LABEL
DESCRIPTION
General
Name
Enter a service name of the connection.
Type
The interface type used by the ZyXEL Device is
ADSL
. The ZyXEL
Device uses the ADSL technology for data transmission over the DSL
port.
Mode
Select
Routing
(default) from the drop-down list box if your ISP give
you one IP address only and you want multiple computers to share an
Internet account.
WAN Service
Type
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 are
PPPoE
,
PPPoA
, and
IPoE
.
ATM PVC
Configuration
VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define
a virtual circuit.
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.
DSL Link Type
If your
WAN Service Type
is
PPPoE
or
IPoE
, the DSL link type is set
to
EoA
(Ethernet over ATM) to have an Ethernet header in the packet,
so that you can have multiple services/connections over one PVC. You
can set each connection to have its own MAC address or all connections
share one MAC address but use different VLAN IDs for different
services.
EoA
supports IPoE, PPPoE and RFC1483/2684 bridging
encapsulation methods.
If your
WAN Service Type
is
PPPoA
, the DSL link type is set to
PPPoA
(PPP over ATM) to allow just one PPPoA connection over a PVC.
Encapsulation
Mode
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 ZyXEL
Device 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.
