LABEL
DESCRIPTION
General
Active
Select
Enable
or
Disable
to activate or deactivate the interface.
Name
Specify a descriptive name for this connection.
Type
Select whether it is an
ADSL/VDSL over PTM
,
ADSL over ATM
connection or
Ethernet
.
Mode
Select
Routing
if your ISP give you one IP address only and you want multiple computers to share
an Internet account.
Encapsulation
Select the method of encapsulation used by your ISP from the drop-down list box. This option is
available only when you select
Routing
in the
Mode
field.
The choices depend on the connection type you selected. If your connection type is
ADSL/VDSL
over PTM
, the choices are
PPPoE
and
IPoE
. If your connection type is
ADSL over ATM
, the choices
are
PPPoE
,
PPPoA
,
IPoE
and
IPoA
. If your connection type is
Ethernet
, the choices are
PPPoE
and
IPoE
.
IPv4/IPv6 Mode
Select
IPv4 Only
if you want the VMG to run IPv4 only.
Select
IPv4 IPv6 DualStack
to allow the VMG to run IPv4 and IPv6 at the same time.
Select
IPv6 Only
if you want the VMG to run IPv6 only.
ATM PVC Configuration (These fields appear when the
Type
is set to
ADSL over ATM
.)
VPI
The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.
VCI
The valid range for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM
traffic). Enter the VCI assigned to you.
Encapsulation
Select the method of multiplexing used by your ISP from the drop-down list box. Choices are:
•
LLC/SNAP-BRIDGING:
In LCC encapsulation, bridged PDUs are encapsulated by identifying
the type of the bridged media in the SNAP header.
•
VC/MUX:
In VC multiplexing, each protocol is carried on a single ATM virtual circuit (VC). To
transport multiple protocols, the VMG needs separate VCs. There is a binding between a VC
and the type of the network protocol carried on the VC. This reduces payload overhead
since there is no need to carry protocol information in each Protocol Data Unit (PDU)
payload.
Service
Category
Select
UBR Without PCR
for applications that are non-time sensitive, such as e-mail.
Select
CBR
(Continuous Bit Rate) to specify fixed (always-on) bandwidth for voice or data traffic.
Select
Non Realtime VBR
(non real-time Variable Bit Rate) for connections that do not require
closely controlled delay and delay variation.
Select
Realtime VBR
(real-time Variable Bit Rate) for applications with bursty connections that
require closely controlled delay and delay variation.
PPP Information (This is available only when you select
PPPoE
or
PPPoA
in the
Mode
field.)
PPP User Name
Enter the user name exactly as your ISP assigned. If assigned a name in the form user@domain
where domain identifies a service name, then enter both components exactly as given.
PPP Password
Enter the password associated with the user name above. Select
password unmask
to show your
entered password in plain text.
PPP Connection
Trigger
Select when to have the VMG establish the PPP connection.
Auto Connect
- select this to not let the connection time out.
On Demand
- select this to automatically bring up the connection when the VMG receives
packets destined for the Internet.
