No.    In the text accompanying that image there is the sentence --

My thoughts were that because the pair connects directly to that RJ11 socket, that it would electrically be exactly the same as if it were a telephone socket.   Is that not the case?   

[burakkucat]

It is actually an RJ45 socket and you are perfectly correct -- that face-plate is just an adaptor, BT 600-series plug to RJ45 socket.

However if you fit one of those face-plates, I presume you would use that socket to plug in the patch lead to connect the modem (or modem/router). In that case, how would you propose to connect the resistive shunt?

You have funds!

I don't have one to hand to examine, but I was assuming they would be similar to the BT part with a PCB in the back linking conductors from the plug to the socket, if so then that would be where to solder the resistor.

Ah, in that case then "yes"!   

Originally I had no idea that you intended to take the face-plate apart and presumed you were hoping for IDCs on its reverse . . .

When a resistor is on the line, what happens when a call is received? Does the resistor lower the incoming voltage/current?

It will have a miniscule 'shunting' effect on telephony, which will not be discernible.

It might perhaps have an effect on ADSL by causing impedance mismatch if on the line side of the filtering, which is why I recommend fitting on the telephony side of a filter - but maybe I'm being over cautious.

Some of our resident gurus may be able to throw more light on the matter.
