DESCRIPTION
Enter a service name of the connection.
Select an interface for which you want to configure here.
ADSL: The ZyXEL Device uses the ADSL technology for data
transmission over the DSL port.
EtherWAN: The ZyXEL Device transmits data over the Ethernet WAN
port. Select this if you have a DSL router or modem in your network
already.
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.
This field is available only when you select Routing in the Mode field.
Select the method of encapsulation used by your ISP.
• PPP over Ethernet (PPPoE) - PPPoE (Point to Point Protocol over
Ethernet) provides access control and billing functionality in a
manner similar to dial-up services using PPP. Select this if you have
a username and password for Internet access.
• IP over Ethernet - In this type of Internet connection, IP packets
are routed between the Ethernet interface and the WAN interface
and then formatted so that they can be understood in a bridged
environment.
VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define
a virtual circuit.
This section is available only when you select ADSL in the Type field
to configure an ATM layer-2 interface.
The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.
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.
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.
The encapsulation method of multiplexing used by your is LLC/SNAP-
BRIDGING. In LCC encapsulation, bridged PDUs are encapsulated by
identifying the type of the bridged media in the SNAP header.
