Hi pstoian,
In order to download configs, you don't need config change templates but device templates. The one referred above (Alcatel 7210-M-1.3.6.1.4.1.6527.6.2.1.2.2.1.ConfigMgmt-Commands) should work for your devices.
If you have NCM 7.4 connected to the Internet, then you can import this template directly from the web console.
Go to Settings -> NCM Settings -> Device Templates:
Assign the template to the devices you want:
