4.3 The Layer-2 Interface PTM Screen
The VDSL Router must have a layer-2 interface to allow users to use the DSL port to access the
Internet. The screen varies depending on the interface type you select. Log into the VDSL Router's
web configurator and click Advanced Setup > Layer2 Interface > PTM Interface to manage
the PTM layer-2 interfaces.
Note: The ATM and PTM layer-2 interfaces cannot work at the same time.

DESCRIPTION
Select the scheduler to use for queues that have the same precedence as the default
queue. Queuing applies only when a port has more traffic than it can handle.
Weighted Round Robin scheduling services queues of the same priority level on a
rotating basis based on their queue weight. The higher a queue's weight, the more
service it gets. This queuing mechanism divides any available bandwidth across the
different traffic queues and returns to queues that have not yet emptied.
Weighted Fair Queuing guarantees each queue's minimum bandwidth based on its
queue weight during traffic congestion. This queuing mechanism divides any available
bandwidth across the different traffic queues. Weighted fair queuing handles packets of
various sizes better than weighted round robin queuing does.
Specify the VC's weight for weighed fair queuing. The higher the weight, the bigger
portion of the bandwidth the VC gets.
Specify the VC's priority for weighed fair queuing. The smaller the number the higher
the priority.
Specify the VC's weight for weighted round robin queuing. The higher the weight, the
bigger portion of the bandwidth the VC gets.
Specify the VC's priority for weighted round robin queuing. The smaller the number the
higher the priority.
