I am still having one pesristent doubt. When we talk of the0 SCCP Connection oriented protocol and talk of the BSSAP messages these BSSAP messages are exchanged between what entities ? Please do claer as the SCCP Connection Oriented is really very confusing to me. Why do we need this SCCP CO protcol?? when we have the MTP routing for Circuit related sigannling & the SCCP CL for the non-circuit related signalling then where does the SCCP CO fit in between ? Somebody please
