Does anyone know what this brown box is on my phoneline? The wire on the right comes directly from a telegraph pole outside, through hole in wall and into the brown box. The wire coming out left of brown box goes into the phone socket box.
Which of these would be the demarc point and would I be likely to see any improvement in speed if one or both where removed and replaced with a new socket seeing as they are both very old? The bell wire is already disconnected.
The brown box says "British Telecom" on the front and doesn't seem to have any other markings. The telephone socket just has a "T" with circle round it in the bottom right corner.
Thanks for any help.
