Sorry to re-open this, but I would appreciate someone 'wot nose' advising on the length of telephone wire in use v. the loss of signal.
If I can shorten the actual distance the signal has to travel on untwisted wire could I expect an improvement in speed or does ANY untwisted run degrade the signal regardless?
I should advise that progress is going to be patchy on this issue for me as Mrs B has some significant medical issues which are taking my focus.
