4.2 H1 Layer 4 program interface
4.2.1 General information on the H1 program interface
The H1 program interface provides direct access to the functions of level 4 A of the ISO 7-layer
model.
Data is transferred in its present form, i.e. no further conversion takes place.
To access any station it is necessary to first establish a connection to the destination system. This
connection may then be used to transfer the data to and from the destination system.
It is possible to establish multiple connections to different systems or to a single system.
Any connection that is no longer required should be terminated.
