1.9 Circuits and Timing

If the condition does not clear, replace the Slot 8 cross-connect card with an identical, spare card.

card.
Right-click the Slot 10 cross-connect card.
Step 6
Choose Reset Card and click OK. The Slot 8 cross-connect card becomes active and Slot 10 becomes

standby.
Step 8 If you have switched the Slot 8 card to active and continue to see CTNEQPT-PBWORK reported against
all I/O cards in the node, this indicates the Slot 8 card has a bad oscillator. If this is indicated, complete
the following substeps. If not, go to
a.
b.
c.
Step 9 If you then see the CTNEQPT-PBPROT condition raised against all I/O cards, verify that
CTNEQPT-PBWORK has cleared on the I/O cards. This indicates that Slot 10 has a bad oscillator. If so,
complete the following substeps:
a.
b.
c.

Replace the Slot 8 cross-connect card with a spare card. (The Slot 10 card is made active.)
Reseat the Slot 10 cross-connect card to make Slot 8 active.
Verify that the CTNEQPT-PBWORK condition has cleared on all I/O cards.
Replace the Slot 10 cross-connect card with a spare card. (Slot 10 remains standby.)
Reseat the Slot 8 cross-connect card to activate the Slot 10 card and make Slot 8 standby.
Verify that the CTNEQPT-PBPROT condition has cleared on all I/O cards.
An automatic or manual transition of a circuit from one state to another state results in one of
OOS_PARTIAL: At least one of the OC-N connections in the circuit is in OOS state and at least
one other connection in the circuit is in IS, OOS_MT, or OOS_AINS state.
OOS_MT_PARTIAL: At least one connection in the OC-N circuit is in OOS_MT state and at least
one other connection in the circuit is in IS, OOS_MT, or OOS_AINS state.
OOS_AINS_PARTIAL: At least one connection in the OC-N circuit is in the OOS_AINS state and
at least one other connection in the circuit is in IS or OOS_AINS state.
