Choosing Reset Splice Detector option from the Chronic Circuit Problems screen
displays a prompt to ensure a reset is desired. If
Y
(yes) is chosen the splice detector re-
initializes and starts running again.
• Automatic Reset - The splice detector resets every 14 days to prevent old data from
corrupting the detector. Any problem splice listed will therefore have occurred in the last
14 days and is not leftover data. This reset will trigger an event log entry.

The Splice Histogram Screen (
) displays the counters that the splice detector uses
to make its result decision.
Figure B-4. Splice Histogram Screen
The definitions of abbreviations shown on this screen are as follows:
• The first column, 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
