Structural cabling

Designing and implementation of computer network 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

Project completing-general access to solution 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

Transmission medium types 1 Criteria: 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

Transmission medium Type 2 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

Layer 2 i Layer 3 - Design 1 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

Layer 2 and Layer 3 - Design 2 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)

Implementation process 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
