HDSL2 for General Distribution
PRODUCT DESCRIPTION
The HDSL2 modules referenced in this document are used to deploy a T1 circuit using 2-wire
metallic facilities.
HDSL2 provides extended range to DS1/T1 transport while providing spectral compatibility
with ADSL and other transport technologies. The ADTRAN HDSL2 Transceiver Unit for
Central Office (H2TU-C) works in conjunction with the ADTRAN HDSL2 Transceiver Remote
Unit (H2TU-R) to provide a DS1 service up to 12,000 feet on the local loop.
The H2TU-C receives DSX-1 signals, converts them and provides HDSL2 signals to the local
loop. The H2TU-R receives the HDSL2 signals from the H2TU-C and provides DS1 signals to
the customer.
Features available on these products are described in detail in "Appendix B, HDSL2 Features".
