Bought for connecting a Brother - MFCJ6910DW - Inkjet Multifunction Printer professional A3 color - 4-in-1 - Duplex - Wifi which can be connected to an ADSL line (but comes with an RJ11 cable) behind a FreeBox 5. As the latter has a RJ11 output, difficult to connect and fax, and telephone.
Nickel operation, not bothered by a mono-block splitter that threatened to block other connectors of the Freebox.
