Re: OpenBSC with Dahdi+Asterisk and several BTS

Hey folks,

I think, OpenBSC works now. Here what I did and what I get:

I tried the steps from Michael and get following answer:

To test telnet:

/etc/init.d/openbsd-inetd restart

• Restarting internet superserver inetd

telnet 192.168.0.102

So thanks a lot to you all who helped me. This Mailinglist was a great support for me to install OpenBSC,

Hey Michael,

thanks. In the moment there is another problem.

Since yesterday I wasn't able to load the module zaphfc.

...

modprobe zaphfc FATAL: Error inserting zaphfc (/lib/modules/3.0.22/dahdi/zaphfc/zaphfc.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Now I'm installing Asterisk a second time and hope that it works. Then I will try your advice again and give you a answer how it works.

Wish you a nice day.

Regards Ellen

Hi Ellen,

...

I need to correct:

cd openbsc src/osmo-nitb/osmo-nitb -c doc/examples/osmo-nitb/**nanobts/openbsc.cfg -C

Then you should see the message: <0019> ipaccess.c:841 enabling ipaccess BSC mode DB: Database initialized. DB: Database prepared. <0007> sms_queue.c:232 Attempting to send 20 SMS

telnet localhost 4242

Hey Guys,

thanks a lot for your answers.

@Peter: I want to test OpenBSC without BTS because the installation has to be ready in the end of the week and in the moment there is no BTS which I can test if it works. In the end I want to connect OpenBSC with several BTS. Before OpenBSC runs with another BTS than those which are supported yet I have to build an openbsc.cfg-file. That's is what I think I should do. I don't know if there are other configurations to do. There is no way to use OpenBSC which one of the BTS which are supported now. It has to work which one other BTS.

@Michael: I installed telnet and followed your steps but I get following message:

/etc/openbsc/doc/examples# telnet localhost 4242 Trying 127.0.0.1... telnet: Unable to connect to remote host: Connection refused

As I did:

telnet localhost

I got:

I got:

I unloaded hfcmulti, mISDN_dsp, mISDN_core, started dahdi, but if I want to start OpenBSC I get:

/etc/openbsc/src/osmo-nitb# ./osmo-nitb -c openbsc.cfg <0005> bsc_init.c:512 Error enabling E1 input driver

Perhaps I did something wrong as I want to load the driver, because I have an HFC-E1 card but dmesg shows: dmesg

dahdi: Telephony Interface Registered on major 196 dahdi: Version: 2.4.1 *vzaphfc: HFC-S PCI A ISDN (V1.42) loading*

Wish you a nice day.

Best regards. Ellen

Hi Ellen,

here is how I start OpenBSC without any BTS.

cd openbsc

src/osmo-nitb -c doc/examples/osmo-nitb/__**nanobts/openbsc.cfg -C

and make sure the current directory is not write protected.

Then I start the telnet terminal with: telnet localhost 4242

Hope this helps.

   Hey folks,

   I am new with OpenBSC and want to build OpenBSC with several BTS
   from
   different types.

   At first what I need: I want to test OpenBSC without a BTS just
   to see
   if the installation worked successfully. Also I need to know
   what I have
   to do if I want to use a BTS which isn't configured yet.

   What we want to do in the end is to test the BTS with a selfmade
   programm. For this we need an interface between the hardware BTS
   and the pc.

   What I have:
   Ubuntu 11.10
   Kernel 3.0.22
   several BTS (Siemens BS60/BS240, Nokia Citytalk, Alcatel G9100
   etc...)
   HFC-E1 card from Cologne Chip
   OpenBSC
   Asterisk 1.8.4.4 + Web-GUI (Asterisk NOW 2.0)
   Dahdi 2.4.1
   Libpri 1.4
   mISDN v2.x
   mISDNuser 2.0.11
   LCR 1.7
   Twinkle, Wireshark etc.

   Why mISDN + Dahdi:
   First I tried to use mISDn + mISDNuser + LCR for a connection
   between
   OpenBSC and Asterisk. mISDN was integrated in the Kernel so I
   thought
   it's the best idea to use it. I installed mISDNuser and LCR but
   there
   are several problems. For further informations you can have a
   look here:
   http://www.ip-phone-forum.de/_**_showthread.php?t=247932<http://www.ip-phone-forum.de/__showthread.php?t=247932>

   <http://www.ip-phone-forum.de/**showthread.php?t=247932<http://www.ip-phone-forum.de/showthread.php?t=247932>

...

   Because of the problems mit LCR/chan_LCR and Asterisk I decided
   to use
   Dahdi because it's also installed since I installed Asterisk.
   Asterisks
   works fine with the softphones which I created with Twinkle and
   also the
   Asterisk GUI works without problems.

   To use Dahdi:
   modprobe -r hfcmulti
   modprobe -r mISDN_core
   /etc/init.d/dahdi restart

   /etc/dahdi/system.conf:
   dchan=1
   bchan=2-30

   openbsc.cfg:
   e1_input
   e1_line 0 driver dahdi

   To start OpenBSC:
   cd /etc/openbsc/src/osmo-nitb
   ./osmo-nitb
   Error:
   <0005> bsc_init.c:493 Failed to parse the config file:

'openbsc.cfg'

   So now I'm not sure what to do because I'm not sure what exactly

is wrong and if it could work without a BTS. There are enough informations if I want to test a BS11 or a nanoBTS but I'm a little bit lost how to work with another BTS.

   In the next day I will get the traces from the several BTS to
   build an
   interface between BTS and OpenBSC so I can build the
   openbsc.cfg-file.
   But it would be great if it is possible to test OpenBSC before I
   get the
   traces.

   To get a connection between OpenBSC and Astrisk with Dahdi is a
   problem
   which I should solve by myself. There should be enough
   information in
   the internet.

   if you have questions or need more informations just write an
   e-mail.

   Best regards and thanks in advance. It would be great if someone
   could
   help me or give me some advice what I could do.

   Ellen
