This error indicates that the Tone-Clock circuit pack in the master port
network is not a TN780. If duplicate Tone-Clock circuit packs exist in the
master port network, this error may mean that one or both Tone-Clock
circuit packs are not TN780s. Verify that the Tone-Clock(s) in the master
port network are TN780s.

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:
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.
■
All power supplies failed.
■
One clock unit failed.
■
All clock unit(s) 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.
