Solutions for diagnostic
failures in HFC networks
What is the Visium?
The
association
of
Mathematical
Programming, Search in Graphs and Artificial
Intelligence techniques generates powerful
auxiliary tools for decision making in diverse
fields of the human knowledge.
Using this technology, Tele Design has
developed the VISIUM — Expert System for
HFC Fault Diagnosis and Location, capable of
starting its inference process with information
obtained from subscribers calls, monitoring
systems
via
SNMP
(Simple
Network
Management Protocol), when available, or
through information from the CMTS (Cable
Modem Terminal System).
This capability enables the reduction of
investments, operational costs and customer
service time.
ARTIFICIAL INTELLIGENCE
VISIUM is capable of making inferences soly on information that comes through the
subscribers's calls. Making possible reducing the investment in hardware to acquire
network failure data.
With the appropriate handling of the events, whether originating from subscribers's calls
(informing service interruption or degradation) or from the monitoring system, and its
capacity to learn, VISIUM guarantees fast and precise answers to the necessities of HFC
management networks.
GRAPHIC INTERFACE
VISIUM has intuitive and full graphic interface
that allows a global view of the area being
monitored (multinodes), the status of each node
and detailed views of each equipment with its
precise location, by pole or vault.
In the general view the changing of the colors
on the buttons, which represent nodes, brings
information of the fault severity allowing the
best
allocation
of
available
maintenance
resources. The number of subscribers with
interrupted service is the main information
shown on the node button.
ADVANTAGES
With a simple mouse click on this button we have the node's full vision and up-to-themoment inference results on affected consumers, poles where the calls occurred and the
possible cause of the problem. With the aid of VISIUM the operator can be pro active and
anticipate actions to back up the service, improving the subscriber perception of quality.
The complete view of the node uses graphic computing resources, enabling the visualization
of the affected consumers and poles, poles where the calls occurred, and the possible root of
the problem in a clear and objective way, as opposite to digital maps shown by commercial
GIS software. Going to the network design level, additional windows may even inform which
equipment is on the poles or vaults, the number of connected subscribers to them, as well
as the related addresses.
ADVANTAGES
With the inference of the problem's cause,
Óptico
field teams can be directly driven to the most
Node
likely point of failure. Feedback of these teams
to the controller in the operation center
confirms
the
inference
or
generates
new
information, allowing VISIUM to continue its
inference process, offering new locations and
diagnosis instantly. This interaction, carried
through without the aid of paper maps, reduce
the fault location time more than 70%, thus
reducing the time of non-rendered service.
All those who have already operated large
scale networks know of the difficulties in
searching
for
information
from
map
collections, especially in stressful situations,
when there is service interruption at various
points.

ADVANTAGES
Moreover, keep paper maps available and up date demands investment and great organizational
discipline. With VISIUM the paper maps are not more necessary. All the topology information and
equipment in the network are shown. The graphic update of the network's representation in the
VISIUM is made by the simple importation of design files.
The clustering of operations finds in VISIUM the ideal tool for fault monitoring and detention. From
a single environment, it is possible to control up to 300 nodes per open VISIUM instance. Views of
cities, HUB areas, nodes and their respective problems given by VISIUM makes it an important
ally in the management of HFC networks.
