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.
