The H2TU-R-402 List 7G/List 7H (H2TU-R) functions as the remote end of a
repeaterless T1 transmission system when connected to a HiGain
3190, or Soneplex
powered and the H2TU-R-402 List 7H is locally powered. Setting new standards for
interoperability and efficiency, HiGain HDSL2 modules transmit 1.544 Mbps T1
payload on one unconditioned copper pair over the full Carrier Service Area (CSA)
range.
