Operations method in an ethernet passive optical network that includes a network unit with multiple entities

In a passive optical network that includes an optical line terminal (OLT) and a plurality of optical network units (ONUs), a method for registration of multiple entities belonging to a specific ONU comprising the steps of:

• a checking, by the OLT, of a flags field residing inside are registration request message received from the specific ONU;
• and
• b) based on said checking, deciding, by the OLT, to register an entity selected from the group consisting of a user, a group of users and a service and associated with the registration request as an entity of said specific ONU selected from the group consisting of a first entity and an additional entity, the decision to register including providing a specific Logical Link Identification (LLID) to each entity of said specific ONU;
• wherein said step of deciding includes deciding that a flags field value is an old value, the method further comprising the step of deleting all previously registered entities for said specific ONU.
