Another Update
Still was having problems, phoned Tech support and they have been today, She was brilliant, It turns out my port was dodgy and she put me on another one and she getting the networks guys to replace the Amp in the cabinet.
She changed an "Isolator" as she said it was the old type and they can break down after a while.
Touch wood all is well and i`m very happy with the knowledge the Engineer had.
Thanks Again
