Enables you to specify the password scheme to be obeyed by users of the VTScada Alarm Notification System.
- If set to 0, passwords will be unmapped (i.e. only strictly numeric passwords will be accepted by the Alarm Notification System (e.g. 98443)).
- If set to 1 (default), letters will be mapped to numbers as per ITU-T E.161 (i.e. the letters Q and Z map to the numbers 7 and 9 respectively).
- If set to 2, letters will be mapped to numbers as per legacy scheme (i.e. the letters Q and Z map to the number 0).
- If set to 3, both scheme 1 and scheme 2 above will be accepted (i.e. the letters Q and Z and the numbers 7 and 9 map to the number 0). Please note that this scheme is less secure!
By default, the call-out system has been configured to use alphanumeric passwords. If you change the mapping scheme from its default (i.e. if you change the value of AlphaNumericXFormScheme from 1 to 0, 2, or 3), user passwords will have to be re-entered into the system by telephone. See also: ForcePasswordAltIdSync.
