 Frame Delimiters
The Frame Delimiter is an Ordered Sets that immediately precedes or follows a frame
context, and consists of the SOF (Start of Frame) and the EOF (End of Frame).
 SOF (Start of Frame)
The SOF delimiter is an Ordered Set that immediately precedes the context of a frame.
There are following SOF delimiters, shown in the Table D.3, based on the service class,
etc.
Table D.3 SOF Delimiters
No. Name Meaning Remarks
1 SOFc1 A frame delimiter to be used to require the exclusive connection of the
Class 1 service.
Since the subsystem does not support the Class 1 service yet, it
responds with R_RJT (Class not Supported) as to the frame.
2 SOFi1 A frame delimiter to be used when starting the sequence following the
exclusive connection of the Class 1 service.
Since the subsystem does not support the Class 1 service yet, it
responds with R_RJT (Class not Supported) as to the frame.
3 SOFi2 This is used for the first frame that starts the sequence of the Class 2
service.
Since the subsystem does not support the Class 2 service yet, it
responds with R_RJT (Class not Supported) as to the frame.
4 SOFi3 This is used for the first frame that starts the sequence of the Class 3
service.
5 SOFn1 This is used for frames other than the first frame of the sequence of the
Class 1 service.
Since the subsystem does not support the Class 1 service yet, it
responds with R_RJT (Class not Supported) as to the frame.
6 SOFn2 This is used for frames other than the first frame of the sequence of the
Class 2 service.
Since the subsystem does not support the Class 2 service yet, it
responds with R_RJT (Class not Supported) as to the frame.
7 SOFn3 This is used for frames other than the first frame of the sequence of the
Class 3 service.
 EOF (End of Frame)
The EOF delimiter is an Ordered Set that immediately follows the context of a frame.
There are following EOF delimiters, shown in the Table D.4, based on the service class,
etc.
