Sonny Lafuente sonny.lafuente at entropysolution.comHi Community, Happy New Year! Would like to ask if anyone here have experience integrating OsmoBSC to Nokia MSC? Currently we are doing the integration in Nokia MSC and we encountered issue. Basically, in the SCCP part, the BSC is trying to send UDT (BSSAP) Reset but no response from the MSC. After the default timer of the RESET, we observed a SACK SST and SACK UDTS. In the SACK SST, we saw the trace that there is no Calling indicator which is my BSC point code. When checking the trace we saw this Affected Subsystem Number: 254. I’ve red some documentations in OSMO but I don’t find any SCCP management configuration in OSMO so I think this one is on MSC side. Below is the Trace we captured. BSC Point code - 2262 Nokia Point code - 7039 Regards, Sonny -------------- next part -------------- An HTML attachment was scrubbed...
