To ensure that design wiring projects structured are effective and efficient, raised thefollowing rules:
Find a complete solution for
connectivity: To achieve networkconnectivity solution covers all systems
that are designed to connect, build,
manage and identify structured cabling
systems.

Plan for future growth: It is
essential that any new installation
complies with the standards to
ensure that the infrastructure is in
place.
Note the total cost of ownership:
Great part of the installation and
long-term costs associated with
modern network systems aredirectly related to reliability and
network connectivity .

Keep the freedom to choose
providers: A system with a single
vendor, and that does not comply with
the standards, will make it harder tobe able to change the addresses
below, although there are short term
assurance and certification benefits.

There are five subsystems system wiring-related structured:
Point of demarcation (demarc).
Chamber Telecom (TR).
Cabling backbone (cabling vertical).
Cabling distribution (wiring horizontal).
Workspace.
-
8/9/2019 Presentacion en Ingles Cap 7

The point of demarcation (demarc) is located where external
cables from the provider service work together with the local
system. Backbone cabling is the "main line" of the system.
Horizontal cabling distribution services in the areas of work.

All major standards specify thateach hardware connection drive
must have a unique identification.
This identifier must be marked on each unit of
the hardware or its label; connections forworkstations must have a label on board, rack
or connector.

Cables are labelled once they
are cut from the reel, each
connection cable also mustlabel in the panel room
telecommunications connection
this facilitates localization and
the diagnosis of problems.

Make sure the cord to the laying ofcables be loose, tying some knots
around cables, by placing the tape at the
ends.
It is also good practice the registering of
beginning and end of a cable distances
using distance indicators marked in the
lining of the cable.

IEC suggests the following to register:
Cables: Type and number of cables and pairs, location of
the endpoint.
Shots of the workspace: Type, label, informationlocation.
Boards of telecommunications (distributors): Number
of room, type, description, connections, location.
Floor plans: Shots, telecommunications rooms and
routes cabling locations.

IEC recommends that system wiring information is maintained in a database with five
fields:
Field 3: Component identifier
Field 1: Specific location Field 2: Overall location
Field 4: Port number
Field 5: Physical data

Cable access is not
connected or marked for
future use is considered to
be abandoned. Abandonedcable is a source of fuel for
fires. Abandoned cables
can also form a track
voltage, as well as be the
source or driver EMI and
RFI.

The demarcation point is the point atwhich the external cabling connects
to backbone cabling within the
building. Represents the boundary
between the responsibility of the
service provider and the customer.
Everything that happens from thepoint of demarcation in the building
is the responsibility of the customer.
The service provider is responsible
for everything that occurs from the
demarcation point to the installationof the service provider.
