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"
