HDSL4 TROUBLESHOOTING GUIDE PRICING AND AVAILABILITY 800.827.0807 TECHNICAL SUPPORT 800.726.8663 RETURN FOR REPAIR 256.963.8722 61222404L1-22D PRICING AND AVAILABILITY 800.827.0807 TECHNICAL SUPPORT 800.726.8663 RETURN FOR REPAIR 256.963.8722 61222404L1-22D ADTRAN HDSL4 equipment is designed with troubleshooting-at-a-glance features. The following information provides suggestions for troubleshooting as a result of LED indications which are indicative of loop trouble. NOTE: Pressing “ESC” while on any screen will go back to the previous screen. INDICATIONS AND POSSIBLE CAUSES DSL LED Red Connect a terminal or PC to the RS-232 (DB-9) craft interface on the front panel. The terminal must be VT100 or compatible and set for 1.2 to 19.2 kbps, 8 data bits, no parity, 1 stop bit, no flow control. Select “3” from the ADTRAN HDSL4 Main Menu screen and “1” from the Span Status Screen. Verify the following conditions on the HDSL4 and T1 Detailed Status Screen: Margin . 3 dB ¦ Attenuation . 35 dB (1st segment) Attenuation . 31 dB (2nd segment) ¦ No ES, SES, or UAS (Performance History Screen, Main Menu Selection 5) If the above conditions do exist, the circuit should provide quality service; however, if any of the above conditions do not exist, a cable problem or excessive loss situation is probable, and more detailed cable testing should be done to verify all HDSL4 loop specifications are met. These conditions may also reflect intermittent cable faults or excessive noise impairments. If intermittent faults or noise impairments are suspected, review the Performance History Screen. NOTE: The insertion loss reading shown on the Detailed Status Screen is an...
