For providing broadband and multi-service, access network is now evolving rapidly by merging new technologies to the existing technologies, and also implemented as various types of network in a network operator environment. MAIN is under development as integrated access network platform which enables to accommodate ATM/SDH-based and ATM/PON-based FTTx access architecture simultaneously, and provides upcoming services on the existing copper wires by adopting VDSL technology. But, since this network area is under multi network provider environment, merging new technologies and having vague boundry to private network, it needs a more specific management framework in point views of access network. With this when we design the OA&M, it is always required that we consider the trade off between equipment cost and operational cost. In this paper, we aim to establish an access network OA&M framework through design and implementing the system and network management of the MAIN. For doing this, firstly we discuss management architectural approach and design considerations, and then propose the MAIN management architecture model. In addition, we present the implementing architecture of NEL system and EMIL OS for the MAIN OA&M. As a result of those, we propose the MAIN OA&M framework as a reference model to design and implement other access networks.

The billing management techniques for multiple services in the B-ISDN network have been rarely developed. In fact, the management techniques including billing management only focus on a single service environment. In this paper, we propose a billing management system architecture for the multiple services in a Broadband access network. The architecture is based on OSI system management infrastructure and TMN Q3 interface to exchange and process the billing information from access node that is an ATM Cross-connecter. The system is designed to actively adopt the rapidly changing service environments and B-ISDN network management techniques. Futhermore, this system supports multiple services providers by real-time collector and charging functions for their requirements compared to the previous methodologies that only use the statistical data.
