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. HDSL4 DEPLOYMENT GUIDELINES The guidelines provided below apply to the segments of an HDSL4 circuit, as follows: 1st segment = between the H4TU-C and H4R NOTE: The insertion loss reading shown on the Detailed Status Screen is an approximation that is valid for some loops. Exercise caution when using this value. 2nd segment = between two H4Rs or single H4R and H4TU-R 3rd segment = between the second H4R and the H4TU-R These deployment guidelines provide the basics for HDSL4 circuit provisioning. If these parameters are met, then the circuit will provide quality service. If not, a cable problem or excessive loss situation is probable. In this case, a more detailed cable analysis is required to ensure that all HDSL4 loop specifications are met. These conditions may also be the result of intermittent cable faults or intermittent noise impairments. If intermittent problems are suspected, utilize the Performance History screen to assist in troubleshooting. Range Limits: 26 Gauge / 70ºF / PIC 1. All loops are nonloaded only Recommended Maximum 2.

Refer to the HDSL4 Deployment Guidelines section of the Installation and Maintenance Practice (P/N 61222404L1-5x) for those guidelines.
