SNC-BD (Switch Node Clock Circuit Pack)
Issue 1 June 2005 2007
System Technician-Demanded Tests:
Descriptions and Error Codes
Investigate tests in the order presented below. Clearing error codes associated with the one test
may also clear errors generated from other tests in the sequence.
Note:
Note: Test #983 is not an actual demand maintenance test. This test number is used to
report the results of clear firmware-counters. Refer to error codes for Test
#777.
Configuration Audit (#759)
This test is nondestructive.
This test is run using test board short or test board long for SNC circuit packs. For
SNC circuit packs, this test queries the SNC for SNCs and SNIs in the same switch node carrier
that the SNC can communicate with and compares this data to the administered data. Failures
of this test cause entries in the error and alarm logs against Switch Node Configuration
(SN-CONF) with the board location of the SNC.
