So if it is feeding the line back down the cable on a spare pair the extension socket is actually earlier on the cable run the the master? So it runs, cable from outside -> extension socket -> master socket?
Dead simple to convert the extension to a master socket unless the extension is run outside the house or splits off.
So "it depends" - on the current wiring and the amount of flexibilty from the OpenReach installer. Since, I believe, SKYare not paying for the full managed install that BT retail pay OR for the options may be limited.
