Paging - Same as 13, except that the notification service is a Paging System. The phone number of the Ultimate Recipient is sent as a parameter in the URL specified by the client. There is no subscription object created. Printer Description attribute is added that the System Administrator can configure. Only Printer events that stop the device are sent by calling the indicated number.
Printer attribute as well, so that the event can be configured.
I didn't want to clutter up the presentation with these variants.
