Current arrangement is BT drop cable (5.6mm) into enclosed front porch and from there, attached around wooden door frame and enters inside house by cable being routed through existing wooden window frame. Drop cable terminates in small BT junction box (6cm * 4cm). Inside, 2 wires joined by jelly crimps and narrower cable then carries signal to NTE5c Mk2 master socket. All of this installed by BT.
Decision to purchase new front door/window means all cabling has to re re-routed and master socket re-positioned.
I am aware of who should be carrying out the work on the Openreach 'side' of the Master socket but just so that I have an idea of the options;
1) is it normal to have the drop wire terminate in a junction box, why not straight into the Master socket? Is it likely this was something to do with old style BT sockets (i.e. before current master socket was installed?)
2) The existing drop cable is not long enough to be re-routed anywhere sensible in either porch, garage or house and so it needs extending. Does it have to be extended with similar spec BT (5.6mm) drop cable or can it be extended with thinner telecom cable (for internal use)? The join will be made inside the front enclosed porch, so not open to the weather, etc.
3) Can a BT master socket be situated inside of a garage?
4) Can I have a non-Openreach telecoms engineer carry put the work and if yes, does it then have to be certified by Openreach?
Thanks for any guidance.
