Perfect and suitable for all configurations
Not visible on the photos, this ADSL filter has, in addition to the RJ11 and Rj45 sockets, internal terminals to which the cable pairs can be connected directly. In addition to the possibility of dispensing with unnecessary connectors and adapters, it also allows - for people with full unbundling - to send the telephony from the ADSL box back to the home telephone network by connecting the telephone output of the box to the J3 socket and the home telephone network to the J4 terminal block.
We would have appreciated it if the instructions (which are not absolutely essential) had been supplied, but they can nevertheless be easily found via a search engine with the model number indicated on the box.
