IP Address Planning
These IP addresses are valid only between OLTs and ONUs and
therefore can be planned as private IP addresses.
VLAN Planning
l ONUs and the OLT must
use single VLAN tags.
l Service flows of the same
enterprise has the same
VLAN on the OLT.
l Service flows of the same
enterprise can have
different VLANs on
ONUs but the VLANs
must be translated to the
same VLAN on the OLT.
Use a reserved CVLAN
(starts from 4000).
NOTICE
A reserved CVLAN cannot be
used for Ethernet services on
ONUs.

OLT
The OLT allocates
a global SVLAN to
each enterprise:
