Chang Ying1, He Yan1, Lu Yan3, et al. Design and implementation of mode switching program in dual-mode ONU[J]. 2013,(4):5-7. DOI: 10.13756/j.gtxyj.2013.04.011.
For correct identification of current systems prior to dual-mode ONU registration
this paper presents two switching methods.In relation to the possible switching conditions for dual-mode ONU
it selects a switching method appropriate for the current switching scenario and designs and realizes an ONU automatical identification for current GPON/EPON systems
fascilitating hybrid deployment of access systems and providing an option for the convergence of the two technologies.
