APPLICATIONS
HiGain HDSL2 systems provide a cost-effective, easy-to-deploy method for delivering T1 High Capacity Digital
Service (HCDS) over a single copper pair. HiGain HDSL2 systems support a multitude of network connections
and system models.
• The service is deployed over one unconditioned, non-loaded copper pair.
• 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 HDSL2 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.
