COMPLIANCE
This product is intended for installation in restricted access locations only and in equipment
with a Type “B” or “E” enclosure.
The DSX-1 interface is intended for connection to intra-building wiring only.
This product provides span powering voltage (negative only with respect to ground, -190 VDC
nominal, GFI protection < 5 mA) and meets all requirements of Bellcore GR-1089-CORE (Class A2)
and ANSI T1.418 Issues 1 and 2.

HDSL4 TROUBLESHOOTING GUIDE
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 Yellow
Connect a terminal or PC to the RS-232 (DB-9) craft interface on faceplate. 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 Detailed HDSL4 and T1 Status Screen:
■Margin ≥6 dB
■Pulse Attenuation ≤35 dB (1st segment)
Pulse Attenuation ≤31 dB (2nd/3rd segment)
■No HDSL, ES, SES, or UAS (Performance
History Screen, Main Menu Selection 5)
If the above conditions 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 approximation that is valid for some loops.
Caution should be used when using this value.
HCRC LED Yellow
Indicates four or more HDSL4 CRC errors have occurred within the last 30 minutes. Select “5”from the HDSL4
Main Menu to review the Performance History Screen. If the DSL LED is Yellow, verify the span between the
H4TU-C and the next HDSL4 element (i.e. H4R, H4TU-R) meets HDSL4 Loop Specifications.
HDSL4 DEPLOYMENT GUIDELINES
The first segment of the circuit is defined as the section of the HDSL4 loop between the H4TU-C and the first H4R,
the second segment is between the first H4R and the second H4R (dual repeater designs) or between the H4R and
the H4TU-R (single repeater designs), and the third segment is between the second H4R and the H4TU-R.
NOTE: If dual repeaters are used in the circuit, please refer to the “HDSL4 Deployment Guidelines”section of the Installation
and Maintenance Practice for DC resistance guidelines for span powering.
■Margin ≥6 dB
■Pulse Attenuation ≤35 dB (1st segment)
Pulse Attenuation ≤31 dB (2nd/3rd segment)
■All loops are nonloaded
■Any single bridge tap is limited to 2 kft
■Total bridge tap length is limited to 2.5 kft
■Loop length up to 16 kft (24 AWG) on circuit containing no H4Rs
■Loop length up to 16 kft first segment and 15 kft second segment (24 AWG) on circuit containing one H4R
■Loop length up to 13.5 kft first segment, 14 kft second segment, 15 kft third segment (24 AWG) on circuit containing
two H4Rs
■First segment (or a circuit containing no H4Rs) Insertion Loss ≤46 dB
■Second and third segment Insertion Loss ≤42 dB
■Maximum loop resistance is 1150 Ohms for circuits without an H4R.
■Impulse Noise =50 dBrn as measured using a 50 kb filter
■Wideband Noise =31 dBrn as measured using a 50 kb filter
■Foreign Voltage DC (t-r, t-g, r-g) < 3 VDC
■Insulation Resistance (t-r, r-g, t-g) > 3.5 M
■Longitudinal Noise (Power Influence) < 80 dBrnC
