Jitter Attenuated Clock Slow. If
one it indicates that the dejittered
clock period is increased by 1/16 UI.
If zero the clock is at normal speed.
Jitter Attenuated Clock Fast. If
one it indicates that the dejittered
clock period is decreased by 1/16
UI. If zero the clock is at normal
speed.
Jitter Attenuator FIFO Empty. If
one it indicates that the JA FIFO is
empty.
Jitter Attenuator FIFO with 4 Full
Locations. If one it indicates that
the JA FIFO has at least 4 full
locations.
Jitter Attenuator Center Full. If
one it indicates that the JA FIFO is
at least half full.
Jitter Attenuator FIFO with 4
Empty
indicates that the JA FIFO has at
most 4 empty locations.
Jitter Attenuator FIFO Full. If one
it indicates that the JA FIFO is full.

least significant bit of a counter
that indicates the number of one
eighth bit times there are between
the ST-BUS frame pulse and
receive frame pulse (RxFP).The
accuracy of the this measurement
is approximately + 1/16 (one
sixteenth) of a bit.

Long Loop. This bit is one when
the line signal has an amplitude so
attenuated as to require substantial
equalization for data recovery.
Medium Loop. This bit is one when
the line signal has an amplitude so
attenuated as to require some
equalization for data recovery.
Short Loop. This bit is one when
the line signal has an amplitude with
minimal attenuation.
LIU Loss of Signal Indication.
This bit will be one when the
received signal amplitude is more
than 20 dB below the nominal value
for a period of at least 1 msec. This
bit will be zero for normal operation.
