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.

WARRANTY

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.
