IPoA Routed Connection
Profile Port
: Select the profile port ADSL.
Protocol:
The ATM protocol will be used in the device.
Description:
User-definable
name
for
the
connection.
VPI/VCI:
Enter the information provided by your ISP.
ATM Class:
The Quality of Service for ATM layer.
NAT:
The
NAT
(Network
Address
Translation)
feature
allows
multiple
users
to
access
the
Internet
through a
single
IP
account,
sharing
a
single
IP
address.
If
users
on
your
LAN
have
public
IP
addresses
and
can access
the
Internet
directly,
the
NAT
function
can
be
disabled.
MTU:
Maximum Transmission Unit. The size of the largest datagram (excluding media-specific headers) that IP will
attempt to send through the interface.
IP (0.0.0.0:Auto):
Enter the WAN IP for the router. Leave this at 0.0.0.0 to obtain an IP address automatically from
your ISP.
Netmask:
The default is 255.255.255.0. This can be changed according to the settings assigned by you ISP.
Gateway
: Enter the IP address of the default gateway (if specified).
RIP:
RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.
TCP MSS Clamp:
This option helps to discover the optimal MTU size automatically. Default is enabled.
Obtain DNS:
A
Domain
Name
System
(DNS)
contains
a
mapping
table
for
mapping
between
Domain
Names
and
IP addresses.
On
the
Internet,
every
host
has
a
unique
and
user-friendly
name
(domain
name)
such
as
www.helloworld.com
as
well
as
an
IP
address.
An
IP
address
is
a
32-bit number
in
the
form
of
xxx.xxx.xxx.xxx
,
for
example
10.0.0.2.
You
can
think
of
an
IP
address
as
a
telephone
number
for
devices on
the
Internet,
and
the
DNS
will
allow
you
to
find
the
telephone
number
for
any
particular
domain
name. As
an
IP
Address
is
hard
to
remember,
the
DNS
converts
the
friendly
name
into
its
equivalent
IP
Address.
You
can
obtain
a
Domain
Name
System
(DNS)
IP
address
automatically
if
your
ISP
provides
it
when
you logon.
To
use
this
automatically
supplied
DNS
check
the
Enable
box.
Primary DNS:
Enter the primary DNS.
Secondary DNS:
Enter the secondary DNS.

ADSL Mode
Connect Mode
:
This
mode
will
automatically
detect
your
ADSL
line
mode,
ADSL2+,
ADSL2,
G.dmt, G.lite,
T1.413,
AnnexM2
or
AnnexM2+.
But
in
some
areas,
multimode
cannot
detect
the
ADSL
line
mode very
well.
If
it
is
the
case,
please
adjust
the
ADSL
line
code
to
G.dmt
first.
If
it
still
fails, please
check
with your
ISP
for
line
connection
information.
Modulation:
It will automatically detect capability of your ADSL line mode. Please keep the factory settings unless
ADSL is detected as the symptom of a synchronization problem.
Profile Type:
The profile type should be left in the default settings unless the ADSL mode is determined as the
symptom of low link rate or instability problems. If such a problem is encountered, the profile setting may need to be
changed to conform to the different DSLAM in the area.
Activate Line:
Select
false
and
then
select
true
to
activate
any
new
Connect
Mode
settings.
Coding Gain:
This
reduces
the
router’s
transmit
power
and
will
effect
to
router’s
downstream performance.
General,
the
higher
the
gain,
the
higher
the
downstream
rate,
but
sometimes
a
gain
that
is too
high
will
cause
an
unstable
ADSL
connection.
The
configurable
ADSL
coding
gain
is
from
0
dB
to
7dB, or
automatic.

System
Here are the items within the
System
section:
Time Zone, Remote Access, Firmware Upgrade, Backup/Restore,
Restart
and
User Management.
Time Zone
The router does not have a real time clock on board; instead, it uses the Simple Network Time Protocol (SNTP) to
get the current time from an SNTP server outside your network. Choose your local time zone, click
Enable
and click
the
Apply
button. After a successful connection to the Internet, the router will retrieve the correct local time from the
SNTP server you have specified. If you prefer to specify an SNTP server other than those in the list, simply enter its
IP address as shown above. Your ISP may provide an SNTP server for you to use.
Daylight Saving
is also known as
Summer Time Period.
Many places in the world
adapt it during summer time to
move one hour of daylight from morning to the evening in local standard time. Check
Automatic
box to auto set
your local time.
Resync Period
(in minutes) is the periodic interval that the router will wait before it re-synchronizes the router’s
time with that of the specified SNTP server. In order to avoid unnecessarily increasing the load on your specified
SNTP server you should keep the poll interval as high as possible – at the absolute minimum every few hours or
even days.

DO NOT
power down the router or interrupt the firmware upgrading while it is still
in process. Improper operation could damage the router.
Remote Access
To temporarily permit remote administration of the router (i.e. from outside your LAN), select a time period the router
will permit remote access for and click
Enable.
You may change other configuration options for the web
administration interface using
Device Management
options in the
Advanced
section of the GUI.
If you wish to permanently enable remote access, choose a time period of
0
minute.
Firmware Upgrade
Your router’s “firmware” is the software that allows it to operate and provides all its functionality. Think of your router
as a dedicated computer, and the firmware as the software it runs. Over time this software may be improved and
revised, and your router allows you to upgrade the software it runs to take advantage of these changes.
Clicking on
Browse
will allow you to select the new firmware image file you have downloaded to your PC. Once the
correct file is selected, click Upgrade to update the firmware in your router.
