Investigation of time delay trunk ATM-network

Summary form only given. The article presents ATM-technology on the level of access network and trunk network. Four reference customers' connection configurations and main conceptions of access net-work building based on optical fiber are analyzed. Article shows two methods for logical network topologies using effectiveness and network productivity calculation, theoretically defined these parameters influence on time delay in local and municipal networks. Time delay is defined for ATM-network using different types AAL protocols and its change in dependence upon network traffic trunk increase. As result the theoretical calculation is determined for the effectiveness of bus and ring topology with optical fiber use and for the effectiveness of equipped AAL protocols based on time delay for different multimedia applications.
