HE
The H2TU-R-402 List 7A (H2TU-R) functions as the remote end of a repeaterless T1
transmission system when connected to a HiGain
line unit (H2TU-C). 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.

To ensure proper operation, the H2TU-R-402-L7A requires
either the LPS-H2C-L7A, H2TU-C-231-L7A,
H2TU-C-319-L7A, or H2TU-C-388-L7A to be used as the
corresponding line unit.
