7.1.4.4 Message Transmission Phases
To establish which system sends and which system receives information and to ensure the
actions of sender and receiver are well coordinated, there are three distinct phases in trans-
ferring information:
Establishment Phase
Transfer Phase
Termination Phase
Figure 6: Message Transmission Phases
Within the transfer phase, all records of the corresponding message are grouped into longer
frames to increase speed. The records are separated through a [CR] character. Therefore, to
obtain pure ASTM records again, the receiver must concatenate all the frames and wait for
a [EOT] character. Finally he can process the frame and split it into different records using
the [CR] as separator.
