SonicOS 5.8.1 Administrator Guide
The ADSL interface never unassigned. When plugged in, it is always present in the WAN zone
and zone assignment cannot be modified by the administrator
Click on the Configure icon to the right of the interface entry. You will see a menu with
three tabs: General, Advanced, and DSL Settings. The DSL Settings tab allows you to
configure ISP-specific settings for the ADSL connection.
It displays the configurable DSL fields:
Virtual Path Identifier (VPI)
Virtual Channel Identifier (VCI)
Multiplexing Method (LLC or VC)
The values for these parameters should match the settings on the ISP DSLAM, and are
provided by the ISP. These values vary from one ISP to another, and from country to country.
The SNWL default uses the most common values in the USA. The VPI and VCI settings are
used to create the Permanent Virtual Circuit (PVC) from the NSA2400MX to the ISP DSLAM.
When finished configuring these ISP settings, click OK.
The Ethernet-specific settings on the Advanced tab, even if set, do not apply to the ADSL
module. The Link Speed field in the Advanced tab has a fixed "N/A" selection, since it does not
apply to ADSL. The ADSL link speed can't be customized but is predetermined by the DSL
Provider.
The standard WAN ethernet settings are not affected by the presence of the ADSL module.
