kmashlan: No master filter, but based on the wires on the ground and the "tidy" condition now, they cut out a lot of the mess. It is much simpler now, although all that has been done is to tidy up the connections from twisted wires to proper gel connectors, then covering it all up.
I am OK with this for now as I will go with fibre when it arrives in six months or so. Until then as long as the line is stable - i.e. not crackling or dropping, I am all good.
You are easily pleased - your ISP must love you

Hopefully you'lle get a better fibre install when the time comes.
