The HiGain HDSL2 product family is the industry's first practical implementation of
High-bit-rate Digital Subscriber Line 2 (HDSL2). When an H2TU-C-231 List 1F line
unit is used in conjunction with a HiGain HDSL2 remote unit (H2TU-R), the system
provides 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 or 9,000 feet of 26 AWG wire, including bridged taps.
