Configure the DSL Router IP address and Subnet Mask for LAN interface. It is
also possible to enable DHCP server on the LAN, by defining the IP address
range and leased time. A second IP address and Subnet Mask for LAN interface
can be enabled by selecting the last checkbox.
Save button only saves the LAN configuration data.
Save/Reboot button saves
the LAN configuration data and reboots the router to make the new
configuration effective.
Quality of Service
1
By clicking on
Quality of Service
in the Advanced Setup menu, it is possible
to configure network traffic classes.QoS button will only be displayed to a
qualified PVC when all of the following conditions are met:
PVC is not in bridge mode (i.e. the WAN protocol can be PPPoA,
PPPoE, IPoA, MER);
PVC is in set to one of the following ATM service category: UBR
with PCR, UBR without PCR, non realtime VBR;
There are enough ATM TX queues left in the System.
If no traffic class is set, then it is possible to configure QoS by clicking on Add.
If a class has already been set, then it is possible to remove it by selecting
“remove” checkbox and clicking on Remove.
Each QoS-enabled PVC will consume 3 ATM TX queues. QoS consumes 1 TX
queue for transmitting OAM F5 cells for all PVC’s
2
. The overall number of ATM
TX queues for the whole system is 8. Setting up the first PVC with QoS enabled
1.
Quality of Service is currently not supported in ADSL AnnexB software release.
2.
This restriction is temporary and will be removed in the future.

requires 4 TX queues. Setting up the second PVC with QoS enabled needs 3 TX
queues.
The following table shows the system capacity for maximum number of PVC’s,
with or without QoS enabled:
By clicking on Add, then the following page shows up.
IP QoS is executed in the IP layer. It will classify traffic according to the
classification rule. Each rule may contain a combination of the following
conditions: protocol (TCP, UDP, ICMP), source IP address/subnet mask,
destination IP address/subnet mask, source port (one or range), destination
port (one or range). The result of matching a classification rule will produce a
priority (high, medium, low) and a Type of Service (don’t care, Normal Service,
Minimum Cost, Maximum Reliability, Maximum Throughput, Minimum Delay).
Note that the original IP header TOS and PRECEDENCE values are not used in
the classification.

The Type of Service (TOS) of the matching rule will overwrite the original IP
header TOS field if “don’t care” is not selected.
The priority of the matching rule determines which ATM TX queue to send over
this PVC if the packet is routed to this PVC. The ATM SAR scheduler transmits
the packet according to the following order:
1)
ATM service category from the highest to the lowest order: CBR, rt-VBR,
nrt-VBR, UBR
2)
For the same service category: Proirity level from high to medium to low
3)
For the same priority level: round robin.
IP QoS will only take effect if the packet is routed to a QoS-enabled PVC. If it
is routed to a regular QoS-disabled PVC, it will be transmitted at the same
priority level as the low priority of a QoS-enabled PVC of the same ATM service
category.
Click on Save/Apply to store the QoS setting.
Routing
By clicking on
Routing
in the Advanced Setup menu, it is possible to configure:
Default Gateway
Static Route
RIP
Default Gateway
The following figure shows Default Gateway page, accessed by clicking on
Default Gateway
on the Advanced Setup --> Routing menu.

If Enable Automatic Assigned Default Gateway checkbox is selected, this router
will accept the first received default gateway assignment from one of the
PPPoA, PPPoE or MER/DHCP enabled PVC(s). If the checkbox is not selected,
enter the static default gateway IP address and/or a WAN interface. Click
'Save/Apply' button to save it.
NOTE
: If changing the Automatic Assigned Default Gateway from unselected
to selected, You must reboot the router to get the automatic assigned default
gateway.
Static Route
Click on Add in the following page to configure static route entry.
In case a static route entry is already present, then select it and click on
Remove to delete it.
The following figure shows the Static Route Add page.
