provides the following directory functions :
a multi-protocol directory,
with interactive updates. Each update is effective
immediately. All networks known to TBT/400 are
integrated into this directory.
via the directory all network addresses,
transmission profiles used (EBCDIC or
ASCII for example).
transmission, the application program using TBT/400 need
know neither the network nor the network address
of the correspondent. TBT/400 assures
therefore the independence with the network used.
reception, the same directory serves to identify
the source of files received and eventually
to personalize the processing of them.
X25 or TCP/IP
as an optional, control the X25 address of a
caller. This provides an important enforcement
of access security.
control to applications
as an option, restrict the access, to applications
which process incoming information, to only those correspondents
formally authorized (and thus identified).
This ensures that applications that have no means of
effecting a control themselves are protected (e.g.
a translator EDIFACT, for example, cannot know
the source of a file, and consequently cannot be satisfactorily
