ONT BBU melted

following on from my previous post re the fault light on the ONT being lit. As was suggested on here I by passed the BBU and put the power lead straight into the main part of the ONT. when I took the BBU out and opened up the battery compartment, part of the scalloped battery holder had melted and the plastic sleeves had come off three of the four batteries. one of the battery terminals in the BBU seems he have been pushed out of alignment due to the plastic melting? So if you see the same light on your ONT check the BBU.
just waiting on OR to bring a new BBU

Well OR have just been and it now seems that there is no requirement to provide a battery back up. the OR engineer took away the melted BBU so that it can be examined but didnt provide a replacement, just agreed with what I had done, ie plug the o/p of the power supply straight into the ONT

If one kidney fails, we can live with one. Therefore all people with two should immediately volunteer to have one removed should they at some time in the future have a tissue match with someone with none.

The flaw in that is �?

Yeah the BBU, is no longer a requirement apparently. At least the OR bod took your melted mess away for you..

The BBU�s presence was only to satisfy an Ofcom ruling on the ability to use the FVA service in the event of a power cut.

Somethings changed somewhere, and this is no longer a requirement...

Also a handy cost saving for Openreach too.

I understand BT Wholesale will be scrapping FVA at some point in the future (next year?) which might explain why Openreach aren't that bothered about a BBU unit anymore as its primary function is to power the FVA port during a power cut. Good job I politely refused one a couple of years ago

that is what the OR bod said. happened about jan this year. as i have one of the newer ONT which had everything in one box only the lack of some led's gives away the fact that no BBU is now inside the case.

Wholesale never sold FVA (publicly).
Openreach are stop sell on FVA next year.
BBU is no longer installed except from manual temporary process for voulnerable customers.

The BBU only powered the voice ports and fibre anyway, data ports were disabled when running on battery mode (at least on the 4+2).

Retailers are moving towards doing the voice port on their own hardware

Well we had no choice really, our copper line is NOT fit for a phone line due to so many faults on our copper line to a point when it became windy or rained our line would just go dead, and when it did work there was a HR Fault on it, sadly there is no spare pairs available.

So when BT installed our FTTP they also moved our phone line over to it too, we was also charged a £30 cease fee on the copper line, so if we get moved back onto that I will be demanding that back.

So I cannot see them dropping the FVA until all homes have a working phone line.
