Implemented Standard
Tandem FTAM communicates with FTAM implementations on remote computer
systems by establishing associations with these remote implementations. The Tandem
FTAM initiator makes requests to remote FTAM implementations on behalf of
applications running on a Tandem system. The Tandem FTAM responder services
requests initiated by remote FTAM implementations.
You can configure your Tandem FTAM software to provide the initiator function, the
responder function, or both. Tandem FTAM Architecture
, on this page, discusses the
individual Tandem FTAM components that perform these functions and make possible
communications across the network.
Implemented Standard
For Tandem FTAM to interoperate with other FTAM implementations, it must conform
to a common subset and common interpretation of the International Organization for
Standardization (ISO) FTAM standard. See the Tandem OSI/FTAM Programming
Reference Manual and the Tandem OSI/FTAM Responder Manual for details concerning
the conformance and interoperability of Tandem FTAM. ISO 8571 is a multipart
standard; see Table i
on page xvi for references to the individual parts.
Tandem FTAM Architecture
Tandem FTAM is part of the Tandem OSI architecture, running on the Tandem NonStop
Kernel operating system, that provides the vehicle for communication between your
computer system and a remote system. Figure 1-1
on page 1-3 shows how Tandem
FTAM allows a programmer to communicate with other computer systems by means of
an application program interface (API).
The components of Tandem FTAM communicate below the Application Layer through
OSI/AS, OSI/TS, and TLAM (or PAM for G-series systems), X25AM, or TCP/IP to
perform either local-to-remote or remote-to-local file-handling activities. You configure
these components through the management interface.
The remainder of this subsection discusses in greater detail the components shown in
Figure 1-1
on page 1-3—the Tandem FTAM software, its interfaces, and OSI/AS,
OSI/TS, TLAM (or PAM), X25AM, and TCP/IP.
