HDSL4 LOOP SPECIFICATIONS 
FOR OPTIMUM OPERATION

NOTE

: The H4TU-Cs P/N 1221401L6, 1221403L6, 1221404L6 

support only one H4R

in the HDSL4 

circuit.

HDSL4 circuit containing no H4Rs will reach up to 16 kft on the local loop (24
AWG)

HDSL4 circuit containing one H4R will reach up to 16 kft on the first segment and
15 kft on the second segment (24 AWG).

HDSL4 circuit containing two H4Rs will reach to 13.5 kft on the first segment, 14 kft
on the second segment, and 15 kft on the third segment (24 AWG). *

NOTE

: Refer to the H4TU-C or H4TU-R Installation and Maintenance Practice, Section HDSL4,

Deployment Guidelines, for other loop parameters including Insertion Loss, Pulse 
Attenuation, and Resistance Budgets for span powering

*This is one example of a circuit with 2 H4Rs.  Other loop length configurations are
possible in compliance with loop resistance restraints.  Refer to the H4R Installation
and Maintenance Practice, Section HDSL4 Deployment Guidelines, for other loop
parameters including Insertion Loss, Pulse Attenuation, and Resistance Budgets for
span powering.

UNIT RESISTANCE

Measurements are with no power applied

The H4R Tip-to-Ring resistance is approximately 6 

for each pair.

COMPLIANCE

This product complies with UL 60950, third edition.  It is intended for 
installation in restricted access locations only and in equipment with a Type “B” or
