The H2TU-R-402 List 7F (H2TU-R) functions as the remote end of a repeaterless T1
transmission system when connected to a HiGain
®
Soneplex
HDSL2 line unit (H2TU-C). Setting new standards for interoperability and
efficiency, HDSL2 modules transmit 1.544 Mbps T1 payload on one unconditioned
copper pair over the full Carrier Service Area (CSA) range.
