+===== Configure SCCPlite
+
+Traditionally, OsmoBSC implemented only an SCCPlite based A-interface, an
+ad-hoc standard encapsulating BSSAP in an IPA Multiplex. Since 2017, OsmoBSC
+supports primarily a proper 3GPP compliant SCCP/M3UA A-interface known as AoIP,
+by a new libosmo-sigtran implementation. In 2018, SCCPlite compatibility was
+added to libosmo-sigtran, re-enabling the option of using an SCCPlite based
+A-interface. For details, see the OsmoSTP manual, chapter "IPA / SCCPlite
+backwards compatibility".
+
+Here is an example configuration of OsmoBSC for SCCPlite, assuming the BSC at
+point-code 1.23.3 and an SCCPlite MSC listening on 127.0.0.1:5000 with own
+point-code 0.23.1:
