I am using the test socket, i dont have a vdsl master socket yet, so using two micro filters so the broband is split at the master and not sent to the 5 internal extensions. The are 4 sperate wires going to the extensions, do i need disconnect some which maybe the bell?

Drove past the CAB that serves me and I noticed it has had a new side unit added to it, any ideas what it is for?

Probably an extension for additional line cards.

Not G.fast as they are added to the side of the PCP.

Agreed, it looks like a Huawei 96/128 cabinet with a box on the side.

Maybe BT thought a smaller cabinet was be fine for that area, but to then realize it wasn't, hence the extra box.
