OR currently unsuccessfully trying to fix my line

Hi
My line at best achieves 15 meg as I am a mile from cabinet, however for last 3 months I been struggling to get 6 meg down, Openreach are currently here and a lot of headshaking, tutting and sighing is occurring.
The upshot is that � you got a 30v battery on that line there m8, that�s what you got.� I am guessing that is not a good thing and I don�t win any prizes for that, how bad is it, what is it and how will he fix?
Many thanks

A battery contact fault is when your line is picking up the voltage from another line ....

This is usually caused by water ingress in the network somewhere. Often goes hand in hand with a poor connection at the same point (an HR fault).

Battery faults can be measured approximately using the RFL bridge test on the engineers JDSU/Exfo tester .... this will give a rough idea, but can be hampered by a variety of issues I won�t bore you with.

What it needs is diligence and legwork from the OR bod.

He *may* be lucky if he tries a TDR and see the HR.

Hi
Thank you for your in depth reply. he has kind of fixed it and I am now getting 9+ meg, ho where near the 14-15 I used to get but at least an improvement.
OR Engineer said he found fault an managed to find another pair to connect to

If literally just fixed in the last few minutes, there may be more speed to be clawed back after a DLM reset once repair marked as done.

Hi
Thank you all, they had two attempts but now resolved.
Best wishes

Back to 14-15Mbps?

Hi
Thanks for resply, no more like 10meg, they "pulled through another pair" and also found water in the connector box.
Thanks

Hi
Ok, after two visits from Openreach tech they got my fttc up from 6 meg back to around 10meg, not the 15meg it used to be.
Net even two weeks later I am now back to 4meg download. I am wondering now whether kist to change back to ADSL (much cheaper) or even get rid of data altogether on this line. As previously mentioned my other line has data at about 14 meg (same house, same cabinet).

out on interest, what are your line stats and upload speed with it being a FTTC fault?
My old copper line has FTTC on plusnet as a backup for the FTTP installation,
but the FTTC line can do 18-22Mbps down and .2Mbps yes .2!
So interested to see your line stats if poss.
