NOTES:
This locking shift must be present if any of the optional IEs following it are  present; 
otherwise, it must be absent.
The ASAI application may either “collect digits” or “supply digits,” but not both. Thus, 
only one User Entered Code IE is permitted in the message.
Not currently used (ignored).
The Specific Event IE is present only when the application includes the User Code IE 
to “collect digits.”
