Physical connection:
Connect the USB cable from the ADSL modem to an Abilis USB port.
Connect the ADSL modem to the telephone line using a standard RJ-11 cable.
Before proceeding with the configuration, make sure you have the following parameters available from your ISP.
| Parameter | Possible values |
|---|---|
| Encapsulation | RFC 1483 or PPPoA (RFC 2364) or PPPoE |
| Multiplexing | VC-Based or LLC-Based |
| VPI (Virtual Path Identifier) | 8 |
| VCI (Virtual Channel Identifier) | 35 |
| IP Address and Mask | static (80.80.80.80/32) or dynamic |
| Login information (only for PPPoA or PPPoE encapsulation) | username: provider_user password: provider_pwd |
The configuration varies depending on what encapsulation type you use.

Abilis supports ONLY the Routing mode (not Bridge mode). |
Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.
| a dev:adslusb-1 | Add an ADSLUSB device (e.g. ADSLUSB-1). |
| a res:ip-3 subtype:dl | Add an “IP over Dedicated Line” resource (e.g. IP-3). |
| s p ip-3 lowres:adsl-1 | Configure the ADSL-1 as the IP-3 lower resource. |
| s p ip-3
enc:rfc1483-llcmux or s p ip-3 enc:rfc1483-vcmux | Configure a LLC-based multiplexing
type. or Configure a VC-based multiplexing type. |
| s p ip-3 vpi:8 vci:35 | Configure the VPI and the VCI. |
| s p ip-3 ipadd:80.80.80.80 mask:255.255.255.255 | Configure the IP address and the mask. |
| s p ip-3 descr:ADSL_RFC1483 | Configure the description of the IP resource. |
| save conf | Save the configuration. |
On a working Abilis, a system restart is required to make the ADSLUSB-1 device and the IP-3 resource running.
