High Speed
Ring Byte Overview
68P81092E08-O 3/19/94-UP
The
High
Speed
Ring (HSR)
data word is
a
window into the station that can be
used to help diagnose problems, monitor the status of the station, and
verify
station operation. The
HSR
data
word is circulated between
the modules of the
control tray.
This
data
word is broken down into five
data bytes. Refer
to
Chapter
2
-
Operation for information on how to
view
the data bytes
in
the Status
display.
Each of
these data
bytes may
be
viewed on
the
Status
display through
the use
of
the front
panel
controls.
The byte being monitored is displayed in
the left-most
digit
on the Status display. The
set
bits for each data byte is represented
as a
hexadecimal number
in
the
two right-most digits of
the Status
display.
Figure A-1 illustrates how
the data bytes are presented in the Status display. Table
A-1 may
be used as a
quick
reference for
converting
the data bytes displayed from
hexadecimal to binary. Tables
A-2
through
A-6
define each of the read-only
HSR
data bytes. This table is used to decode the data bytes from hex to
binary
to
help
determine the active data signals.
