PPLICATIONS
HiGain systems provide a cost-effective, easy-to-deploy method for delivering T1 High Capacity Digital Service
(HCDS) over a single copper pair. HiGain systems support a multitude of network connections and system models
(see
Figure 1 on page
•
The service is deployed over one unconditioned, non-loaded copper pair.
•
Conventional inline T1 repeaters are no longer required.
•
Cable pair conditioning, pair separation, and bridged tap removal are not required.
In general, HiGain systems:
•
Operate effectively in the same cable binder group with other HDSL2 lines, HDSL, T1, ADSL, SDSL, POTS,
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.
