Page 36: Bad Splice Detection (Tscan)
SHDSL 2-Wire/4-Wire NTU Product Series Installation and Maintenance Practice Bad Splice Detection (TScan) The SHDSL 2w4w NTUs provide bad splice protection using the ADTRAN proprietary Runtime ™ TScan 2.0 splice protection feature. TScan splice detection is a non-intrusive algorithm that enables SHDSL 2w4w NTUs to detect anomalies (bad splices) in the copper pair. -
Page 37: Figure 17. Bad Splice Detection (Tscan) Menu
Troubleshooting • If more than one count register exceeds the threshold, then the count that is larger displays as a bad splice. • If two or more count register exceed the threshold and are of equal count, then the distance count closest to the unit displays as a bad splice because the detector is more accurate the closer the anomaly is to the unit. -

SHDSL 2-Wire/4-Wire NTU Product Series Installation and Maintenance Practice Restart Bad Splice Detector Screen Configuration The Restart Bad Splice Detector screen (Figure 18) enables a reset of the 24 hour count history. NOTE SHDSL 2w4w NTUs also clear the count history automatically on power-up. -
Page 39: Bad Splice Detection (Tscan) 24 Hour Counts Screen
Troubleshooting Bad Splice Detection (TSCAN) 24 Hour Counts Screen Provisioning The Bad Splice (TSCAN) 24 Hour Counts screen displays the history register. If the unit is handshaking or training, the splice loop rates and count registers do not update. If the unit is trained, it updates the splice current day data registers. But, if there was just a change in trained rate, it updates the loop rates and re-initializes to zero the current day data registers. -
