PPLICATIONS
HiGain HDSL2systems provide a cost-effective, easy-to-deploy method for delivering DS1 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.

I AIN EGENERATORS
For applications without regenerators (doublers), the H2TU-C-202 is directly connected to an H2TU-R remote
unit by one HDSL2 cable pair. The H2TU-C-202 is compatible with all HiGain H2TU-Rs.
For regenerator applications, one to two regenerators may be used in the HDSL2 loop between the H2TU-C and
H2TU-R, for instance:
• The H2TU-C-202 can power one regenerator (H2RU-407 or H2RU-409) and a remote unit (H2TU-R-402)
for a total of two spans.
•
If the H2TU-R is locally powered, the H2TU-C can power up to two regenerators for a total of three spans.
Future releases of the H2TU-C-202 List 1F will support regenerators.
