FEATURES

TScan

The ADTRAN® T200 H4TU-R incorporates the TScan™ feature. 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

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.

TROUBLESHOOTING HDSL4

This ADTRAN HDSL4 unit is equipped with troubleshooting-at-a-glance LEDs (identified on the reverse side of this document) that provide customers with a simple means of identifying the location of certain faults. Additionally, screens available via the craft interface simplify the trouble isolation process. These screens and their associated benefits are described below.

Troubleshooting Screen

Available via the Main Menu: provides ADTRAN contact information and access to the Troubleshooting Guidance and General Information screens.

Troubleshooting Guidance Screens

Available via the Troubleshooting screen: detects and displays errors and/or alarms at any of the monitored inputs (DSX1, DS1 and HDSL). Guidance on the fault(s) detected includes possible cause(s) and suggested actions, including those shown below:

DSX-1/DS1:

LOS Loss of signal (Red Alarm) at the DSX-1/DS1

receiver CLK T1 receive clock is out of range RAI Remote Alarm Indication (Yellow Alarm)

detected at DSX-1/DS1 receiver AIS Alarm Indication Signal (Blue Alarm) detected

at DSX-1/DS1 receiver ERR Errors recorded at DSX-1/DS1 receiver

General Information Screen

Available via the Troubleshooting screen: a reference page which displays the minimum acceptable signal margin, maximum attenuation, and other deployment parameters for this HDSL4 circuit.

NOTE: Along with the Troubleshooting screens, the Detailed Status screen and Performance History screen,

available via the craft access terminal, provide both real-time and historical view of this circuit. For complete deployment guidelines on the HDSL4 circuit, refer to the Installation and Maintenance

Practice referenced on the front page.

In three segment circuits (two H4Rs), individual segment resistance values must be verified. Refer to the Installa-

tion and Maintenance Practice for details and calculations.

When designing a dual H4R loop (three segment), the first segment should have lower DC resistance than the

second segment.

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.
