You have two options Nathan,
You can manually import onto a device in TelnetCE or you can import a series of licenses into a Wavelink License Server on your network and then point the devices to that server in its Emulation Parameters of TelnetCE.
Term-->Authorization to manually import a license
To add a License Server Address to a device, navigate ot the Server Address Field in the Emulation Parameters.
You will also need to download and install the Wavelink License Server on a machine on your network and import the licenses into there.
Term-->Configure-->Emulation Parameters-->"config"-->License Server Address
