Fiber Access Networks

WT-280 focuses on GPON systems in an unbundled services environment that addresses requirements not covered by TR-156. TR-156 and WT-247 address basic L2 GPON systems. There are "more complex" types of ONT and Service Providers have more complex requirements that need a reference in BBF GPON framework. ITU standards already cover these more complex functionalities from an OMCI point of view. What is missing are the architectural/functional requirements. 

A number of Broadband Forum Technical Reports are dedicated to the description of an Ethernet-based architecture optimized for multi-service PON networks and technical requirements for PON systems catering to both residential and business customers.

Based on TR-221, this document extends the architecture and technical requirements to providing enhanced mobile backhaul functionality. These requirements cover system architecture, use cases, technical requirements as well as some implementation guideline, so as to for foster multi-vendor interoperability. The specifications in this document apply to both ITU-T and IEEE PON systems and focus on LTE and LTE advanced.

The purpose of this Working Text is to specify a protocol that is executed between the OLT Channel Terminations and, based on the architecture and functional descriptions outlined in ITU-T Recommendation G.989.3, enables wavelength channel management within an NG-PON2 system.

Provides a framework for the remote configuration and management of services for Passive Optical Network access by multiple management protocols
