The implementation of TDM service in EPON system

A main issue to be resoled urgently in multi-service supported EPON system is to find a reasonable solution for TDM service access. This paper introduces a suitable TDM access scheme which is the combination of VoIP and CESoP technology. In our EPON system design, VoIP and CESoP technology are applied respectively to deal with two main kind of TDM service - Voice and Leased line(such as E1/T1). The scheme has been implemented in our EPON system and has achieved good results in some triple-play pilot projects.
