H2TU-R-402 L
The H2TU-R-402 List 4F functions as the remote end of a repeaterless T1
transmission system when connected to a HiGain
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.
