Guys, just so you are aware (and most of you either will be or know this to be rubbish), but the C line supplier told me that the Spiderbox can only take 4 lines of C line. Now that he has reduced the original 5 lines provided to 4 its working fine. Thats what they told me anyway...and it is working fine now.
Thanks for all your input and help.
Regards
Carl
