Hi Alexander,


thank you for this information. That's very usefull.

Time is a problem because there is no much time so I have to do my best.

BTS hardware, lab environment and C programming skills aren't a problem. If I'm at the end of my knowledge there are some ery good programmers which could help me. But first I want to do it by myself.

So there are more BTS so I have to implement the A-Bis dialect for all of these BTS? It seems that you have experience with this so perhaps you can tell me where exactly I have to implement these. The only file I know to configure is the openbsc.cfg-file. When I have to implement the A-bis dialect in OpenBSC what do you mean? Which files I have to configure and what do I need to know?

In the moment we are working with a GLJ adapter (T1/E1 Analyser Hardware) for getting the traces between BTS and OpenBSC.

If you or someone else could us give tipps how to do it in the best way it would be very appreciated.


Best gerads and thank you very much for your help.
Ellen

adding support for a BTS model is not just a matter of writing a
configuration file. The details of the used A-bis dialect have to be
implemented inside of OpenBSC before it makes sense to touch a config
file.

To do that you should have:
* One of the BTSs
* A lab environment
* Protocol traces of the A-bis link during startup and usage
* C programming skills
* Time

Right now you can only use the known BTS models with OpenBSC OOTB.

I hope that helps making the situation clearer.

Kind regards,
