f. The Aux Data for this error is not meaningful. The 1793 errors are in-line
errors that indicate a possible problem with the interface between the
Switch Control and the processor. 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 1793
errors are occurring at a high rate (more than 10 in the last hour), the
Network Control circuit pack should be replaced at the customer’s
convenience.
g. This error indicates bad clock detection circuitry on the Netcon circuit
pack. Replace the Netcon circuit pack according to the control carrier
circuit pack replacement procedures.
