FEATURES  
TScan  
LOC  
The ADTRAN® T200 H4TU-R incorporates the TScanfeature. TScan allows for remote  
retrieval of circuit diagnostics and performs advanced fault location. For more information about  
TScan refer to the Installation and Maintenance practice.

Bad Splice Detection  
DS1 MONITOR JACKS  
TX DS1 signal from the DCP toward network (nonintrusive)  
RX DS1 receive from the local loop (nonintrusive)  
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.

This specific unit is intended for Local Power Only. If a Span Powered unit is required, refer to  
P/N 1223426L2.  
A local power supply is available from ADTRAN by ordering P/N 1353.DSK48V04.

COMPLIANCE  
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.  
This product is intended to be installed in Restricted Access Areas only and in equipment with  
a Type “B” or “E” enclosure.  
Code  
Input  
Output  
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.
