Hallo Bjoern,
I tried it several times, and left the BTS on over night. The LMT cable wasn't always plugged in. When I boot up the BTS it always says that the second TRX has Load and the first not.
You did turn the power off for a restart, just to be sure ?
If I try to bring up the BTS with your SW under Win. I get the Abis Link Up but when I try the Load DB I get some error messages on LMT. Then the second TRX goes down to No Load.
If the firmware for the first TRX is not loaded, the Abis communication will still work because the microcontroller which takes care about the commnunication is working. The error messages result from the not working TRX (I guess it would work if TRX1 instead of TRX0 is used, however I have not tried it yet).
And this is the condition until I reboot the BTS. Maybe its a software issue?
I don't think so because the communication processor loads the same firmware in both TRX. This is done in parallel. In your trace there is the same behavior I experience here, loading the firmware for TRX0 ad TRX1 starts, however loading TRX0 stops immediately. Of course I can only speak for my BS-11, but here it is most certainly a hardware issue (at one time I could even see an error message that the first power supply unit did not start).
Best regards, Dieter
Hello Dieter,

Yes, of course ;)

The error messages result from the not working TRX (I guess it would work if TRX1 instead of TRX0 is used, however I have not tried it yet).
What do I have to do to use the second TRX instead? Plug in the other Twinax connectors? Do I need to setup the second TRX separately on LMT?
Thanks ;)

you have to hack the OpenBSC code to assume '1' is the first TRX in the BTS, rather than 0. This probably needs to be done at least in the channel allocator, as well as the c0 pointer in sturct gsm_bts
Plug in the other Twinax connectors?
no, there is no change in connectors.
Do I need to setup the second TRX separately on LMT?
according to your bs11_config mail it seems like it is correctly set up.
As for what seems to be a hardware problem: You can obviously get a different BS-11 from me, if you can take care of the transportation.
Please note I'll not be in Berlin from May 4 through May 26, so we should probably do that before I leave.

Hello,
I have tried the second TRX. During the setup of TRX1 on LMT the second also goes down to No Load.
PHASE: 3 Normal MBCCU0: No Load MBCCU1: Load Abis-link: Up
and then after setup:
PHASE: 3 Normal MBCCU0: No Load MBCCU1: No Load Abis-link: Restoring
I hope its not the BS11 that is broken. Maybe its the software?
Best regards Björn Heller

I think it is that particular BS-11, just to be safe you're not wasting time with some broken hardware here... I am still in Berlin and we can replace it this week. I'm not in Berlin from May 4 through 25.
Since you have multiple BS-11, do you see the same behavour? If yes, then I doubt it is the hardware.
Regards,
Hello Harald,
Ok, lets replace the BTS. Looks like the BTS is broken.... :(
I haven't found time yet to flash the 3 BS11 at the lab.
Tell me a time/date and I will be at the storage house. (Holzhauser)
Best regards Björn
