Field Name
Mode of Operation
Description
[Primary Stratum
Mode]
Default: Holdover
Range: N/A
Format: Predefined
Indicates the current mode of operation for the pri-
mary Stratum 3–4 module.
Holdover
Indicates that the primary module has lost its syn-
chronization source because of excessive frequency
offset and that the Holdover timing mode is main-
taining chassis timing.
Freerun
Indicates that the primary module is operating from
the internal clock source either by design or
because the Holdover timing mode has excessive
frequency offset.
Synchronized3
Indicates the module clock circuitry is locked to a
Stratum3 level of precision.
Synchronized4
Indicates the module clock circuitry is locked to a
Stratum4 level of precision.
CardRemoved
Indicates that the primary Stratum 3–4 module is
not present.
[Backup Stratum
Mode]
Default: Holdover
Range: N/A
Format: Predefined
Indicates the current mode of operation for the
backup Stratum 3–4 module.
Holdover
Indicates that the backup module has lost its syn-
chronization source because of excessive frequency
offset and that the Holdover timing mode is main-
taining chassis timing.
Freerun
Indicates that the backup module is operating from
the internal clock source either by design or
because the Holdover timing mode has reached
excessive frequency offset.
Synchronized3
Indicates the module clock circuitry is locked to a
Stratum3 level of precision.
Synchronized4
Indicates the module clock circuitry is locked to a
Stratum4 level of precision.
CardRemoved
Indicates that the backup Stratum 3–4 module is
not present.
