Field
Name
Values Description
Red Alarm Integer tally of
alarms
counted since
last reset.
The alarm condition declared when a
device receives no signal or cannot
synchronize to the signal being received. A
Red Alarm is generated if the incoming
data stream has no transitions for 176
consecutive pulse positions.
Blue Alarm Tally since last
reset.
Alarm signal consisting of all 1’s (including
framing bit positions) which indicates
disconnection or failure of attached equipment.
Loss of
Frame
Alignment
Tally since last
reset.
Loss of data frame synchronization.
Excessive
Zeroes
Tally since last
reset.
Displayed value will increment if
consecutive zeroes beyond a set threshold
are detected. I.e., tally increments if more
than 7 consecutive zeroes in the received
data stream are detected under B8ZS line
coding, or if 15 consecutive zeroes are
detected under AMI line coding.

The frequency of the transmit clock is less
than the frequency of the transmit system
interface working clock. A frame is
repeated.
