GboFR under SGSN ATCA platform

[nacerdn2]

Hi NSN PS expert;

I need support and feedback from packet core expert, we swap recently the GboFR link from SGSN DX to ATCA, we have strange behavior, sudenly all Gb link under the same FRIU become down, by checking the ET, there status are OK but NSVCI down.

the pb can be solved only by FRIU restart, this workaround cannot be executed anytime because we'll impact other BSC connected to the same FRIU.

please need experience from expert who has experience this issue and who has GboFR under SGSN ATCA
