A-bis OML and OM2000 dissectors in wireshark mainline
by Harald Welte 07 Feb '12

07 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.

Issues compiling lcr on debian squeeze for OpenBSC/Asterisk stack
by Don Fanning 02 Feb '12

02 Feb '12

Hello All, I've been working on trying to get OpenBSC to work with Asterisk following this as a guide: http://openbsc.osmocom.org/trac/wiki/OpenBSC_LCR http://www.misdn.org/index.php/Howto_for_Debian Basically I'm missing the mISDN_l1loop kernel module. When trying to compile from the mISDN git repository i'm getting the following error when trying to compile (Ubuntu - 10.04 LTS ) ./configure configure: error: kernel build tree does not exist build:/lib/modules/2.6.32-33-generic/build / source:/lib/modules/2.6.32-33-generic/source (Debian - 6.06) passes configure when "make modules" is running make[3]: Entering directory `/usr/src/linux-headers-2.6.32-5-686' CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/l1oip_core.o CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/l1oip_codec.o CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/core.o CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/fsm.o CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/socket.o CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/clock.o CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/hwchannel.o /root/mISDN/standalone/drivers/isdn/mISDN/hwchannel.c: In function âmISDN_freedchannelâ: /root/mISDN/standalone/drivers/isdn/mISDN/hwchannel.c:113: error: implicit declaration of function âflush_work_syncâ make[6]: *** [/root/mISDN/standalone/drivers/isdn/mISDN/hwchannel.o] Error 1 make[5]: *** [_module_/root/mISDN/standalone/drivers/isdn/mISDN] Error 2 make[4]: *** [sub-make] Error 2 make[3]: *** [all] Error 2 make[3]: Leaving directory `/usr/src/linux-headers-2.6.32-5-686' make[2]: *** [modules_] Error 2 make[2]: Leaving directory `/root/mISDN/standalone' make[1]: *** [modules] Error 2 make[1]: Leaving directory `/root/mISDN/standalone' make: *** [modules] Error 2 root@OpenBSC:~/mISDN# I should note that Centos 5.7 and Gentoo give the same errors as Ubuntu....

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

wireshark GSMTAP
by David A. Burgess 21 Jan '12

21 Jan '12

Hello - I have been using Wireshark 1.7 from wireshark.org for GSMTAP analysis. I have seen some discrepancies that might be bugs. So I have two questions. First, is there a better-suited WS with more up-to-date GSMTAP support that I should be using (and hopefully pre-built for Mac OS X)? Second, where should I report these suspected bugs? -- David

21 Jan '12

Hello, I'm new around here and started from scratch with a new Ubuntu server. I followed the openBSC build guide on the WIKI page http://openbsc.osmocom.org/trac/wiki/Building_OpenBSC. Building libosmocore went smoothly Building libosmo-abis ended in an error: ===== checking for ORTP... no configure: error: Package requirements (ortp >= 0.13.1) were not met: No package 'ortp' found ===== Where can I find the ortp package? And secondly, is this the right version? I saw version 0.15.0 mentioned in the mail archives aready. Thanks in advance, Peter.

nanoBTS failure

20 Jan '12

Hi, I am using OpenBSC with nanoBTS 165CU and 165AU models. In normal location update BTS sends CHAN ACT NACK several times for the same ts and ss. After that it sends some failure messages and restart the trx. Here i copy the related logs from openbsc console: Thu Jan 19 15:44:03 2012 <0000> chan_alloc.c:421 (bts=0,trx=0,ts=6,ss=0) starting release sequence Thu Jan 19 15:44:03 2012 <0003> gsm_04_08_utils.c:231 Sending Channel Release: Chan: Number: 0 Type: 2 Thu Jan 19 15:44:03 2012 <0004> abis_rsl.c:579 (bts=0,trx=0,ts=6,ss=0) DEACTivate SACCH CMD Thu Jan 19 15:44:03 2012 <0004> abis_rsl.c:968 (bts=0,trx=0,ts=6,ss=0): MEAS RES for inactive channel Thu Jan 19 15:44:04 2012 <0004> abis_rsl.c:968 (bts=0,trx=0,ts=6,ss=0): MEAS RES for inactive channel Thu Jan 19 15:44:05 2012 <0004> abis_rsl.c:891 (bts=0,trx=0,ts=6,ss=0) CONNECTION FAIL: RELEASING CAUSE=0x01(Radio Link Failure) Thu Jan 19 15:44:05 2012 <0004> abis_rsl.c:621 (bts=0,trx=0,ts=6,ss=0) RF Channel Release CMD due error 1 Thu Jan 19 15:44:05 2012 <0004> abis_rsl.c:968 (bts=0,trx=0,ts=6,ss=0): MEAS RES for inactive channel Thu Jan 19 15:44:08 2012 <0004> abis_rsl.c:594 (bts=0,trx=0,ts=6,ss=0) is back in operation.

reinitialising the unit... I could not realize the reason of the problem but i think there is something wrong about the sequence of channel activation, release, ack and nack messages between openbsc and bts. Could somebody help about the solution of this or at give some idea to realize the problem? Thanks Jason
