The timing facility is a building integrated timing supply
(BITS) clock attached to the node's BITS-1 pins.
The timing facility is a BITS clock attached to the node's
BITS-2 pins.
If the node is set to line timing, this is the STM-M or E1
port provisioned as the timing reference.
The node is using its internal clock.
The timing reference is in service.
The timing reference is out of service.
The reference is valid to use as a timing reference.
Out of bounds; the reference is not valid and cannot be
used as a timing reference, for example, a BITS clock is
disconnected.
Loss of signal; the reference is valid on a E1, STM1, or
STM4 facility used for timing.
—
