FEATURES
TScan
The ADTRAN T200 H4TU-R incorporates the TScan
®
retrieval of circuit diagnostics and performs advanced fault location. For more information about
TScan refer to the Installation and Maintenance practice.
Bad Splice Detection
The Runtime TScan bad splice detection feature is an ADTRAN proprietary non-intrusive method
for detection of anomalies (bad splices) in the copper plant. This feature non-intrusively monitors
the cable pair during runtime for the presence of bad splices, which may potentially impact service.
Poor splices in the cable are often undetected by normal testing methods. Often, these splices
present no problem for the data transmission equipment until the point at which oxidation with the
splice itself causes a rapid impedance change. Such a change in impedance may cause errors,
signal margin fluctuation, and/or a retrain of the DSL transceivers. The splice detection feature is
accessed from the Troubleshooting Screen via the craft access port.
Fast Retrain
Fast Retrain is an ADTRAN proprietary feature that minimizes downtime due to an intermittent
impairment which due to its duration cannot be bridged. When such impairments occur, the fast
retrain feature will be invoked to restore service within 5 to 7 seconds, instead of the traditional 25
to 30 second retrain duration.
NOTE: Fast-Retrain capable units must be installed on both ends of the circuit for this feature
to function properly. Also, if there is a failure, for any reason, of a fast retrain attempt
then the traditional (25-30 second) retrain will be initiated.
