Encoded Mode Operation
In the encoded mode, the input data is interpreted as eight bits
of data (D
diagnostic input bit (SVS). If the context of the data is to be
normal message data, the SC/D input should be LOW, and the
data should be encoded using the valid data character set
described in
If the context of the data is to be control or protocol information,
the SC/D input is HIGH, and the data is encoded using the valid
special character set described in
and Sequences (SC/D = HIGH)[1, 2] on page
characters include all protocol characters necessary to encode
packets for Fibre Channel, ESCON, proprietary systems, and
diagnostic purposes.

The diagnostic characters and sequences available as special
characters include those for Fibre Channel link testing, as well
as codes to be used for testing system response to link errors
and timing. A Violation symbol can be explicitly sent as part of a
user data packet (i.e., send C0.7; D
1), or it can be sent in response to an external system using the
SVS input. This allows the system diagnostic logic to evaluate
the errors in an unambiguous manner, and does not require any
modification to the transmission interface to force transmission
errors for testing purposes.
