FEATURES

TScan

The 239 H4R incorporates the TScan™ feature, which allows for remote retrieval of circuit diagnostics and performance of advanced fault location. For more information, refer to the Installation and Maintenance practice.

Fast Retrain

Fast Retrain is an ADTRAN-proprietary feature that minimizes downtime due to an intermittent impairment (bad splice, noise burst, etc.).

When such impairments occur after achieving HDSL synchronization, Fast Retrain is invoked to restore service within 5 to 7 seconds. This short retrain time allows for reduced downtime compared to the traditional 25 to 30 second retrain duration.

NOTE: For proper functionality, install Fast Retrain capable units on both ends of the circuit. Failure

of a Fast Retrain attempt initiates the traditional (25-30 second) retrain.

Warranty: ADTRAN will replace or repair this product within the warranty period if it does not meet its published specifications or fails while in service.

Warranty information can be found online at www.adtran.com/warranty

Fault Bridging

The Fault Bridging feature minimizes downtime due to intermittent impairments that appear on the cable pair, for example, from a Ground Fault Interrupt (GFI), short, micro-interruption, bad splice, or noise burst. This feature allows the DSL transceivers to maintain synchronization during an interruption, thus avoiding a 25 to 30-second retrain. Depending on the type of impairment, interruptions up to 200 ms can be bridged.

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 that can potentially impact service.

Poor cable splices are often undetected by normal testing methods. Often, these splices present no problem for the data transmission equipment until oxidation with the splice itself causes a rapid impedance change, which can cause errors, signal margin fluctuation, and retrain of the DSL transceivers. The splice detection feature is accessed from the Troubleshooting Screen through the craft access port.
