ADC’s HiGain HDSL systems are used by telco providers worldwide to quickly, economically, and
reliably turn up high-speed data, voice and video services. HiGain HDSL provides transport of T1
service over two unconditioned copper pairs at distances up to 12,000 ft/3.6 km on 24 AWG
(0.5 mm) or 9,000 ft/2.7 km on 26 AWG (0.4 mm) per span (up to 5).
HiGain provides extensive diagnostic
