scope:

The present document describes cost effective and flexible access networks using optical fibre technology. The present document is designed to provide both services to meet the current demands and an infrastructure, which is able to satisfy the requirements of the future. The present document describes the characteristics of an Optical Access Network (OAN) with the capability of transporting interactive services, based on 64 kbit/s bearer capabilities, between the User Network Interface (UNI) and the local exchange. The present document considers an OAN capable of providing business and residential customers with a range of services (up to 2 Mbit/s) over a passive split optical network. Distributive services (e.g. cable television) are outside the scope of the present document.
