This adaptor is used on the end of a BT telephone line connection cable to allow it to plug into an RJ11 socket. This is useful for dial-up modems or other RJ11 devices, and prevents the need to purchase a replacement cable.
This adaptor is very easy to use. You just plug the adaptor onto the ends of each cable/socket, and your computer is ready to access the internet via dial-up connection.
Please note: These are new items, but some are slightly scratched / worn as they are old stock.
The adapter arrived by the promised date and it works as expected. I am now able to use a BT phone in India without issues.
My BT phone has an RJ11 socket. However, a standard RJ11 cable wouldn't work since the pins on the RJ11 used in the BT phone are different from the standard RJ11 (2-3 vs 4-5). My ideal solution would have been to get a crossover cable, but I couldn't find it anywhere. So I have a BT cable from the phone and this adapter.
