Overview
HDSL4 S
HELF
The LPS-H4TU-C is designed to mount in the LEC or Broadband chassis. For a list of compatible doublers (see
Table 1).

ODULE
The LPS-H4TU-C module is only compatible with the H4TU-R-402-5A remote module and the H4D-409-L2
doubler units. Refer to the H4D installation document LTPS-QI-1120-xx for more information on doubler
operational procedures.

PPLICATIONS
HDSL4 systems provide a cost-effective, easy-to-deploy method for delivering T1 High Capacity Digital Service
(HCDS) over two pair of wires. HDSL4 systems support a multitude of network connections.
•
The service is deployed over two unconditioned, non-loaded copper pair at 784 kps per loop.
•
Conventional, inline DS1 repeaters are no longer required.
•
Cable pair conditioning, pair separation, and bridged tap removal are not required.
For Span 1, each loop has no more than 47 dB of loss at 196 kHz, with driving and terminating impedances of
135Ω; for Span 2 and Span 3, each loop has no more than 43 dB of loss at 196 kHz. In general, HDSL4 systems:
•
Operate effectively in the same cable binder group with other HDSL4 lines, HDSL, T1, 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.
