Why Terminator and CopperPro
together are the only proven
way to qualify HDSL
Advances in DSL (digital subscriber line)
technologies have had a dramatic impact on
the availability and deployment of broad-
band service. High-speed links carrying
voice, data and video services can be
deployed quickly over existing outside plant
copper cable. While some circuits turn up
with minimal effort, many suffer problems
from the outset.
Traditional testing methods will no longer
do the job. HDSL2 and HDSL4 don’t use
repeating signals that can be replicated with
BERT and Nyquist tests used in the past.
Instead, they use complex TCPAM
technology, which requires a different
testing procedure.
The 990DSL CopperPro and Terminator
feature automatic tests designed specifically
to address this problem. CopperPro and
Terminator prequalify pairs for HDSL2 or
HDSL4 in less than two minutes, and help
locate facilities problems that generate
errors or cause circuits to fail.
HDSL2/4 tests include:
• Foreign voltage to uncover facility damage
• Shorts and grounds to identify any short
or crossed conductors, failed insulation or
water in the cable
• Opens, capacitive length and balance,
which, along with the resistance tests,
can help determine if water, split pairs or
an unknown bridge tap is present
• Signal loss and slope in the voice band
to help detect bridge taps and other
anomalies

• Metallic noise, power influence and longi-
tudinal balance at voice band and data
frequencies to assess how well the pair
can “self-shield” itself from the effects
of noise from the environment or in
the cable
• Wideband circuit noise and level across
the entire frequency range (spectral noise)
to make sure ambient noise in the HDSLx
pass band are below acceptable levels
• Loop resistance and resistive balance and
length to assure that splices, gauge
changes or other impairments don’t com-
promise the long-term reliability of the
circuit
• Loop attenuation with pass/fail PSD
(power spectral density) masks for
upstream and downstream to assure
the performance of the TCPAM encoded
transmission.
