Thanks a lot for this layer 1 debugging tutorial. It helped me a lot since i was thinking I did something wrong with mISDN. I checked the step 3 and find out that my ISDN card was working fine.
Then I tried to invert my twinax plugs and it worked. I think there is a mistake in the wiki.
It's written in http://bs11-abis.gnumonks.org/trac/wiki/BS11_Configuration :
- left Y01 PCM in (from BSC): RJ45 pin 4,5
- Y02 PCM out (to BSC): RJ45 pin 1,2
but for me it works with :
Y01 PCM : RJ45 pin 1,2 (orange / white orange for a straight cable)
Y02 PCM : RJ45 pin 4,5 (blue / white blue for a straight cable)
I can now see the network on my mobile phone thanks a lot.
Best regards

thanks a lot, andreas.
I hope this helps people debugging their physical connection, cable pin-outs,
etc.
Will that patch for the mISDN kernel driver be pushed for mainline (2.6.31)?
It might also help if we had a patch against 2.6.29 that people can apply,
rather than building from the mISDN git tree.
