Page 47: Hdsl4 Features
• Fast Retrain • Splice Detection Feature The Runtime TScan splice detection feature is an ADTRAN proprietary non-intrusive algorithm for detection of anomalies (bad splices) in the copper pair. Data transmission transceivers (especially echo-cancelled technologies) are subject to performance degra- dations and errors in the presence of bad splices. -
Page 48: Splice Detection Algorithm
Appendix B HDSL2 for Verizon Installation and Maintenance Practice Splice Detection Algorithm The splice detection algorithm is designed to detect bad splices in training mode and data mode. The train- ing mode detection is important if the splice is bad enough to prevent synchronization. In data mode, the detector will run periodically after synchronization is achieved. -
