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

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

Hello Dieter,

You did turn the power off for a restart, just to be 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?

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.

Regards,
