Just wondering how you would set up a CSB "without" contacting NC? As far as I know you cannot.
One *could* cut into a local panel, although the phone would ring with a rather annoyed signaller/TC on the other end...
Still need to have the NCO permission prior to cutting in.
Oh yes, according to the rules! One wouldn't dream of cutting in without doing so. Perhaps I should have elaborated - I meant that one could cut in, although unless you contact the NCO, you won't be popular. At least, this is speaking for the station local panels I have had experience with.
