Scope
Purpose Scope The purpose of this TR is to summarize the variations of NGN access networks/technologies for wireline access networks. The wireline access technologies discussed in this document are: Digital Subscriber Line (DSL)@ Fiber [Broadband and Ethernet Passive Optical Networks (PONs)]@ Cable@ and Metro Ethernet access networks. The scope of this TR is described in terms of: ? Architecture and description of functional entities. ? Call/session flows. ? Interfaces and associated protocols. ? QoS and policy mechanisms. This TR is intended to serve as the reference architecture document for the Emergency Telecommunications Service (ETS) wireline access requirements.
