I'm sorry of this isn't really a network sys admins question but I've found that people here usually know their stuff.

I need to make up a lead that goes from my ADSL microfilter to my modem.

Could anyone furnish me with the pin configuration for this, taking in to consideration that I'm in the UK so the phone pin config will be different to the US. [I think that pins 3 + 4 [US] are 2 +3 [UK]].
