The preceding chapters explain the G-PON infrastructure and the basic tools. In this chapter, we finally get to the question of delivering telecommunications services to end users, subscribers. This chapter shows how G-PON and OMCI model these services and manage them. To a considerable extent, service definitions are independent of access network technology, but some aspects are affected by PON as the server layer, and the specifics of the OMCI management model tie this chapter directly to G-PON.^*

Each telecommunications operator has its own service model, so the services described in this chapter are necessarily generalizations. Common aspects of the system requirements are defined in two standards streams, both of which are recommended for further study.

ITU-T G.987.1 defines the FSAN operators' requirements for XG-PON. G.987.1 assumes G.984 G-PON as a baseline and is to a considerable extent an explicit restatement and extension of G.984 G-PON requirements, some of which are implicit. It is a view that emphasizes the desired continuity with G.984, ...
