What's the Methods for ONT processing of ethernet message?
The method of ONT processing of ethernet messages, comprinsing:
A- The ont receiving an ethernet message from the UNI and if the ethernet message doesn't contain a VLAN tag , adding the VLAN tag specified in the native VLAN property of the UNI to the ethernet message before forwarding it to the GPON protocol processing module and otherwise forwarding the ethernet message to the GPON protocol processing module.
B- The ONT receiving the downstream ethernet message with VLAN tag from the GPON protocol processing module and if the VLAN tag of the Ethernet message is the same as the one specified in the native VLAN property of the UNI, removing the VLAN tag before forwarding it to the equipement connected to the UNI for the Ethernet message via the UNI , otherwise directly forwarding the Ethernet message to the equipement connected to the UNI for ethernet message.
It's so important for every engineer to understand this process.
