The HiGain
®
 product family from ADC
®
 is the industry’s first practical implementations of High- bit-rate Digital 
Subscriber Line 2 (HDSL2). ADC products are fully compliant with the HDSL2 standard. 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 uses the industry’s first HDSL2 chipset (ANSI T1/E1.4 compliant) developed by ADC.
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 American Wire Gauge (AWG) wire 
or 9,000 feet of 26 AWG wire, including bridged taps.
