How to open PPPoE through "Internet Connect"?

I am trying to write a script for reopening PPPoE connection. It seems that many guys have this need, but I found no working script available… I am trying to write:

tell application “Internet Connect” to connect configuration “PPPoE”

but I get “NSReceiverEvaluationScriptError 4”.

If I write only:
tell application “Internet Connect” to connect

or

tell application “Internet Connect” to connect configuration

then nothing happens after activating the application. It is interesting that “disconnect”-ing works quite quickly!
