Description
===========
Siemens receives our first DT-TPDU (FTSIE-SAC) and responds to it with
a DT-TPDU (FTSIE-SOP). As however we never receive a OSI Transport AK
we initiate checkpointing at the OSI Transport level. As we never
receive an AK we therefore disconnect the Transport Connection.
Siemens has recognised the problem and are providing a REP
(Siemens-speak for Fix kit). Anyone who gets to hear of this kind of
problem please inform their customer that they should ask their
Siemens/S.N.I. representative to provide a REP to Problem # (Fehler
Meldung A0108145).
