The thing by your door is the Openreach Cable from your local cabinet or overhead line or however it gets to your property normally concealed behind a plastic cover and grey openreach box then from here the Copper Line Coming into your property which is called a “Drop Cable” is where the Master Socket is connected inside your home.
The local exchange your services come from is where the LLU Equipment is & it can get VERY Confusing to understand all the terminology words trust me.
Think of it as BT/Openreach in the begginning didnt want anyone else using there equipment so they locked it down so only they can provide services to areas in there network and no one else could without there agreement however over time they were forced to allow access to other providers like Cuckoo & Talk Talk & EE to name just a few for competition reasons this is where LLU comes in its the term for line unlocks like having your mobile phone locked to only EE Sim Cards and you cant put a Sky or Vodafone sim in that phone until its unlocked to all networks.
The NGA is also at the exchange as above but just to throw another term into the mix the “Master Socket” where you plug your router and phone into is commonly known as a NTE5c (Network Termination Equipment Version 5C) and they sometimes have an MK model number eg…Mark 4/3 etc. (See below)
The Green Cabinet I like to call an RSR (Road Side Cabinet) which some Senior Engineers call the Telephone Exchange.

Does this make better sense ??.
On very rare ocassions two engineers do show up and thats normally the assigned engineer and if theres a higher issue then the senior engineer or team leader is involved if nearby and thats when head scratching is involved but they should have left you advising that notes will have to be sent back to Cuckoo advising of any issues to look into further.
Looking at your screenshot however I can see one issue straight away.
Where it says PPP Type that states its PPPOA where the Cuckoo Network uses PPPOE so thats why the speed is low as its trying to connect on ADSL & Not VDSL (Fibre) so this needs changing to even attempt to start linking up correctly.
If your quite confident with the web control panel with logging in as stated above I can tell you how to change this over and I hope it starts the link up on your line…no promises mind you.
