VERVIEW
The H2TU-C-231 List 1F line unit is the Central Office (CO) side of a T1 transmission system. The HiGain
HDSL2 product family is fully compliant with the HDSL2 standard ANSI T1.418-2000. Providing full-rate T1
access using just a single copper pair, HDSL2 is a cost-effective solution that offers an open architecture. The open
architecture inherent in HDSL2 guarantees interoperability allowing simple and economic accommodation of
network growth.
HiGain HDSL2 products provide 1.552 Mbps transmission on one unconditioned copper pair over the full Carrier
Service Area (CSA) range. The CSA includes loops up to 12,000 feet of 24 AWG wire or 9,000 feet of 26 AWG
wire, including bridged taps.
