PPLICATIONS
The primary application of the HiGain Fractional System is to provide a quick
and cost-effective way of delivering FT1 High Capacity Digital Service
(HCDS) to customers over a metallic cable pair. The HiGain system can be
deployed on one unconditioned, non-loaded wire pair without repeaters, and
without the need for either bridged tap removal or binder group separation of
other pairs providing FT1 services.
The general guidelines, on which the CSA deployments rules are based,
require that the HDSL HiGain loop have less than 35 dB of loss at the 2B1Q
line rate of 196 kHz, at 135
Ω
source and load impedances.
The HiGain system operates with any number of other T1, POTS, Digital
Data Service (DDS) or other HiGain Systems sharing the same cable binder
group.
