ADSL
interface:
Asymmetric
digital
subscriber
line
(ADSL)
is
a
type
of
digital
subscriber
line
(DSL)
technology,
a
data
communications
technology
that
enables
faster
data
transmission
over
copper
telephone
lines
than
a
conventional
voiceband
modem
can
provide.
Use
a
RJ11
cable
to
connect
the
ADSL
port
of
gateway
device
to
the
DSLAM
at
ISP,
and
connect
further
to
a
conventional
Internet
Protocol
network.
Ethernet
over
ATM
with
NAT
WAN
type:
The
option
is
intended
to
be
used
in
implementations
which
use
ATM
networks
to
carry
multiprotocol
traffic
among
hosts,
routers
and
bridges
which
are
ATM
end
systems.
IP
over
ATM
WAN
type:
Select
this
option
if
ISP
provides
VPI/VCI,
VC
‐
based/LLC
‐
based
multiplexing,
IP
address,
subnet
mask,
gateway
address
and
DNS
to
you
to
setup
an
ADSL
Internet
connection.
PPPoE
(ADSL)
WAN
type:
Select
this
option
if
your
ISP
requires
you
to
use
a
PPPoE
connection
for
accessing
Internet.
This
option
is
typically
used
for
DSL
services.
PPP
over
ATM
WAN
type:
The
Point
‐
to
‐
Point
Protocol
over
ATM
(PPPoA)
is
a
network
protocol
for
encapsulating
PPP
frames
in
AAL5.
It
is
used
mainly
with
DSL
carrier.
RFC
1483
Bridged
WAN
type:
RFC1483
Bridged
is
for
carrying
connectionless
network
interconnected
traffic
over
an
ATM
network.
Bridging
performs
higher

layer
protocol
multiplexing
implicitly
by
ATM

Internet
Connection
Configuration
To
setup
the
Internet
connection
profile
for
each
physical
WAN
interface,
you
must
specify
its
WAN
Type
for
the
interface
and
then
define
related
parameters
for
the
WAN
type.
So
the
gateway
will
connect
to
ISP
that
you
subscribe
to,
and
ISP
further
links
the
connection
to
the
Internet.
WAN
Type
varies
from
interface
to
interface.
Based
on
physical
interface,
the
supported
WAN
Types
and
related
settings
are
shown
as
below.
In
the
example
bellow,
the
IOG761AM
‐
0TDA1
is
used
to
show
the
Internet
connection
configurations
as
it
includes
most
kinds
of
physical
interfaces.
