This is what i mean by a PSTN, and there is no slack in the wiring to fit a NTE5. I was hoping that i could simply replace the extension socket upstairs which is the only socket in the house.
I want to fit an iPlate to (hopefully) improve my broadband speed but I do not have a BTNE5 socket. I do have an old PSTN line jack just inside the front door, from which a line is run up stairs to a standard line jack. Can I replace the standard line jack with a BTNE5 or do i have to replace...
