Thank you for the quick response and also the clarification. Let me try explain again, my device is a multimode device BTS NodeB and eNodeB 2G + 3G + 4G and uses SCTP protocol for BSC RNC and MME connection, i am using different software for all the other entities and all support SCTP, but i couldn't get OpenBSC to work with abis over sctp. So my final question is: How to handle Abis over SCTP with OpenBSC.

Hi Borjan,

you seem to be confusing different technologies. A BTS is a 2G devices,
which is specified to implement Abis (RSL + OML) to a BSC. Abis, including
some vendor-specific dialects are implemented in OsmoNITB (deprecated) and
OsmoBSC.

Your subject line indicates "IuB". This is the protocol of a 3G NodeB to
a RNC, and has nothing to do with Abis. We don't implement it.

Please clarify which exact equipment you would want to use, as well as as
much information about the protocol as you have.
