One better would be for the Virgin line to go to the existing BT 66b, connect their line to the current BT master and install a new virgin socket to which the BT line would be connected, that way if we switch in future it's just swapping the pairs over in the external box.
Even better would be to have a switch in the BT 66B so I can switch which line goes to the BT Master socket literally at the flick of a switch. The closest I could see to this was a BT Switch 2A, but can't find a modern version of this?
Given this must be a fairly common thing for people to have when switching between providers, I'm surprised I couldn't find a decent solution to the problem. Any suggestions? Or is wiring up my own DPDT switch in the BT 66B the best option? Any issues (other than messing with BT wiring not being allowed) with going down this route?
Any advice / suggestions appreciated
