The OAM AM solution uses the CrossTalk™ Mediation Services framework to establish a CORBA connection to the OAM 3GPP CORBA interface. The OAM AM provides mapping of events to TeMIP OSI alarms and clear correlation of these events. The solution provides automated resynchronisation between the OAM platform and TeMIP in situations where CORBA-based communications between TeMIP and OAM are established. Loss of communications between Mediation Services and the OAM CORBA communications process will also result in automatic resynchronisation when communications are re-established.
