Descriptions and Error Codes
Always investigate tests in the order presented in the following table when
inspecting errors in the system. For example, by clearing error codes associated
with the Stratum-3 Clock Alarm Query test (#649), you may also clear errors
generated from other tests in the testing sequence.
The test synchronization command also runs the Test Synchronization test
(#417). Test 417 is described in
‘‘SYNC (Port-Network Synchronization)’’ on page
Stratum-3 Clock Alarm Query (#649)
This test queries the Stratum-3 clock for its alarm status and reports the results of
the query. The Stratum-3 clock provides the system with the following six alarm
indications via the TN780 Tone-Clock circuit pack:
■
Reference A failed or CI card A failed.
■
Reference B failed or CI card B failed.
■
One power supply failed.
■
Every power supply failed.
■
One clock unit failed.
■
Every clock unit failed.
!
CAUTION:
The removal of a card in the Stratum-3 clock may cause alarm(s) to be
resolved and the query test to pass. However, the removed cards should
still be replaced to restore the Stratum-3 clock to full service.
