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,

sure ?
Yes, of course ;)
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).
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 ;)

no, there is no change in connectors.

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

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.

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
