• Pogled Telecommunications d.o.o is engaged in
designing and implementation of computer networks
• The process is based on the requests and project
task (facility structure, number of operation units,
expansions expected in the period of several years)
• A long year experience mostly refers to 5e (Cat 5e)
standard
• At the very end of works, necessary tests are done
in order to check whether all the tasks have been
done successfully
• In the process of project development, drafts and
calculations for passive and active computer
networks are made
• If the campus structure is such, the number of inter
distribution frames (IDFs) has to be defined
• By careful analysis of the facility structure, the best
solution is chosen (e.g. the space above the
lowered ceilings can be used for cable hooking)
• The last step is to choose a type of transmission
medium
• Criteria:
1.
2.
3.
4.
5.
•
Length
Bandwidth (expansion is expected)
Resistance to interference (interbuilding)
Price
Simplicity of implementation and maintenance
Choice is narrowed to UTP Cat 5e and6, Multi and
Single Mode optical cables
• One of the tasks is premises marking, wall jacks and
fields on patch panels
• This access facilitates the process of designing and
further maintenance
• In accordance with the chosen solution, calculations
for passive computer network (racks , connection
modules, patch panels, total number of jacks) and
table display of total quantuty of the same (so called
Cut Sheet) are done
• LAN infrastructure is mainly based on LAN Switches
• Switches are installed in this way:
– POPs – access level – 100BaseTX UTP cables
– IDFs – distributive level – 1000BaseTX STP
cables, POP-IDF connection
– MDF core level 1000BaseLX, optical IDF-MDF
connections
– On basis of port density a corresponding layer 2
solution has to be chosen
• After successful implementation of layer 2 solution,
the equipment for layer 3 is chosen
• Also, if a project request is such, it is necessary to
define layer 3 addresses for the end user stations
• Thereby, the way of out-routing should be taken into
consideration (depending on routing protocol, it is
necessary to choose a hierarchical mode of
addressing which will enable summarization of
addresses)
• After successful project design, the process of
implementation is being done
• Pogled Telecommunications d.o.o. employs the
expert staff capable to successfully accomplish such
a complex task
• At the end, by means of corresponding equipment
detailed tests are done so as to check the quality of
works done
