Summary

LED Status Indicators

DSL LED Status

Normal operation, signal quality (SNR Margin) is optimum on Loop 1/Loop 2 between H4TU-C and H4TU-R.

DS1 LED Status

DS1 signal from the CPE is present at the H4TU-R. DS1 signal from the CPE is absent at the H4TU-R.

Alarm LED Status

Alarm condition detected either locally (H4TU-R) or locally and remotely (H4TU-R and H4TU-C).

ESF/SF LED Status

Indicates received DS1 signal is unframed. Indicates received DS1 signal is SF framed. Indicates received DS1 signal is ESF framed.

B8ZS/AMI & LBK/RLB LED Status

Indicates line code (AMI/B8ZS) or loopback state (armed, local, remote).

Power and Compliance

Power Specification

This specific unit is intended for Local Power Only. Refer to P/N 1221426L1.

DS1 Monitor Jacks

TX DS1 signal from CPE toward Network (nonintrusive). RX DS1 signal from Network toward CPE (nonintrusive).

Compliance and Installation

Warning: DSX-1 interface for intra-building wiring only. Ensure chassis ground. Intended for restricted access locations.

Card Edge Pin Assignments

Options and Controls

Faceplate Buttons

Initiates bidirectional loopback of the H4TU-R toward the network and customer. Initiates a loopback at the H4TU-C toward the customer.

Troubleshooting Indications

DSL LED Yellow Indicator

Connect terminal to RS-232 craft interface. Check HDSL4 Main Menu Screen and Span Status Screen.

Possible Causes for DSL LED Yellow

Margin < 6 dB, Pulse Attenuation > 35 dB, No ES/SES/UAS, intermittent faults, or excessive noise.

Special Loopback and Control Codes

Codes like 6767 (disable span powering), 9393 (loop down HTU-C), C741/C742 (error injection).

FDL Loopback Patterns

FDL Arming/Disarm Patterns (FF48/FF24) and specific loopback codes (FF1E, FF02, FF04, FF06).

HDSL4 Deployment Guidelines
