As you have no phone line an engineer will need to visit to connect an oscillator to your master socket so they can find your pair at the cabinet. Only the fibre part is "engineer-less". That engineer that comes to connect the phone line will install an internal NTE and disconnect the XNTE.
The "engineer install" involves a whole lot more work including connecting your modem to 1 chosen device and fitting an SSFP (MK4 fingered faceplate). They also test the fibre connection to make sure all is fine.
