I tried to short the left and to invert the twinax plug (thus pluging them as in the wiki) and it works too. Then it could be a mistake in the jumper plan of BN1E1 cause they say that the left is "TE" and not "NT". Anyone else dealing with a BN1E1 card to confirm?

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 think that depends on the jumper configuration of your E1 card. Did you really put the jumpers in "NT Mode" configuration?
Yes I put NT Mode following the jumper plan (short pins on the right). My card is a Beronet BN1E1. I will try to short pins on the left and let you know if working as in wiki.
I can now see the network on my mobile phone thanks a lot.
great!
