can operate in the "router" or "bridge" modes depending on the ONT configuration. The chart shows all
services configured in the "router" mode.
All broadcast and unknown unicast traffic is redirected to a dedicated broadcast GEM port in this
model. Broadcast and unknown unicast packets come to S-VLAN in the ONT. These packets are
transmitted into the corresponding U-VLANs on the ONT side. In this case, broadcast and unknown
unicast are replicated neither in the OLT nor in the ONT since every service has a separate S-VLAN for
broadcast and unknown unicast traffic.

Thus, the model implements "VLAN for Service".
