The following table describes the fields in this screen.
4.4 The WAN Service Screen
Use this screen to change your VDSL Router’s WAN settings. Click Advanced Setup > WAN
Service. The summary table shows you the configured WAN services (connections) on the VDSL
Router.
To use NAT, firewall or IGMP proxy in the VDSL Router, you need to configure a WAN connection
with PPPoE or IPoE.
Note: When a layer-2 interface is in VLAN MUX Mode, you can configure up to five WAN
services on the VDSL Router.
Table 16
Layer-2 PTM Interface Configuration
LABEL DESCRIPTION
Select DSL Latency Select Path0 (Fast) to use no interleaving and have faster transmission (a “fast
channel”). Suitable only for a good line with little need for error correction.
At the time of writing the VDSL Router supports fast mode only and interleaved is
reserved for future use.
Scheduler Select the scheduler to use for queues that have the same precedence as the default
queue.
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.
During traffic congestion Weighted Fair Queuing guarantees each queue's minimum
bandwidth based on its default queue weight. This queuing mechanism divides any
available bandwidth across the different traffic queues. Weighted fair queuing applies
only when a port has more traffic than it can handle.
Default Queue
Weight Specify the PTM interface’s weight for weighed fair queuing. The higher the weight, the
bigger portion of the bandwidth the PTM interface gets.
Default Queue
Precedence Specify the PTM interface’s priority for weighed fair queuing. The smaller the number
the higher the priority.
Default Queue
Shaping Rate Specify the maximum transmission rate allowed for traffic on this queue.
Default Queue
Shaping Burst Size Specify the maximum number of cells that can be sent at the default queue shaping
rate.
