- WHY TO USE - If your phone does not fit the telephone plug, phone jack wiring may require a phone adapter. The RJ-11 is often considered the international standard because it is such a commonly found phone jack. If telephone sockets are not compatible with your phone, an analog telephone adapter may be necessary. There are two types of modern British Telecom plugs in common use for connecting telephones, the 431A and 631A. All fit any right-handed "Type 600" telephone socket.
- CONNECTION – This Keple adapter is made to connect BT telephone plug pins 2, 3, 4 & 5 to RJ11 socket pins 2, 3, 4 & 5 respectively. It is intended to connect phones with an RJ11 plug to a BT telephone. It is also suitable for connecting a dial-up modem to a BT socket using a four-wire RJ11 - RJ11 lead.
- HOW TO USE – This Keple British Telecom Adapter is easy to use. Just plug this converter to the BT socked mounted in the wall (marked usually as Openreach BT). Then plug your telephone cord to the female RJ11 jack in the adapter. That is it. It is ready to use now.

## Questions & Answers

**Q: Does this fit a standard Ethernet cable or is it the smaller phone line (same shape) cable?**
A: It fits a normal Ethernet cable, but in my experience it’s the smallest one. There is one larger (can’t remember the number).

**Q: Does this fit the old BT sockets as i gather they changed about 20 years ago but mine is older?**
A: I am not sure. I bought a cheep phone and that adapter. The phone does not work. Not sure if its the phone or the adapter. BT is normally quality guaranteed. The house phone really a novelty so I needed chased it up. Not sure if this is of help to you.
