Step 1

You'll need to download and install the Windows 2000 SpeedStream 3060 driver from the support section of Efficient Network's website.  Once installed, you'll have a new 'ATM Connection' icon in the Network and Dial-Up Connections folder.  This ATM Connection must still be edited to create the ATM circuit portion of the PPPoA connection.  The installation also installs the drivers for two other connection methods, neither of which are important to a PPPoA connection.  Additionally, the Efficient Networks icon that is installed into the System Tray does not apply to the PPPoA connection you are about to create and may be safely removed.  (If you do not know your VPI/VCI pair, you can use this program to auto-detect the pair before you remove it; there's no need to leave this program running as it will always report it is disconnected once we edit the 'ATM Connection' for PPPoA.)

Since the driver installation program does not create a Dial-Up connection for the PPP half of the connection, you'll have to manually create a new one.  (If you don't have a modem, you'll have to pretend you do, just pick a bogus modem in order to create the Dial-Up connection.  Silly Microsoft.  You can delete the bogus modem later from the Modem control panel without affecting your DSL connection.)  Once that's done you'll have something similar to that pictured (figure 1), with an 'ATM Connection' and a Dial-Up (see the little telephone?) connection icon--I re-named mine to 'DSL Connection', but you can call it whatever you like.

(Figure 1)

Step 2

 Access the properties for the 'ATM Connection' and unselect everything, leaving only the 'ATM Call Manager' option selected (Figure 2).

(Figure 2)

Step 3

 Access the 'ATM Call Manager' properties and select to 'Add' a new permanent virtual circuit, you should see a screen as in Figure 3.  Enter your Virtual Path ID (VPI), Virtual Circuit ID (VCI) and ATM Adaptation Layer method.  Choose the 'PPP/ATM Client' option from 'Aplication type' field and select the 'Match only to applications calling this address' option.  Selecting the calling address option should automatically fill in all those zeros, but it doesn't really matter what call number is in there as long as the Dial-Up connection number we're about to edit matches this number.  I simply selected and copied the zeros into the clipboard.  Don't forget to hit 'Ok' to save the changes.

The Name field can be changed, but always reverted back to <unspecified PVC name> in my tests.  I used the 3.1.0 drivers, perhaps the newer 3.2.0 drivers correct this problem, I'll try it myself soon enough.

Unless you know what you are doing, stay out of the 'Advanced' area.  I'll try to explain the advanced options in a later revision, but they are unimportant for this simple exercise.

Step 4

 After you've entered your VPI/VCI pair, you should see your pair listed in the previously empty 'Permanent virtual circuits' page (Figure 4).  That's it for the ATM portion, click 'Ok' until you return to the 'Network and Dial-Up Connections' window (Figure 1).

(Figure 4)

Step 5

 From the 'Network and Dial-Up Connections' window (Figure 1), enter the properties for the bogus Dial-Up connection you created in Step 1.  Unselect everything except a single instance of the 'SpeedStream 3060 Miniport ATM/ADSL Adapter' and enter the calling number from Step 3 into the 'Phone number' field--remember, the numbers must match exactly.  Unselect the 'Use dialing rules' option.  The default options for the other available tabs in the properties for this connection are satisfactory by default, there's no need to change them.  Click 'Ok' to save your changes.

Your PPPoA connection is now ready to go, just double click the Dial-Up connection icon to enter your username/password and viola!
