T H2TU-C-388 L
HE
The H2TU-C-388 List 2 functions as the central office end (H2TU-C) of a repeaterless
T1 transmission system when connected to a HiGain HDSL2 remote unit (H2TU-R).
Setting new standards for interoperability and efficiency, HiGain HDSL2 modules
transmit a 1.554 Mbps T1 payload on one unconditioned copper pair over the full
Carrier Service Area (CSA) range.
