Commits 7970ceaead78ff224390a25f416b22bcd8e4e37e..32618160bdb154ca756c783b67b131533226f7ae added a fork of titan.Protocol.Emulations.SCCP with a new N-NOTICE.req primitive which was needed in STP_Tests_TCAP to trigger transmission of a UDTS message. That primitive doesn't exist in the specs, since no user of SCCP is expected to be requesting a transmision of UDTS. Hence, this commit rewrites the test to avoid the need for such a primitive, by hooking directly into the lower layer MTP3 User SAP (M3UA or IPA) and crafting and transmitting the SCCP UDTS over there directly. Follow up commits will revert the commits adding such a N-NOTICE req to the SCCP and TCAP layers.
