Thats Ok - as you are probaly already aware your cableing appears to have been wired for dedicated phone use only with one pair connected (blue&blue/white) and 3 spare pairs in each cable (except for the one or two cables that appear to have to have 2 of the other pairs attached to a rj45 to terminal block in your hub)
A sugestion is to convert your cableing to non-dedicated structured wireing both ends of the cable terminated on RJ45s (all 4 pairs terminated) and to make multipule use of a single jkpt, addaptor plugs are used, which are commonly refered to as spliters (Not to be confused with a master spliter), to break out the pairs for seperate use if required or you can use a jkpt for data (1000) and another for a phone.
If you want to keep your existing RJ11s and just add RJ45s for data (10/100) then you never terminate the third pair (Brown&Brown/white)
Any links for the adapter plugs/splitters you're talking about? They aren't the dsl filter you get with modems which splits into a BT and RJ11 Plug right?
Are you saying that i disconnect the single pair already connect on both the panel and the jack turning it back to a full speed gigabit ethernet cable than use your splitters and both ends..?
Would a non terminated pair of wires actually do anything since it's not connected at both ends at all?
Something like this?
