The SSCB firmware checksum,
the
SSCB Standard mode, and
the
I/O Mode
ASICs
are tested.
This includes output
latch and input buffer loopback,
MUxXbus circuitry, and
HSR
circuitry. The
SSCB
code
plug
is tested for
proper module ID, version number, and checksum. The SSCB IPCB
ports
are
tested.
If any of
these tests
fail,
the corresponding error code appears on the
Status display.
a
The audio diagnostics is performed. The Status display indicates
a
test-in-progress dash (-) during the
SSCB audio diagnostic
test.
If any of
these tests
fail,
the corresponding error code is
displayed
on the
Status
display.
The expansion
reset
is disabled.
The SSCB firmware version number displays.
a
The
TTRC
diagnostic routines
are enabled (if
a
TTRC
board is present)
with
an
IPCB wake-up command. The Status
display indicates
a
test-in-progress
dash (-)
during
the
TTRC
digital
and audio
diagnostic
tests.
All TTRC
failures are
reported at this time. When
the
TTRC
board completes the
diagnostics,
the
TTRC
firmware version number displays.
The Secure board diagnostic routines
are
enabled
(if
Cca
Secure module is
present)
with
an
IPCB wake-up
command. The Status display indicates
a
test-in-progress dash (-) during the Secure board
digital and audio
diagnostic
tests.
All
Secure failures
are
reported
at
this time. When the
Secure board completes the
diagnostics,
the
Secure board firmware version
number displays.
The normal
station operating mode is entered. The
Status display reverts
to
the
Chan/Mode/Key
indication. If several non-fatal
errors are detected
during diagnostics, they may
queue up. If
so,
they appear
on the
Status
display, in
order,
until
the error queue is emptied.
NOTE
In
the
event that multiple errors display, always
resolve the first error displayed before
trying
to
debug
other errors. Often the other failures
are the
result of
the
first failure.
Extensive audio-path diagnostic
tests are
implemented
on
all modules
to
detect
defective components and circuit blocks. This capability
enables the station to
diagnose itself and indicate which component
or
group of components is faulty.
As
a
result, users can
be
alerted
to
potential problems before they experience
them,
reducing station down time and service costs.
Typically,
the
audio
tests are
performed during
the
power-up
sequence.
After
the
digital circuits have
been
verified, audio
tests are
performed.
