ADSL Filters ??

Dave_C_2

To summarise, for best results, you should:

1. Plug an ADSL filter into the BT telephone master (or extension socket) using the BT 631A plug.
2. Plug the telephone into the telephone socket in the ADSL filter
3. Repeat steps 1 and 2 for all telephone extensions in use. including fax machines and sky boxes etc.
4. Plug one end of the RJ11 to RJ11 lead into your router and the other end into the ADSL socket of an ADSL filter in step 1
5. Better results if the ADSL filter is NOT on an extension socket

Ideally do not connect your router using a BT631A to RJ11 lead. See my later post.

There is absolutely no problem whatsoever for the telephony side of things connecting your router using a BT631A to RJ11 lead. None whatsoever. The router always connects direct to line without filtering even if you use a filter. The filter is on the telephony side. Only the ADSL router gets upset if it connects to the line through the BT631A side of a filter.

I think you guys mean RJ11, not RJ45

I have a Rj11 to BT phone socket cable.

I know it's been asked already, but were you using the RJ11 to BT (BT631A) adapter/cable as well as the ADSL filter?

You are quite correct. Brain fade on my part.

However the RJ11 to BT631A lead was required in the old days of dial-up. The concern is that the pinouts vary and the router may not work. Obviously not the case with the OP.

It's counter productive if you have the phone and router plugging into the same socket as you need a splitter. The filter (that you need for the phone) does that for you.
