APPLICATIONS
HiGain systems provide a cost-effective, easy-to-deploy method for delivering DS1 High Capacity Digital Service
(HCDS) over a single copper pair. HiGain systems support a multitude of network connections and system
models.
• The service is deployed over one unconditioned, non-loaded copper pair.
• With HiGain, conventional, inline DS1 repeaters are no longer required.
• Cable pair conditioning, pair separation, and bridged tap removal are not required.
Each loop has no more than 35 dB of loss at 196 kHz, with driving and terminating impedances of 135
Ω. In
general, HiGain systems:
• Operate effectively in the same cable binder group with other HDSL2 lines, HDSL, DS1, ADSL, SDSL,
POTS, Digital Data Service (DDS), and other transmission schemes.
• Can be used with customers requiring DS1 service on a temporary or permanent basis.
• Provide a means of quickly deploying service in advance of fiber optic transmission systems.
DS1 is used throughout this document to refer to either the remote unit’s DS1 interface or the
line unit’s DSX-1 interface.
