The OFTP Commands
To control the communication of data, OFTP provides a set of signals
which indicate when a message can be sent to the receiving system. These
signals are called the OFTP commands.
Each command serves a different function, not all of which will be used
in every transmission – the signals used will be dictated by the
nature of the communication session itself.
Files supported by the OFTP OFTP allows the transfer of different types of files. These include
fixed length records, variable length records, unformatted files and text
format files.
Access Methods and the OFTP OFTP supports TCP/IP, ISDN, direct native access to the X.25 network,
dial-up connections using a combination of recommendations X.28, X.3 and
X.29. It provides both error detection and recovery procedures for the
latter. As well, ISDN connection to X.25 networks can be used in accordance
with recommendation X.31. OFTP is perfectly adapted to ENX extranet; certified ENX operators
offer various types of connections (isolated station with IPsec customer,
connection by STN or ISDN: up to 64 kbits, small LAN, LAN...). See
