the first frame of a Sequence for Class 3 Service.
SOF Fabric (SOFf)
SOF_f:
Contains a code value of 0x28 indicating SOF Fabric. If an Nx_Port or Fx_Port receives a Class F frame,
indicated by an SOFf delimiter, it shall be discarded by the Nx_Port or Fx_Port. The receiving Nx_Port or Fx_Port may
send an R_RDY.

End of Frame (EOF)
The End-of-Frame (EOF) delimiter is an Ordered Set that immediately follows the CRC and is transmitted on a word boundary. The
EOF delimiter designates the end of the frame content and is followed by Idles. There are three categories of EOF delimiters found in
the Fiber Channel standard, however the test set only supports the first category that indicates that the frame is valid from the
sender's perspective and potentially valid from the receiver's perspective.
The following selections are available:
EOF_t:
Contains a code value of 0x42 indicating EOF Terminate. The EOFt indicates that the Sequence associated with this
SEQ_ID is complete. EOFt is used to properly close a Sequence without error.
EOF_n:
Contains a code value of 0x41 indicating EOF Normal. The EOFn identifies the end of frame when one of the other
EOF delimiters indicating valid frame content is not required.

Payload
The test set implements and observes "Methodologies for Jitter and Signal Quality Specification (MJSQ)". A major goal of MJSQ is to
improve the relationship between measurements on signals and receiver performance in terms of bit errors. The unit transmits a
"compliant pattern" which consists of a valid Fiber Channel protocol frame (SOF, payload, CRC, EOF) containing a test pattern as the
payload. Different payload selections are available depending on the Fiber Channel layer to be tested. The payload consists of 0 to
2112 bytes, and is sent in 4 byte increments, otherwise it is considered to be a misaligned frame.
