The system interprets shorts on the analog line as low digit numbers like 101,111,123,120. These rooms are getting Crank calls/Phantom ringing. The system will also interpret these shorts as Non existant stations I.E. 113,141 or 191. These will be Illegal numbers and they will be reported to the consoles LDN. And the station number that is shorting out will show up on the console.
