* Two components need to be removed, and it's recommended to remove a third one. The components to remove are labelled PS1 and PS2 on the circuit board - they may be orange in colour, and can be removed by unsoldering or mechanical destruction. It's optional to remove the resistor labelled R6, the VDSL SSFP doesn't use the bell capacitor in the NTE5c - it provides its own bell capacitor (labelled C8). R6 connects the bell capacitor to the telephone socket, but we're now using the telephone socket as an input from the ATA and so R6 isn't needed and might cause confusion.

Reassemble the VDSL SSFP and install it on the NTE5c. One can now simply connect the ATA phone socket to the phone socket on the VDSL SSFP with an RJ11 plug to BT phone plug lead. It doesn't need to provide a bell capacitor. A lead from an old modem (pre broadband) may be ideal.
