81.7. How to configure ADSL connections using USB modems

Physical connection:

Before proceeding with the configuration, make sure to have from your ISP the followings parameters:

ParameterPossible values
EncapsulationRFC 1483 or PPPoA (RFC 2364) or PPPoE or IPoE
MultiplexingVC-Based or LLC-Based
VPI (Virtual Path Identifier)8
VCI (Virtual Channel Identifier)35
IP Address and MaskStatic (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.

[Note]Note

Abilis supports ONLY the Routing mode (not Bridge mode).

81.7.1. How to configure a RFC 1483 connection

Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.

a dev:dslusb-1Add an DSLUSB device (e.g. DSLUSB-1).
a res:ip-3 subtype:dslAdd an “IP over DSL” resource (e.g. IP-3).
s p ip-3 lowres:dsl-1Configure the DSL-1 as the IP-3 lower resource.
