Description

technical field

[0001] The present invention relates to realize the VoIP (Voice over IP) service intercommunication technology of optical network unit (ONU) under the same optical line terminal (OLT) of Ethernet passive optical network (EPON), specifically relate to realizing the same OLT in EPON system Interworking of VoIP services. technical background

[0002] In the EPON system, an OLT provides a Gigabit Ethernet port upstream, and provides an optical fiber downstream through an optical splitter (ODN) to separate 16 to 32 optical fibers, and each optical fiber is connected to an ONU device as an ONU Uplink port, ONU provides several 100 / 1000M Ethernet interfaces as user ports to connect VoIP module, user's computer, Ethernet switch, Ethernet router or other Ethernet devices. After the user data enters the user port of the ONU, the ONU uploads it to the OLT through the optical fiber, and the OLT does not exchange the data with other ONUs, but only sends it through the up...
