HDSL4 for General Distribution
PRODUCT DESCRIPTION
The HDSL4 modules referenced in this document are used to deploy a T1 circuit using 4-wire
metallic facilities. HDSL4 provides extended range to DS1/T1 transport while providing
spectral compatibility with ADSL and other transport technologies. The ADTRAN HDSL4
Transceiver Unit for Central Office (H4TU-C) works in conjunction with the ADTRAN HDSL4
Remote Transceiver Unit (H4TU-R) to provide extended-range DS1 service on the local loop.
The H4TU-C receives DSX-1 signals, converts them, and provides HDSL4 signals to the local
loop. The H4TU-R receives the HDSL4 signals from the H4TU-C and provides DS1 signals to
the customer. Up to three H4R repeaters may be utilized to extend the service range. See
“HDSL4 Deployment Guidelines” on page 55 for details.
New features available with this product release are described in detail in “Appendix B,
HDSL4 Features” .
