Theabstract
TWISTED PAIR, CABLE, CCYC, SWITCH, THE LINE, TRANSFER, FAST ETHERNET, COMMUNICATION, SYSTEM, SPEED.
The degree project contains an explanatory slip of 96 pages, 3 sheets of a graphic material, 13 tables and 16 figures located in the text.
Problem of the project is design of a local corporate network of voice provision on the basis of software-hardware complex Media-Matrix for the Center of Children's and Youthful Creativity. The Fast Ethernet technology was chosen as transport technology.
In the project were overviewed the problems, connected with most efficient equipment for the local area network of voice provision, projected bit rate makes 200 Mbit\s. There was a feasibility report and the problems tangent of the safety precautions in the project and a labor safety was affected.
Calculation of a necessary length of a copper cable, voice cable, calculation of useful transmission network capacity, line channel attenuation, transient attenuation and immunity and noise stability of a link was affected; technical characteristics of the equipment for realization of the project of a corporate local area network of voice provision are resulted.
