Can anyone offer some clarification on setting exact dial speeds and how this relates to the various lines offered by BT, Virgin and Telewest?

To clarify, I have serviced dozens of dials, which I have set by eye and tested on my home Virgin (formally) NTL line. I have never had any problems, but I am told that this is not good enough for some exchanges, particularly Telewest.

I have also been told about a ‘Lab-line’ tester. Does anyone know how useful/necessary it is, where I might source one and what sort of costs are involved.
