You were getting a downstream sync of 4448Kbps from the test socket on the 24th September, so it looks like you have somehow lost nearly1000Kbps?

Yes caused by internal wiring issues, I can live with 3mb, as I said its a very rural location.

Did your "Engineer" fit a filtered faceplate, and then run all the extensions from the 2 and 5 terminals on the back of that?

To me, that is by far the best way to do it.

Sounds to me like the "Engineer" has just connected all the extensions (maybe removed a star-wired layout) but left you with plug-in filters at all points? Less than optimal, shall we say.

No he didn't, because that is not what I needed him to do.

I'm not sure why you felt the need to put engineer in speech marks, but I can hazard a guess.
