Nokia packet Abis experiment

Hi OpenBSC, My company is working on integrating some BTS (Nokia Flexi ESMB) with Nokia packet Abis with OsmoBSC. The Nokia packet Abis seems to be Nokia OML/RSL over SCTP/IUA (RFC 3057). To get started, we have built a little stub that takes the incoming SCTP/IUA connection and carries out ASP_UP/ASP_ACTIVE handshake. After this handshake is complete, we see OML coming in from the BTS. It seems that this OML is in a form that would be understood by "bts_nokia_site.c". So now we would like to continue the experiment by feeding the OML/RSL into a BTS configured in OsmoBSC as type "nokia_site". Now the questions: 1. Is it possible to configure a BTS of type "nokia_site" to run Abis over a unix domain socket ? 2. Is there a better way to prototype this integration ?
