506.0. "VAX (V6.2, OSI V6.3): FTAM via X.25 to Siemens" by VELI::KORKKO (Veli K�rkk� @FNO, 879-5512) Sat Mar 08 1997 14:32

        I've helped customer with connection their VAX 4000-106 via X.25
        to Siemens switch. COPY/APP=FTAM works fine. However,
        DELE/APP=FTAM does not work. I do not known whether
        COPY/APP=FTAM/DELETE would work because it did not occur to me
        to test this one.
        
        My question is: do the switches generally (and specifically
        Siemens) support operations like DIR/APP=FTAM or DELE/APP=FTAM?

The answer would be "it depends" - I can tell you that at least one switch
vendor I'm aware of, charges extra for the ability to do NBS-9 files (or
DIR/AP=F).  There are other aspects to also consider.  Most times when people
use FTAM with telephone switches, it's to pull billing data from the switch (or
actually from the near-real-time storage associated with the switch); billing
data is important data and the loss of it could result in the loss of many
thousands of <insert local currency>.  The switch may protect against file
deletion.  Again, I've seen this on a switch vendor - the files could only be
deleted at the switch (so to speak).

Without looking at a trace, it's difficult to tell whether you are running into
an interoperability problem, or a restriction with the switch; and actually,
even looking at the trace it may be difficult to tell.  NBS-9 would be fairly
obvious if they negotiate away the abstract syntax needed for NBS-9.  You may
need to check with the switch vendor to see what is and is not supported. 
Though we'd be happy to take a quick look at a trace.

COPY/DELETE is probably not going to help you - since the underlying FTAM
operations are going to be the same as those used in DELETE.

506.2This switch dos not support NBS-9VELI::KORKKOVeli K�rkk� @FNO, 879-5512Tue Mar 11 1997 14:175
        The switch vendor confirmed that they do not support NBS-9
        (DIR/AP=F). I'll have to investigate the DELE/APP=F issue at
        some point.
