Option Description
The timing reference has not been provisioned. For an NE
reference, this status appears just before the first
provisioning messages when the TCC2 is booting. Timing
is provisioned to the internal clock of the node.
The clock was locked onto a valid timing reference for
more than 140 seconds when a failure occurred. Holdover
state timing is a computation based on timing during
normal state combined with the node's internal clock. The
node holds onto this frequency until the valid reference is
restored. This status appears for NE references only.
The node is running off its internal clock without any
modification except the calibrated value to bring timing to
0 PPM. Freerun state can occur when a Force switch to the
Internal clock is initiated, when all references fail without
the 140 seconds of holdover data, or when only Internal
timing references are defined. This status appears for NE
references only.
A synchronization timing reference is not defined.
BITS-1 Out or BITS-2 Out default to this status until an
OC-N card is defined as its reference on the
Provisioning > Timing tab. This status appears for external
references only.
BITS-1 Out and BITS-2 Out use the same timing source as
the NE. This is displayed when NE Reference is selected
in the BITS-1 Out and BITS-2 Out Reference List on the
Provisioning > Timing tab.
The timing reference is locked onto one of its provisioned
references. The reference cannot be Internal or
NO SYNC STATE.
The node has switched references, but the reference is too
far away to reach NORMAL_STATE within an acceptable
amount of time. FAST_START_STATE is a fast
acquisition mode to allow the node to quickly acquire the
reference. After it achieves this goal, the node progresses
to the normal state.
The FAST_START_STATE could not acquire sufficient
timing information within the allowable amount of time.
