Hello,
Thank you for the detailed information.
To start with, that is correct that RUT241 devices do NOT support older RUT240 Legacy firmware versions, which had PPP functionality support.
Nonetheless, functionality wise the current RUT241 data connection type is very similar to an older PPP approach and should allow the device to be used in the same situations as with PPP. I.e. data connection type (e.g. PPP) is a backend aspect, describing how a device is communicating with the cell tower.

Could you let me know slightly more details about your solution, in which you want to deploy RUT241 devices, and how these devices are intended to connect to the network?
Maybe you are simply concerned, that without a PPP connection type you will not be able to use devices in a private APN network, or have their mobile IP addresses close to one another? (If this is the case - you should not worry. Such solutions could be accomplished without legacy PPP connection)
