MBCCU0: No Load

historical

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
