Abstract
The objective of this research was to build a broadband coaxial cable network. One of the basic requirement of a network is the physical link transmission medium. For the purposes of this research, broadband coaxial cable was chosen as a physical medium of data communication. The approach taken in this research was to divide network design into three main steps. In the first step, the decision on topology of the network was determined. Both Star and Minimum Spanning Tree topologies were used and then the Esau-Williams Algorithm was employed to minimize the cable length. In the second step, various signal levels of the system were determined based on the longest cable route identified in the topology designed in the first step. In the third and final step, based on the previous steps, the active and passive devices were laid out in the cable route and their effects on signal levels along the cable, including cable attenuation, selecting tap values, frequency response and equalization, peak-to-valley response, tilted system operation and equalizer value calculations, were considered for the system layout.
The validation approach taken in this research was to examine the designed network and to determine wheather it met the MAP/TOP broadband specification. If the input/output levels of the design complied with the required system performance parameter, the results of the network design would also comply with the MAP/TOP broadband specification.
The tree structure of the network was then decomposed into a series of parent and child relationships with new constraints which met the overall constraints of the entire network. Devices were laid out according to the design parameters determined during system design which were in tern, based on MAP/TOP broadband specification and it had been demonstrated that prototype dBLAN produces a broadband cable cable network design which met the MAP/TOP broadband specification which verified and validated the developed system.
