Hi
I've just replaced an original BT extension with a new cable run. The previous extension was made of of lots of old bits of wire with several joints etc. The total run length was about 75 metres and worked perfectly.
I just ran 4 x 80m Cat5e cables using 2 as phone extensions, both buzz!! Any ideas as to why a scrappy old bit of BT wire doesn't buzz and my new shiny twisted pair does?
Ta
Tony
