AMX NXA-ENET8-2POE Operation/Reference Manual page 151

When a device is known to the control point, periodic event notification messages are sent. A UPnP
description for a service includes a list of actions the service responds to and a list of variables that model the
state of the service at run time.
If a device has a URL for presentation, then the control point can retrieve a page from this URL, load the page
into a web browser, and depending on the capabilities of the page, allow a user to control the device and/or
view device status.
