Chapter 5 Broadband The following table describes the labels in this screen. Table 6 Broadband: Add/Edit: Routing Mode LABEL General Name Type Mode WAN Service Type DESCRIPTION Enter a service name of the connection. The interface type used by the ZyXEL Device is ADSL. The ZyXEL Device uses the ADSL technology for data transmission over the DSL port. 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. Select the method of encapsulation used by your ISP from the dropdown list box. This option is available only when you select Routing in the Mode field. ATM PVC Configuration VPI VCI DSL Link Type The choices are PPPoE, PPPoA, and IPoE. VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a virtual circuit. 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. 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. Encapsulation Mode 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. Select the method of multiplexing used by your ISP from the dropdown 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. P-2601HN(L)-F1 Series User's Guide 71
