Page 27: Bad Splice Detection (Tscan)
Troubleshooting Bad Splice Detection (TScan) The SHDSL 2-Wire/4-Wire LTU provides bad splice protection using the ADTRAN proprietary ™ Runtime TScan 2.0 splice protection feature. TScan splice detection is a non-intrusive algorithm that enables the SHDSL 2-Wire/4-Wire LTU to detect anomalies (bad splices) in the copper pair. -
Page 28: Figure 10. Bad Splice Detection (Tscan) Menu
SHDSL 2-Wire/4-Wire Line Terminating Unit (LTU) Installation and Maintenance Practice • 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. -
