Description
This command displays synchronous interface timing operational information.
Output System Timing Output —
The following table describes sync-if-timing output fields.
Label Description
System Status CPM
A/B
Indicates the present status of the synchronous timing equipment subsystem
(SETS).
Not Present — Only shown on systems without central clocks (7750 SR-1 and
7450 ESS-1)
Master Freerun — The clock is in free-run because it hasn’t had a qualified
input reference to lock to
Master Holdover — The clock was locked to an input reference but has lost all
qualified input references and is in holdover.
Master Locked — The clock is locked to an input reference
Acquiring — The clock is training to a qualified input reference.
Reference Input
Mode
Revertive —
Indicates that for a re-validated or a newly validated refer-
ence source which has a higher priority than the currently selected reference
has reverted to the new reference source.
Non-revertive —
The clock cannot revert to a higher priority clock if
the current clock goes offline.
Quality Level
Selection
Indicates whether the ql-selection command has been enabled or disabled. If
this command is enabled, then the reference is selected first using the QL
value, then by the priority reference order. If this command is not enabled,
then the reference is selected by the priority reference order.
Reference
Selected
Indicates which reference has been selected:
• ref1, ref2 - (for all chassis)
System Quality
Level
Indicates the quality level being generated by the system clock.
Current Frequency
Offset
(value) —
The frequency offset of the currently selected timing reference
in parts per million.
Reference Order
ref1, ref2 —
Indicates that the priority order of the timing references.
Reference Mate CPM
Data within this block represents the status of the timing reference provided
by the Mate CPM. This will be the BITS input from the standby CPM.
