COMPLIANCE
WARNING: Up to –200 VDC might be present on telecommunications wiring. Ensure chassis
ground is properly connected. The DSX-1 interface is intended for connection to
intra-building wiring only.
This product is intended for installation in restricted access locations only and in equipment
with a Type “B” or “E” enclosure.
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 T1.418-2002. This product is NRTL Listed to the applicable UL standards.
POWERING MODE
The H4TU-C provides –190 VDC span powering voltage and will provide powering to the H4Rs
and the H4TU-R. The –190 VDC span powering voltage is provided on Loop 2.

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.
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
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.
1. All loops are nonloaded only
2. Any single bridged tap is limited to 2 kft.
3. Total bridged tap length is limited to 2.5 kft.
4. Bridge tap within 1000 feet of units may affect performance of the
circuit
5. Margin ≥6 dB (Detailed Status Screen)
6. No ES, SES, or UAS (Performance History Screen)
7. Foreign Voltage DC (t-r, t-g, r-g) < 3 VDC
8. Insulation Resistance (t-r, r-g, t-g) > 3.5 MΩ
9. Impulse Noise ≤–40 dBmF (measured with an F filter)
10. Wideband Noise ≤–54 dBmF
11. Longitudinal Noise (Power Influence) < 80 dBrnC OK
80–90 dBrnc Marginal
> 90 dBrnc Unacceptable
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.

NOTE: In three segment circuits (two H4Rs), individual

the Installation and Maintenance Practice
(P/N 61222404L1-5x) for those guidelines.
