One needs an ADSL microfilter of the type supplied with modem/routers over the years. It needs to be of the type where the connection to the line is made with a short BT plug to an RJ11 plug (American style) - i.e. the microfilter has two RJ11 sockets on it, and one BT phone socket. One also needs an RJ11 plug to RJ11 plug lead. Remove the existing RJ11 lead from the VDSL SSFP, plug one end of the new RJ11 lead into the VDSL SSFP, and the other end into the 'line' connection of the microfilter. Now plug the free end of the old RJ11 lead into the microfilter, and ensure the modem/router regains sync. Now the phone socket on the microfilter is connected to the copper pair.
There are a few gotchas regarding the wiring of RJ11 sockets. The VDSL SSFP uses pair 1 (pins 3 and 4) on the connection for the modem/router. I have the odd microfilter where the RJ11 (or RJ14 ?) line socket uses pair 2 (pins 2 and 5) instead
