nanoBTS with newer firmware (patch)
by flw＠smart.ms 17 Feb '12

17 Feb '12

Hi list, I just had tried to connect a nanoBTS model 165a with firmware v142b13d0 to openBSC. The BTS does connect to OML, starts with the PING - PONG and identifies itself, but nothing else happens (i.e. no software activate request). As recent firmware requires an explict IDENTITY ACK after answering an IDENTITY REQ with the RESP, I made a small patch to ipaccess.c - and voila, BTS connects OML, gets initalised (at the second attempt as usual - I'll try to dig into this later), establishes RSL and is happily showing green. Feel free to integrate the attached patch. Best regards, Flo.

Newbie question: CM Service reject
by Don Fanning 11 Feb '12

11 Feb '12

Hello All, After some trials and tribulations, I think I got my OpenBSC+LCR+Asterisk compiles and working. The MS connects once I spoof the proper MCC/MNC for the foreign SIM I have (to ensure that no one else can connect within my area). Then when I try to make a test call to an asterisk extension, it give me the following: Thu Feb 9 18:55:58 2012 <0004> abis_rsl.c:1318 (bts=0,trx=0,ts=2,ss=0) Activating ARFCN(514) SS(0) lctype TCH/F r=CALL ra=0x4f ta=1 Thu Feb 9 18:55:58 2012 <0004> abis_rsl.c:1064 (bts=0,trx=0,ts=2,ss=0) CHANNEL ACTIVATE ACK Thu Feb 9 18:55:58 2012 <0000> abis_rsl.c:1490 (bts=0,trx=0,ts=2,ss=0) SAPI=0 ESTABLISH INDICATION Thu Feb 9 18:55:58 2012 <0002> gsm_04_08.c:858 <- CM SERVICE REQUEST serv_type=0x01 mi_type=0x04 M(210271915) Thu Feb 9 18:55:58 2012 <0002> gsm_04_08.c:800 -> CM SERVICE Reject cause: 2 Thu Feb 9 18:55:58 2012 <0001> gsm_04_08.c:114 (bts 0 trx 0 ts 2 pd 05) Sending 0x22 to MS.

Setting up a fixed IP for the ip.access nanoBTS using ipaccess-telnet
by carcelle 08 Feb '12

08 Feb '12

Hi dear list, After sometimes to get it work, I have set-up a fixed IP on my ip.access nanoBTS and thought that could be helpful to share the howto/tuto from this experience : The best way for linux user is to use the ipaccess-telnet tool from the git (git clone git://git.osmocom.org/libtelnet.git) rather than BTS installer from ip.access which doesn't easily allow the access to the flags of configuration (i.e. NV attributes) of the nanoBTS. 1/installation of ipaccess-telnet I have installed it on a debian 5.0.9 (linux 2.6.26) after git cloning git://git.osmocom.org/libtelnet.git my autotools versions : autoconf 2.61-8 + automake 1:1.10.1-3 after running into the following autotools build #autoreconf; automake --add-missing; autoreconf; autoconf; automake; ./configure --prefix=/usr/local; make -j 2; make install I ran into that error "ltmain.sh: No such file or directory" and used the following command to fix that config error #libtoolize in the libtelnet directory and I had the ipaccess-telnet tool build/installed 2/use of ipaccess-telnet on the nanoBTS once ipaccess-telnet is installed, one should first allow the telnet on port 3210 on the nanobts using that command #ipaccess-config -n 0x400/0x400 BTS_IP which set the correct mask on the flag enabling the telnet on port 3210. Then I could telnet the nanoBTS on port 3210 w/ the following command #ipaccess-telnet <ip> 3210 once on the CLI interface for the nanoBTS, you can get help w/ >help config (...) db::setnetmask <net mask> Sets nBTS IP Net Mask db::setipaddr <ipaddr> Sets nBTS IP address (...) db::getflags (...) db::setflag <flag> Enables Config Flag db::clearflag <flag> Disables Config Flag (...) >dhcp help Expecting 3 arguments DHCP configuration flags in database: - DHCP enabled: TRUE - static IP Address: TRUE - static IP gateway config: FALSE - static VSI config: FALSE DHCP configuration flags in use: - DHCP enabled: TRUE - static IP Address: TRUE - static IP gateway config: FALSE - static VSI config: FALSE DHCP uptime = 52567 seconds DHCP state: BOUND T1 inactive T2 inactive Lease Timer inactive and the static ip configuration : To set-up the IP address >db::setipaddr IP >db::setnetmask netmask To disable the DHCP client >dhcp dhcp false >db::clearflag dhcp Xavier Carcelle

A-bis OML and OM2000 dissectors in wireshark mainline
by Harald Welte 06 Feb '12

06 Feb '12

Hi all, wireshark has merged all pending patches that we were working on. This means that the daily builds from https://www.wireshark.org/download/automated/osx/ and https://www.wireshark.org/download/automated/win32/ will now work out-of-the-box for any pcap traces of OML (Siemens and ip.access BTS) and OM2000 (Ericsson BTS). The ip.access vendor-specific RSL extensions have also been merged. By the way: If anyone was interested in writing a dissector for the Nokia OML dialect, it would be much appreciated. So far, nobody has started, but the OpenBSC code base contains an implementation of the protocol, and the hardware seems to be used by a number of project members, so getting traces should also not be a problem.

Racal 6113 For Sale
by Caleb Pal 25 Jan '12

25 Jan '12

All, I have a Racal/Aeroflex 6113 for sale. As most of you probably know, this is a GSM test set capable of initializing and running certain BTS over an ABIS link. It has a few handy features such as a power meter, etc. The unit is out of cal. I have used it to run measurements on an Ericsson RBS 2401, which is also available. Comes with power cord and a memory card for storing test sequences and test results. The unit is well loaded with options, as seen below. To my knowledge all functions of this unit work. Asking price is $1500 USD + shipping. I am willing to ship overseas, BUT, it is the buyers responsibility to complete all import/export paperwork needed. Be advised it is a rather heavy unit, so shipping OCONUS will be more expensive. Any questions please feel free to contact me off list at cleb(a)defcon-3.net. Options: Software Options: 003 PCS1900 008 GSM850 220 Ericsson 235 Siemens 250 Nortel 270 Nokia 285 interWAVE 300 AIME 310 BOSS BTS Rx Measurements 315 AMR for AIME 316 AIME AMR DTX output 319 AMR AIME error forcing Hardware Options: 04F Frequency Standard A-bis Half Rate/32K Signalling 051 A-bis T1 Interface 054 BOSS RF Module 016 Extended BBP Board 008 GSM850/PCS1900 RXTX Module 010 Encryption A5/1, A5/2 Regards, Caleb

openbsc no sound
by admin＠manateeshome.com 24 Jan '12

24 Jan '12

hello, I updated my openbsc to newest git version. and since then I do not get any sounds. The setup was working just fine before. So I presume that the problem is within openbsc <000b> osmo_msc.c:72 Assignment complete should not have been reached. <000b> bsc_api.c:331 Sending ChanModify for speech 0 1 <000b> bsc_api.c:118 Using non speech mode: 0 I think this causes the problem. But I have not changed any configuration files or anything. Can somebody tell me how to fix it? I am using a 1900mhz edge nanobts
