• FT–TD—Performs an FTP conversion between FTAM and FTP. The FT–TD gateway entity includes
an FTAM responder (server) and an FTP client, allowing FTAM initiators (clients) to store, retrieve,
or delete files from an FTP server. The FT–TD gateway is unidirectional and is driven by the FTAM
initiator. The FT–TD FTAM responder exchanges messages with the FTAM initiator over the full
OSI stack. Figure 13-25 shows the FT–TD protocol flow.
