The definitions of abbreviations shown on this screen are as follows:
• Column1, labeled Splice (feet), represents the distance from the H4TU-C that the anomaly
detector is evaluating.
• Column 2 indicates the respective transceiver that has reported the anomaly. The L1 and
L2 columns represent Loop 1 and Loop 2 of the HDSL4 circuit.
• Column 3 displays the count registered by the H4TU-R, also with Loop 1 and Loop 2
counts.
The remaining columns are for the H4R repeaters (numbered 1, 2, and 3 according to the
number deployed in the circuit. HR1 N is the network side of the first repeater; HR1 C is the
customer side of the repeater, and so forth.
In this example, the distances shown are corresponding to an H4TU-C module since that is
the transceiver that has detected the anomaly. The count of 09 in the 650 feet row under the
H4TU-C, Loop 2, column indicates that an anomaly has been seen 9 times at this distance
from an H4TU-C module. Since 9 is larger than the count detection threshold of 8, this result
is reported to the Splice Results Screen. Since all other columns show 00 for all counts, there
is no reason to Change (

Reset Splice Detector

Choose Reset Splice Detector, from the Chronic Circuit Problems screen, to clear all stored
Splice Detection results. A prompt displays to make sure a reset is desired. If
the splice detector re-initializes and starts running again.
