Abstract
Currently,Asymmetric Digital Subscriber Line (ADSL) is the most noticed technology in xDSL family.Using twisted-pair copper line as access medium is one advantage of ADSL because this medium has been widely distributed.Also,ADSL adopts point-to-point architecture,which brings more flexibility to set up networks.This paper is based on the development of ADSL system.It includes the architecture of ATM(Asynchronous transfer mode) over ADSL broadband access network.We concentrate our attention on hardware and software function designs of ATM over ADSL ATU-C and ATU-R cards.
