The heading of your link is "How is BT Infinity installed (engineer installation)?"
That used to be the only way it was installed. The default now is self-install
- they send a Home Hub with a dangly filter and a couple of cables or so. With very easy instructions.
Have you/they specifically ordered an engineer install, or just "ordered".
The filtered ADSL NTE5 will work but the latest VDSL2 filters are better. The "back-ending" that worked for ADSLx could very well be far from good for FTTC (VDSL2), which is a far more delicate beastie when it comes to home wiring.
Be prepared to have to alter the wiring if the speeds are bad. Several of us can help, once given a clear description of what has been done.
Importantly, is there any star wiring, and is this now the actual master, or are there two, or is the master remote and the NTE5 in use has had its guts removed so is just a fancy extension socket? How many extensions in total are there and how are they connected to what?
Are ring wires (Terminal 3) connected anywhere?
