The idea of getting ppp work with network manager is to use the System
-> Adminintration -> Network dialog and setup a ppp connection there.

Then test if that alone works. To test that you have to stop network
manager by running:

 sudo /etc/dbus*/event*/25NetworkManager stop

that should also make your applet disappear from tray.

Then take a look at your /etc/network/interfaces.

If you configured your PPP connection in gnome network admin (like
above), there should be a ppp iface definition somewhere.

Use that name to test on the console like (lets assume the iface name
is ppp-dsl):

# bring down
 sudo ifdown ppp-dsl

# bring up
 sudo ifup ppp-dsl

If that doesnt work, its not supposed to work with network manager in
any case. So take care that it works before continuing.

Once that works start network manager like

 sudo /etc/dbus*/event*/25NetworkManager start

and see if you can connect to your ppp when using the applet menu.
