How long is the coiled up black cable, can you take a photo of it and post a link to it?
It might be a cable that goes into the home and right into the ONT, but I thought they stopped that and went back to the old way with the cable from the DP->Manifold->CSP->ONT.
Ours wasn't a Twin Cable, ours was just a black tubing where they then blew the fibre down, then they connected one end to our allocated fibre in the DP and then coiled that up in the CSP, where the next day the second engineer just joint a cable to one of the fibres in the CSP and then connected it to the ONT.
I remember at the time the engineer taking a photo of the Speedtest result, maybe BT were making sure all went well with the install LOL
