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.^*
