Вадим Яницкий axilirator at gmail.comHello, Harald, thanks for the answer. first of all, CalypsoBTS is not an active / maintained / stable solution > but more lik an (mindbogglingly amazing!) Hack. Yes, I know that CalypsoBTS is not stable solution. But currently I am a student and I have no so much money to buy anything more powerful. Furthermore, I am interested in this for research purposes only, not for creating public land mobile networks. As you are the first person to report using the code to this list for > quite some time, it would be great if you had some time to re-base, test > and submit it. As I previously said, I also tested master branches. Here are the results: * When I start OsmoBTS I often see this message in OpenBSC log: "Lost some E1 TEI link: X X" from bsc_init.c. In this case my MS can not connect to the test network and I have to restart OsmoBTS until this message will no hide. * When the Location Update process I always see this error: "input/ipaccess.c:277 Bad signalling message,sign_link returned error". But a phone successfully registers in the network. * SMS, USSD and Silent SMS works fine. * When TS1 assigned TCH/H I can call to another ms or LCR. DTMF works. * When TS1 assigned TCH/F I can use FR codec and call to LCR. * PDCH does not work on this BTS. * RRLP works. * ISMI detach works but as in case of Location Update I see "Bad signalling message..." error. * It seems, the network works more stable when battery capacity is 100% and backlight is disabled. If I understood correctly, osmobts-trx was just moved from obsolete repository to the master. Now I am reading the source code and trying to fix this bugs. I have one thing in my mind for a long time. Is it possible to serve a PDCH lchan on TS1 instead of TCH (in case of this "powerful" BTS)? I have tested OsmoSGSN+OpenGGSN with one PDCH channel on TS1, but it did not work. With best regards, Яницкий Вадим. 2015-12-06 18:14 GMT+06:00 Harald Welte <laforge at gnumonks.org>: > Hi Vadim, >> >> first of all, CalypsoBTS is not an active / maintained / stable solution >> but more lik an (mindbogglingly amazing!)
