Having spent years ribbing the IT guys at work about the fact there's only two things to know in their department - how to crawl under desks and how to switch it off and back on again - it transpires that there's a third thing to know... How to 'punch down' Cat 5e cable. I'm fully qualified now!
Seriously though, Alex and Shiraz, if you're reading this, many thanks for your advice.
The house now has data cable to pretty much every room (I think it's called 'future proofing') and it all terminates in this box. Therefore using the patch bay anything can be connected to anything else.
