The Soneplex 220 HDSL (HLX220) module operates with ADC's
Soneplex HDSL Remote module to provide full duplex DS1
transport over two unconditioned, non-loaded copper loops up to
12,000ft. An HDSL Repeater doubles the distance up to 24,000ft.
Designed for plug-in compatibility with central office-based 220-
type repeater shelves, the HLX220 provides fast, simple and
economical HDSL transmission in new or existing installations.
