Design And Implementation Of A Multiservice Broadband Access Network Platform

To provide multiservice in access network may effectively reduce operetion , maintenance and network construction expense and also increase network utilization rate. It is practicable to build multiservice broadband access network with QoS guarantee using multiservice broadband access device supporting GPON and multicast and lots of QoS function. To study and develop a multiservice broadband access device is task of the research,which has independent intellectual property right and high commercialization degree.The research of the thesis is framework design of the device,the whole plan of hardware and software design,the schematic circuit design,and PCB layout , electromagnetic compatible design,signal integrality design and hot design. In this paper , the design and implementation of such a multiservice broadband access device is expounded by function modules,essential and difficulty are also discussed.
