HDSL4 for General Distribution Installation and Maintenance Practice Control Port Operation61223HDSL4L2-5C 49View Histogram ScreenThe Splice Histogram Screen (Figure 45) displays the counters that the splice detector uses tomake its result decision.Figure 45. Splice Histogram ScreenThe definitions of abbreviations shown on this screen are as follows:• Column1, labeled Splice (feet), represents the distance from the H4TU-C that the anomalydetector is evaluating.• Column 2 indicates the respective transceiver that has reported the anomaly. The L1 andL2 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 2counts.The remaining columns are for the H4R repeaters (numbered 1, 2, and 3 according to thenumber deployed in the circuit. HR1 N is the network side of the first repeater; HR1 C is thecustomer side of the repeater, and so forth.In this example, the distances shown are corresponding to an H4TU-C module since that isthe transceiver that has detected the anomaly. The count of 09 in the 650 feet row under theH4TU-C, Loop 2, column indicates that an anomaly has been seen 9 times at this distancefrom an H4TU-C module. Since 9 is larger than the count detection threshold of 8, this resultis reported to the Splice Results Screen. Since all other columns show 00 for all counts, thereis no reason to Change (C) the view of the distance column to show the distances an H4TU-Rmodule is evaluating.Reset Splice DetectorChoose Reset Splice Detector, from the Chronic Circuit Problems screen, to clear all storedSplice Detection results. A prompt displays to make sure a reset is desired. If Y (yes) is chosenthe splice detector re-initializes and starts running again.Circuit ID:HNTSVLALHDSL4 03/09/05 09:29:45Press ESC to return to previous menuHTUC L2 <- Press C to Change Distance Ref Splice Histogram ScreenSplice | H4TUC H4TUR HR1 N HR1 C HR2 N HR2 C HR3 N HR3 C(feet) | L1 L2 L1 L2 L1 L2 L1 L2 L1 L2 L1 L2 L1 L2 L1 L2------ | -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --0100 | 00 00 00 00 00 00 00 000650 | 00 09 00 00 00 00 00 001200 | 00 00 00 00 00 00 00 001750 | 00 00 00 00 00 00 00 002300 | 00 00 00 00 00 00 00 002850 | 00 00 00 00 00 00 00 003400 | 00 00 00 00 00 00 00 003950 | 00 00 00 00 00 00 00 004500 | 00 00 00 00 00 00 00 005055 | 00 00 00 00 00 00 00 005610 | 00 00 00 00 00 00 00 006165 | 00 00 00 00 00 00 00 006720 | 00 00 00 00 00 00 00 007275 | 00 00 00 00 00 00 00 007830 | 00 00 00 00 00 00 00 008385 | 00 00 00 00 00 00 00 008940 | 00 00 00 00 00 00 00 009495 | 00 00 00 00 00 00 00 00
