IP Access nanobts dropping OML link to OpenBSC
by Dingani Brian Nkala 21 Oct '12

21 Oct '12

Hi All, I'm very new to OpenBSC and nanoBTS (but have quite a bit of experience in telecoms in general). I recently acquired a brand new ip.access nanoBTS (nanoGSM) for a project I'm working on and I promptly installed OpenBSC on Ubuntu 11.04 successfully without any headaches. So far I've managed to do an "ipaccess-find" and found the BTS, and also set the Unit ID of the nanoBTS + OML address using the "ipaccess-config" utility. My problem is, when I startup osmo-nitb, I can see the BTS trying to connect and then it sends a NACK and OpenBSC drops the links. Below is the output I get on the screen when I startup osmo-nitb: /home/beta/libosmocore/openbsc/openbsc/src/osmo-nitb# ./osmo-nitb -debug=DRLL:DCC:DMM:DRR:DRSL:DNM:DSMS:DMNSMS:DDB:DMEAS -c openbsc.cfg DB: Database initialized.

Fwd: Open-source telecom T-shirts
by Alexander Chemeris 20 Oct '12

20 Oct '12

Sorry to those who receive this message twice. I hope Osmocom community finds this small effort interesting as well. ---------- Forwarded message ---------- From: Alexander Chemeris <alexander.chemeris(a)gmail.com> Date: Fri, Oct 19, 2012 at 5:15 PM Subject: Open-source telecom T-shirts To: umtrx <umtrx(a)lists.osmocom.org>, openbts-discuss(a)lists.sourceforge.net Hi all, We're thinking about making T-shirts with open-source telecom. I've posted a call for ideas in my OpenBTS blog - please contribute. Telecom needs more openness and you could help us promote this! http://openbts.chemeris.ru/2012/10/reklama-open-source-telecom/ We plan to give them for free to the first 10-20 UmTRX buyers. Then you'll be able to buy them from our web-shop or from one of our friends and distributors. If you proposal gets printed, you'll get a free T-shirt as well. PS If you know a good online T-shirt printing service in US or Europe - drop me a line. I've never done this in US/Europe before. -- Regards, Alexander Chemeris.

BTS hardware trade.
by Andrew Back 19 Oct '12

19 Oct '12

Hello, Is there anyone who has 1800MHz or 900MHz hardware and that would be interested in swapping it for 1900MHz kit? Probably a long shot but worth asking! If so, please contact me off-list. Cheers, Andrew -- Andrew Back http://carrierdetect.com

CSD support for openbsc with the BS-11
by Tobias Engel 18 Oct '12

18 Oct '12

Hi, I just pushed a "tobias/csd" branch to both the openbsc and libosmo-abis git. If you check out those branches you should be able to make CSD calls with a BS-11 and the following parameters: V.110, 9.6kbit/s, transparent mode. The AT-Command to activate this mode is AT+CBST=71,0,0. (If you see an ERROR when entering this command, your phone's baseband most likely doesn't support transparent mode. One of the few exceptions seem to be MediaTek and TI.) There is no Interworking Function in the code - the V.110 frames simply get sent from one phone to the other. This should not be a problem as long as both sides use the exact same parameters. The openbsc tobias/csd branch is based on Harald's laforge/csd branch which already adds code for setting CSD channel modes. Many thanks to Dieter Spaar who found out why I was only seeing garbled data on the uplink, and also to GSMK who let me use lots of my time there to figure out this CSD stuff. Next stop would be to implement RLP to also support V.110 non-transparent mode which is supported by almost all GSM basebands. -Tobias
