Notes:
a. This error may not cause a Switch Control alarm if Error Type 769 is also
present since this error may actually be caused by the loss of clock
signals and not by a Switch Control failure.
b. The 257 errors are reported to the processor by the Switch Control and
indicate possible hardware problems on the Processor circuit pack. The
receipt of these errors causes Switch Control maintenance to run specific
Switch Control tests. If there really is a problem, the Switch Control tests
usually causes other errors to be logged. In the rare case where no other
errors are logged but 257 errors are occurring at a high rate (more than 10
in the last hour), the Processor circuit pack should be replaced at the
customer’s convenience.
c. If the Aux Data is less than 100, the test may have been interrupted by
LMM operations. Wait 1 minute, then test again. Retry the test a maximum
of 3 times. If the Aux Data is more than 100 or fails two out of three times
with Aux Data less than 100, the Processor circuit pack needs to be
replaced.
d. A 769 error occurs when the Switch Control reports a loss of timing signals
to the processor. When this error is present, the Switch Control is usually
not alarmed since any Switch Control test failures are really the result of
