port is depicted as a box labeled EPON. The two User Ports are represented by boxes labeled UNI-1 and UNI-2 respectively. Depending
on whether the EPON Port or a User Port is currently selected the FIFOs shown will correspond to either the upstream or downstream
data path. The convention is “from port to FIFO.” Thus selecting a port “from” which a frame is received displays the FIFOs to which the
frame may be classified. Classification will be discussed in the next section. Selecting any FIFO terminating at a particular port or logical
link has the effect of also selecting the related entity. In the example above link 1 has been selected.
Notice that downstream FIFOs are labeled relative to their associated link. For downstream FIFOs the GUI
uses the naming convention Link.FIFO. Therefore the “full name” of the selected FIFO is 1.1.
Upstream the GUI will use the convention Port.FIFO. In the example above the full FIFO name is 1.2,
indicating that the FIFO is #2 of User Port 1.
11.1.2 Provisioning Number of Logical Links to Register
Up to 3 Links may be registered per ONU (6 on a TK3711). The number of Logical Links is determined by
the Num LLID control. This control is only visible when one of the User Ports is selected.
11.1.3 Provisioning Number of User Ports
In practice either ONU user port may be used exclusively. However, for the purposes of the GUI only User
Port 1 may be used exclusively. To select whether both User Port 1 and 2 should be used, or only user port
1, set the number of ports to 2 (both ports) or 1 (only port 1). The number of ports will not be changed if all
of the FIFOs have already been allocated to user port 1, or there is insufficient FIFO space available. The
Num Port field is only visible if the EPON port is selected.

Step 1.
Downstream FIFOs are associated with ONU user ports. The Entity Selection Control displays queues using a “From-To”
convention. To add a queue to an ONU User Port, first click on the
ONU EPON port (“From”) and then select any one of the ONU User Port’s FIFOs (“To”).
