Abstract

A number of ADSL subscribers are explosively increasing every year. The ATM over ADSL gives us a new paradigm for Internet access service using existing copper cable. An ATM network takes the role of access network for providing the Internet access service using the ATM over ADSL. However, it is very difficult for network service provider to manage the large-scale ATM access network in uniform in terms of the stabilized Internet access service provision using the ATM over ADSL model. We logically divide the ATM access network into two domains from the perspective of fault management. The first domain is composed of DSLAMs and the seconds one is composed of the pure ATM switches. This paper proposes two level fault management schemes for ATM over ADSL service provision in terms of TMN functional layering: one is the fault management in terms of the network management layer (NML) and the other is one in terms of the service management layer (SML). We also describe the experience learned from the network management under the real network applying the proposed fault management schemes.
