follows.
Incoming: Limits all incoming calls.
On: Sets up all incoming calls barring.

to make a call that has the prefixed number that you

Bar All: Sets up all outgoing calls barring.
Bar Prefixed: Adds and deletes the prefixed number. (Prefix
also means your 10 or 11 digit number of your choosing)
Off: Cancels all outgoing calls barring including the bar prefixed.
