Hello,
I am thinking about selling my Siemens BS-11 and a compatible HFC-E1 Evaluation Board.
If anyone is interested please send me a mail: baumgrass at hotmail.com .
Regards,
Bernd.
Hi,
I wrote some code that lets me test OpenBSC without using real hardware, e.g.
one is bothered to wait for the nanoBTS to open the OML connection again, one
doesn't have the unit for the right band, one doesn't have a dual trx system,
or because reproducing the issue is difficult (RF interference, LAPDm timeouts).
I have packaged the code with OBS and right now it is only available for debian
stable (it can be installed on unstable as long as the stable feeds are inside
the sources.list).
Install:
$ echo 'deb http://download.opensuse.org/repositories/home:/zecke23/Debian_6.0/ ./' > /etc/apt/sources.list.d/
$ aptitude update; aptitude install gnu-smalltalk osmo-st-openbsc-test
(the packages are signed but the key expired two years ago, so the question
is if you want to trust Debian packages from OpenSUSE)
Using:
$ gst
st> PackageLoader fileInPackage: #FakeBTS
...
st> bts := FakeBTS.BTS new.
st> bts btsId: '1/0/0'
st> bts connect: 'localhost'; waitForBTSReady.
...
Testing:
There is the FakeBTS.OpenBSCTest class that has methods to require
channels and these Lchans can be used to send RSL messages. I don't have
a public example at this point though.
Vision:
I hope this code will be used to do nightly tests of OpenBSC, specially
the error paths (e.g. timeouts on handover, timeouts on assignment,
timeouts on channel release, etc.)
There is a branch that brings DualTRX support and I am going to merge
this to master soon. What I am missing is some test launcher code (it can be
in python or ruby if someone volunteers) that will launch osmo-bsc/osmo-nitb
with a given configuration file and initialize the HLR with a set of
given subscribers.

PS: Blog post will follow once the code has matured a bit
These are some minor modifications to make openbsc run on OSX.
You have to have these MacPorts installed:
pkgconfig
automake
autoconf
libtool
libdbi
libdbi-drivers
sqlite3
... and set:
export LDFLAGS='-L/opt/local/lib'
export CPPFLAGS='-I/opt/local/include'
Everything else should work as usual.

Hello,
I'd like to directly cable a handset to a nanoBTS and thought I could:
- put attenuators on the nanoBTS TX and RX ports
- connect the other side of each attenuator to a resistive
splitter/combiner that has 6dB loss
- connect the combiner common port to the MS
Does this sound sensible and if so what size of attenuators might I
want assuming MS and BTS were each set at 6dBm? I've seen figures for
receiver sensitivity, but wasn't sure as to a "good" RF level to use
with direct cabling!
I also have 10/20 dB directional couplers and circulators if they
might find use in a better configuration.
Regards,
Andrew

Hello,
I'm working with OpenBSC since 2 month. Currently my OpenBSC setup runs with
2 mobile phones which can communicate A5/1 encrypted with each other.
I got several problems while running this system with a NanoBTS. I use
osmo-nitb.
Entries in my HLR receive wrong time values. The time values of the column
"created" and "updated" are exactly 2 hours earlier than they should be.
The system time of the controller works fine and the time in the logs from
"./osmo-nitb -e 1 -T" is correct. Are there any other timers which work with
the NanoBTS?
Furthermore my network does not run stable. Sometimes following error occurs
:
input/ipaccess.c:454 Bad signalling Message, sign link returned error
input/ipaccess.c:260 Forcing socket shutdown with no signal link set
The error usually appears after some authentification "traffic". Sometimes
the system runs stable for several hours without any errors. The error leads
to a restart of the connection. I'm not sure if this problem has something
to do with the first problem.
thanks and best regards!
Nicklas
Hi guys,
Does anyone know if the sysmoBTS has any kind of RADUIS server? By entering the " opkg search *rad* " command i didn't get anything.
Best regards
Yann
