## Description

General Information:Telephone cables in the UK typically have a BS 6312 (UK standard) plug at the wall end and a 6P4C or 6P2C modular connector at the telephone end: this latter may be wired as per the RJ11 standard (with pins 3 and 4), or it may be wired with pins 2 and 5, as a straight through cable from the BT plug (which uses pins 2 and 5 for the line, unlike RJ11, which uses pins 3 and 4), thus cables are not in general compatible between different phones, as the phone base may have a socket with pins 2 and 5 (requiring a straight through cable), or have an RJ11 socket (requiring a crossover cable).Specification:Small compact adapterBT 4 wire PlugRJ11 2 wire SocketPin 2 and pin 5 connected on 431A plugPackage:1 x BT Adapter in Plastic Bag

## Features

- 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.
