I'm sorry to hear that :(

It looks just right, though. OML and RSL are bootstrapped. can you start it
with -dDMI:DRSL:DNM to see if it actually ever receives something back from the
BS-11? You should see something like 'E1 RX:' lines

good!

sad.

This is not broken, it is just an option. The second TRX does not interfere
in any way in the communication of the OML and RSL-first-TRX bringup, since OML
never tells the TRX1 on which TEI/TS to talk to us.
I have BS-11 with both TRX enabled without any problem here.

yes, this is a known [to me] bug. Maybe Dieter can check his LMT traces and
see what I am doing wrong when sending the DELETE OBJECT command to the BS-11.

the configuration seems correct, it is set to the right Timeslot / TEI and thus
OML should come up. Since the TEI is established between BS-11 site manager
and OpenBSC, the problems must happen at a much higher/later level. All other
parameters (such as RSL TEI/timeslot are configured over that OML link).
I'm currently also out of further suggestions. the mISDN_send problems sound
like a software issue on the PC within or above mISDN. I think everything on
layer1 + TEI works just right.
