SE_INPUT_PORT_FAIL
(14:11)
Bit 14 corresponds to port 3, bit 13 corresponds to port 2, bit 12 corresponds to port 1
and bit 11 corresponds to port 0 as follows:
1
Indicates one of the following:
No SOC or “10” pattern was present on a switch fabric port input, or
invalid cell code, or
bad idle cell code, or
fabric out of synch.
0
The switch fabric input was normal.

interrupt.
BP_REMOTE_FAIL
(10:7)
Bit 10 corresponds to port 3, bit 9 corresponds to port 2, bit 8 corresponds to port 1 and
bit 7 corresponds to port 0 as follows:
1
The forward data path from the QRT to the QSE was found to be bad
through signaling on the BP_ACK_IN(3:0) line.
0
The forward data path from the QRT to the QSE was good.

BP_ACK_FAIL
(6:3)
Bit 6 corresponds to port 3, bit 5 corresponds to port 2, bit 4 corresponds to port 1 and
bit 3 corresponds to port 0 as follows:
1
BP_ACK_IN(3:0) did not have the special code.
0
BP_ACK_IN(3:0) had the special code.
