FAULT
HANDLING
When
an
IP
process
encounters
a
process-level
fault,
it
is
autanatically
sent
to
a 432
fault
port
to
await
service.
A
fault
handling
432
process
is
designated
to
service
the
faulted
processes
waiting
at
the
fault
port.
By
design,
IPs
and
GOPs
share
a
cormnon
base
architecture,
so
IP
faults
may
often
be
handled
by
software
similar
to
that
used
to
service
GOP
faults.
In
cases
where
unique
IP
attention
is
required,
a
special
fault
fJOrt must be
constructed
to
which
faul
ted
IP
processes
may
be
selecti
vel
y
re-sent
and
then
serviced
by
AP
and/or
GOP
software.
