Page 7: Introduction
HDSL4 technology provides extended range T1 (DS1) transport on the telecommunications network, and features spectral compatibility with ADSL and other transport technologies. The ADTRAN T200 HDSL4 H4R Repeater (T200 H4R, P/N 1223441L2) regenerates the HDSL4 signal, extending the range of the circuit. -
Page 8: Description
T200 HDSL4 H4R Repeater Installation and Maintenance Practice Description Up to three T200 H4R units work in conjunction with an ADTRAN H4TU-C (Central Office Transceiver) and an ADTRAN H4TU-R (Remote) to provide DS1 service on the local loop. • The HRTU-C receives DSX-1 input signals from the network through the chassis, transports them across the circuit, and terminates them through the H4TU-R. -

Page 10: Compliance
Voltages up to –200 VDC with respect to ground and between individual telecommunications conductors may be present. The T200 HDSL4 H4R Repeater is NRTL Listed to the applicable UL standards. The T200 H4R meets or exceeds all the applicable requirements of NEBS, Telcordia GR-63-CORE, and GR- 1089-CORE. - Page 11 Introduction The Chassis frame ground terminal must be connected to an earth ground to ensure that the front panel of the T200 H4R is properly grounded via the backplane connector. Per GR-1089-CORE, the T200 H4R is designed and intended for installation as part of a Common Bonding Network (CBN).

Page 15: Operational Feature Details
200 ms can be bridged. Bad Splice Detection This T200 H4R supports the Runtime TScan 2.0™ bad splice detection feature, an ADTRAN proprietary, non-intrusive algorithm for detection of anomalies (bad splices) in the copper plant. This feature monitors the cable pair during runtime for the presence of bad splices that can potentially impact service. -
Page 16: View Splice Results Screen
T200 HDSL4 H4R Repeater Installation and Maintenance Practice Splices that are varying in impedance cause the HDSL data pump to see a reduced and/or fluctuating signal quality (margin). The HDSL data pump attempts to track these changes. When the changes become too severe, errors or loss of synchronization result. -
Page 17: Fast Retrain
Operational Feature Details Fast Retrain Fast Retrain is an ADTRAN-proprietary feature that minimizes downtime when an inter- mittent, non-power related impairment (bad splice, noise burst, etc.) affects the HDSL loop and cannot be bridged. When such an impairment occurs after achieving HDSL synchronization, Fast Retrain restores service within five to seven seconds. -
Page 18: Ground Fault Or Short Detection
T200 HDSL4 H4R Repeater Installation and Maintenance Practice Ground Fault or Short Detection If a short or ground fault is detected, the T200 H4R will keep the relays open and continue to monitor the customer side interface until the fault condition clears. During the fault condition, the network-side of that repeater can function normally, allowing for synchroni- zation and loopback/sectionalization testing up to that repeater. -
Page 19: Connections
Operational Feature Details Connections All connections are through card edge connectors. Table 5 lists the card edge pin assign- ments. NOTE The T200 H4R dissipates a maximum of 5.4 watts. Ensure that the chassis ground is securely connected to the apparatus case. -
