I dont know whats going on hence me asking for advice
I would love to know what a MU fault is as well
Its good I have a planned fix date now, before I was advised it could be anything within 5 working days.
Basically the cord error on my BT handset, usually appears if its not connected to the nte5, so basically its just saying there is no detected phone line.
There is kitz what I think is a junction box near the roof, my line is fed from it, however I have never been able to get it checked by an engineer, they tend to take a look at it and decide to not bother. It seems tho openreach already know where the fault is based on what sky told me, it looks like its under a road somewhere if they need to do roadworks.
