Paper Abstract

Many kinds of fiber access systems are being used to offer various services economically. They are based on different transmission technologies and fabricated by different vendors. A fiber access network operation system (OpS) must achieve common management of different type transmission equipment to offer all services efficiently. Since the network termination equipment called Optical Network Unit (ONU) is placed in or near the customer's premise, the fiber access network OpS must utilize a remote operation mechanism to manage the ONU. This paper proposes the assignment of management functions for the equipment of fiber access systems, from the view point of OpS efficiency. An NE (Network Element) has a management portion and manages different types of equipment in a common manner. This paper also describes the interface between management portion and network element body in the transmission equipment, which allows us to use the same management block between different vendor equipment sets. We show the efficiency of this management function assignment by discussing the alarm surveillance function of the NE. Additionally, we describe a remote control mechanism that achieves ONU operation in the management portion of the central office.
