with DAHDI soon, but I haven't got there yet. Yesterday I gave a RetroNetCall presentation on my Nokia TRAU adventures (you can watch the recording in BigBlueButton), and the current status is:
1) When I get the additional parts for my TRAU that do the actual E1 interfaces, I will need to connect those E1s to the Digium TE405P card I recently bought, and will need to learn DAHDI then.
2) Harald graciously offered to send me a Nokia InSite BTS (small like nanoBTS, but E1-based); whenever I receive that BTS and find the time to play with it, I will likewise need to learn DAHDI.
Thus I expect to have more DAHDI knowledge in a few months, but I am not there yet.
