   Well it might work, I have been told that it was possible to get a faulty
filter to work by cutting an internal wire, and that would seem to be a
misconnection that could cause that.

   Both the standard and replacement front panels have a plug at the back
which fits into a socket hidden in the standard BT master box behind. There
are also terminals on the underside of the front panel to allow local
extensions to be connected. The front panel and all, possibly faulty, local
extensions can then be easily removed while testing the BT side of the
system. There is even a notch to allow cable entry. If you report a fault
you may be asked to remove the front panel and plug a phone directly into
the socket behind.
