downlink port board messages to the Switch Control than the Switch
Control is able to process. A WARNING alarm for this condition will
automatically be resolved if no errors of this type are detected within a 15
minute period. If no other errors are logged but 2561 errors are occurring
at a high rate (more than 10 in the last hour), follow normal escalation
procedures.
System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the table below when
inspecting errors in the system. By clearing error codes associated with the
Switch Control Reset Test
for example, you may also clear errors generated from
other tests in the testing sequence.
Switch Control Channel Interface Test (#92)
Loop-back messages are sent to the Switch Control via the interface used for
control channel messages. The messages are returned to the SPE for verification
via the same interface. The TDM bus is not involved in this test since the
messages are looped back on the MSSNET circuit pack.
