No/Invalid data generated.
10/01 Fail, or parity error,
invalid idle cell.
Port shut down on receipt of first bad idle cell
until condition is fixed, as port failure is sent back
to source of data by the lack of BP indication.
No BP_ACK_OUT generation.
Loss of lock on special
coding on BP_ACK_IN.
Port shut down until the condition is fixed.
QSE Chip Failures
Multicast handling.
Cell loss or generation.
Detection possible using marked cell count.
MC Cell pool buffer.
Parity error in header or
cell.
Only detection in header, not in payload.
Partial cell buffers.
Parity error in header and
cell.
Parity error.
Multicast and Unicast selection
networks.
Cell gets out on wrong
port, cell duplicated, cell
lost.
Cell to wrong port may be noticed by receiving QRT,
if that VC is not active. cell duplication and cell loss
detection possible using marked cell count.
Arbiter.
Cell lost.
Detection possible using marked cell count.
