question: public static boolean validSystemNameConfig ( String systemName , char type , AcelaSystemConnectionMemo memo ) { if ( ! validSystemNameFormat ( systemName , type , memo . getSystemPrefix ( ) ) ) { return false ; } AcelaNode node = getNodeFromSystemName ( systemName , memo ) ; if ( node == null ) { return false ; } int bit = getBitFromSystemName ( systemName ) ; if ( ( type == 'T' ) || ( type == 'L' ) ) { if ( ( bit < MINOUTPUTADDRESS ) || ( bit > MAXOUTPUTADDRESS ) ) { return false ; } } else if ( type == 'S' ) { if ( ( bit < MINSENSORADDRESS ) || ( bit > MAXSENSORADDRESS ) ) { return false ; } } else { log . error ( "Invalid type specification in validSystemNameConfig call" ) ; return false ; } return true ; }
target:  Public static method to validate Acela system name for configuration returns 'true' if system name has a valid meaning in current configuration, else returns 'false'
