Can you tell us more about that device?

To the best of my knowledge, there is no 3GPP specification for Abis over SCTP.
As such, it's not a surprise that we're not implementing it in OsmoBSC :)
Maybe I missed something. Can you please point me to relevant
specification for this Abis dialect?
I would assume it's some vendor-specific dialect. Do you have protocol-level
documentation for that available? Do you have protocol traces of this dialect?
In any case, even with documentation and/or traces, you would need to
develop the respective code to interface this new Abis
dialect/encapsulation. The required effort depends on how far that
dialect diverges from the existing "known" dialects/formats. If it's
just 08.58 RSL and 12.21 OML inside SCTP, then it should be rather
little effort. But that's a big "if" :)
Regards,
Harald
