The position of the bridged tap is determined by that of the outlet in most modern apartments, since most of the indoor wiring utilizes the bus wiring structure when deploying the indoor communication line. These bridged taps deteriorate transmission performance in the specific frequency at the time of high-speed multimedia communication, which uses a high frequency bandwidth, since the duality of return loss worsens and line attenuation increases rapidly. As a result, analysis on this phenomenon is required. In this study, the test model is created by modeling the intercommunication facility of the apartment that is the most representative residential house type, and by understanding the structure and the environment of the indoor wiring. Also, how the bridge tap affects performance is analyzed when the VDSL service is provided, so that problems of intercommunication lines can be identified and methods for improving the proper intercommunication line can be suggested, which is suitable for accommodating high-speed multimedia service of the future.

Telecommunication network has been constructed and developed to provide voice. data, and simple image communication service in accordance with the demand increase and the various service tendency according to the growth of social economy It is expected that various multimedia services are transmitted and received through a telecommunication media. First of all, for the sake of realization of these schemes in house, it is essential to make the customer premises networks to be higher level. Especially, the demand increment of customer services and the improvement of technology would be expected to be a result of a main-stream strategic industry. This paper briefly describes investigation results concerning technical development and standardization trends of advanced nation, and introduce technical development and standardization plan which the Government is presently carrying out. We also proposes the schedule of technical development and standardization plan related to international standard.
