25.1
Operating Principle
The "configuration model" concept is used for implementation of different service models in the
terminal. A configuration model defines general principles for data communication channelling for both OLT
and ONTs.
—
Model 1 is an implementation of the "VLAN for Subscriber" service model. The model does not have
dedicated broadcast GEM ports and uses U-VLAN on the ONT side.
—
Model 2 is an implementation of the "VLAN for Service" service model. This model uses a dedicated
broadcast GEM port.
—
Model 3 is an implementation of the "VLAN for Service" service model. This model uses a dedicated
broadcast GEM port. It differs from Model 2 by the order of S-VLAN to U-VLAN modification.
