With higher bit rates and triple-play
services, the performance required
from DSL lines is rising dramatically.
Lines are being operated closer to their
bit rate limit while real-time voice and
video services are requiring greater
line stability. As a result, you will need
to put the right tools and processes
in place to prevent escalating OPEX,
while keeping customers happy.

Support more quality sensitive services
DSL technology has enabled you to deliver triple-play
services more cost effectively. Video and voice as well
as new multimedia services tend to become more
demanding in terms of bandwidth, latency and error
rate, making them more sensitive to the line quality.
Despite advances in DSL technology, DSL technology
does have its limits. A DSL line capable of supporting
High Speed Internet may be unable to support more
quality-sensitive services such as IPTV or VoIP. Prob-
lems may arise from the poor condition of the loop itself
(e.g., contact problems, crosstalk, interference, etc.) or
from service demands that exceed the loop’s capability.

Streamline operations and
control OPEX
The access network, with its many
ramifications and connections, is a
natural place for problems to arise.
With DSL, you will need to master
a new set of challenges in order to
avoid escalating costs. The problem,
however, is that traditional testing
systems can’t provide you with the
visibility required for DSL line qual-
ity. To streamline operations, while
maintaining control of your opera-
tional costs, you need to implement
operational best practices. This must
encompass the whole service life-cy-
cle, including: service planning and
network readiness, service provision-
ing, maintenance, troubleshooting and
customer support.
Provide better
customer support
Providing better customer sup-
port is paramount for customer
satisfaction and retention. The
quality perceived by your customers
is linked to the service quality and
degree of support they get from your
organization. That’s why, ever since
the early stages of DSL, you have
tried to bring greater visibility of the
DSL line quality to your customer
support team. You want to take the
right decisions and actions from the
very start, enabling faster and more
appropriate problem resolution.
Line testing strategies in
the evolving access network
The obsolescence of telephone
switches and the on-going demand for
higher bandwidth is also driving the
transformation of your access net-
work. This often entails the deploy-
ment of smaller remote access nodes,
which allow you to reach customers
with shorter loops. Broadband access
infrastructures are also evolving to
support telephony services by means
of various POTS or VoIP deployment
options. As the telephony switches
gradually disappear, and you begin to
deploy smaller FTTN nodes, you will
need to put in place a new line testing
strategy that adapts to your evolving
network architecture.

Pro-active line management
Pro-active management will enable
you to detect problems before they
impact your customers, or correct
problems automatically through
dynamic line reconfiguration. The
Alcatel-Lucent 5530 NA monitors
your DSL lines and detects degrada-
tion trends in line transmission
quality. Dynamic Line Manage-
ment is a further capability that
automatically rearranges line configu-
ration parameters to stabilize lines and
assure they are working at the best
performance possible. This capability
can stabilize up to 70 percent of your
problem lines, eliminating customer
frustration and operational costs.
Customer care integration
The Alcatel-Lucent 5530 NA
has also been extended to support
customer care processes. This gives
you visibility of simplified line
quality information, letting you
design the workflows you need to
guide call center agents — quickly
and efficiently — through problem
resolution steps. By enabling agents
to take an active role in problem
resolution, operational costs and
service downtime will be significantly
reduced. What’s more, better support
means happier customers.

Advanced and comprehensive
troubleshooting capability
The Alcatel-Lucent 5530 NA
provides a wide array of testing
capabilities allowing you to detect,
diagnose and troubleshoot any and
all problems affecting customer lines.
It will allow you to check line state
information, perform line quality
diagnosis (in-depth line diagnosis,
including in-service and over-the-
time diagnosis results), and provide
you with tools for problem loca-
tion and specialized field technician
tools. Among the list of available
tests, some are non-intrusive and
can be executed while the service is
running, enabling the detection of
problems that would otherwise go
unnoticed. The Alcatel-Lucent 5530
NA also supports the newly released
Alcatel-Lucent Smart DSL designed
to protect lines from external noise.
Alcatel-Lucent Smart DSL will not
only stabilize lines, resulting in a
dramatic improvement to customer
quality of service, but will also stabi-
lize lines at a greater bit rate.
In sum, the Alcatel-Lucent 5530
NA lets you successfully resolve
line problems, quickly, simply and
cost-effectively.
Rationalizing your
testing architecture
Network evolution scenarios for
Class 5 switch replacement include
the implementation of POTS line
cards in the access node. This trans-
formation option can apply to access
nodes deployed in Central Offices
(COs), or to nodes deployed in out-
side plants (FTTN architecture).
The Alcatel-Lucent 5530 NA will
help you to cope with network
evolution thanks to the support of
extended Narrowband Line Testing
capabilities. These include inward
POTS self-testing, as well as loop
and POTS terminal testing (voltage,
current, capacitance, ring tone, loop
back, etc.). By handling both DSL
and POTS testing from the Alcatel-
Lucent 5530 NA, you will be able to
rationalize your testing architecture.

Embedded line testing technologies
The Alcatel-Lucent 5530 NA relies on several embedded testing technologies.
The Single Ended Line Test (SELT) is a reflectometric test mainly aimed at
measuring line length and locating line problems. Consequently, it is used
for the estimation of potential line capacity or for the location of possible
line impairments.
The Dual Ended Line Testing (DELT) is based on the exploitation of DSL
physical layer parameters. DELT testing identifies issues on the higher line
frequencies, and enables the detection of problems such as bad contacts,
interference, unbalanced loops, etc.
The Narrow-Band Line Testing (NBLT) includes an array of electrical
tests such as POTS LT self-test tests and telephone terminal tests. These
are supported by the POTS ports implemented in the ISAM products family,
which integrates voice capability.

How the Alcatel-Lucent 5530 NA works

Alcatel-Lucent 5530 Network Analyzer10
Coping with your evolving access network
The Alcatel-Lucent access testing approach delivers testing capabilities in the
Access nodes themselves, thus removing the need for test access matrices and
costly external test-head solutions. Furthermore, as your access network evolves
with the integration of POTS line cards (Class 5 replacement), you will be able
to rely on the Alcatel-Lucent 5530 NA to serve as a single integrated testing
solution for DSL and POTS.
Over-the-time monitoring
Broadband services transported in high frequencies are more likely to be affected by line impairments
such as bad contact, crosstalk, or interference. Because these problems are intermittent by nature,
traditional line testing systems find them difficult to detect. But this can all change with the
continuous line monitoring capability of the Alcatel-Lucent 5530 NA. Now such problems can
be easily detected, along with their probable cause. The net result is faster reaction and problem
resolution, especially for those troublesome and persistent line problems that you may currently
leave unresolved.
