View Splice Histogram Screen

The View Splice Histogram Screen
uses to make its result decision. For HDSL2, it displays six columns. The first and fourth
columns labeled
Splice (feet)
anomaly detector is evaluating. Columns 2 and 5 display the counters incremented by an
H2TU-C module when its detects an anomaly. Columns 3 and 6 display the counters incre-
mented by an H2TU-R module when its detects an anomaly.
H2TU-C and H2TU-R modules exchange this information so that the counters of each trans-
ceiver are visible locally at each end of the circuit. Since the distances that each transceiver is
evaluating may or may not be exactly the same, the Splice (feet) column reflects the distance
calculation from the displayed transceiver. To show the distances measured from the other
transceiver, press the
transceivers shown; however, the distance associated with that counter should be verified by
using the (Change) key to get the most accurate distance.
C
In the example below, the distances shown are corresponding to an H2TU-C module since that
is the transceiver that has detected the anomaly. The count of 09 in the 250 feet row under
the H2TU-C column indicates that an anomaly has been seen nine times at this distance from
an H2TU-C module. Since nine exceeds the count detection threshold of eight, this result is
reported to the Splice Result Screen. Since the H2TU-R shows 00 for all counts in columns 3
and 6, there is no reason to Change (
an H2TU-R module is evaluating.
