Phone line was down for quite some time, broadband not so long as we called in and had the account enabled earlier, we could see it hitting the Plusnet RADIUS so knew that bit was done.
Onto the point, the broadband dropped yesterday and a check today after another outage shows that the upstream SNR margin drops precipitously whenever the phone line is in use.
This is not my set up, the Plusnet router goes into the same Openreach NTE that the Sky Hub did, this is a filtered faceplate installed by an Openreach REIN engineer.
I'm thinking I'm connected to a bad splitter or there's a problem with the jumpering in the exchange. Thoughts?

I suspect its a fairly common fault but people don't spot it as they always focus on the downstream SNR. If you raise a ticket the likely response will be to increase your target SNR on the downstream because first line support always seem to try that first if you report disconnections. This of course solves nothing as the problem is on the upstream and you just end up with a slower downstream sync. I hope you get it fixed as I would love to know what causes it.

It was fine before Openreach rejumpered the line to the BT Wholesale kit. It's not exactly a huge leap to connect the two.
Losing 15% of downstream sync and over 30% of upstream going from the conservative Sky network with DLM configured for stability to BT Wholesale won't really impress.
Going to try a different router tomorrow to replace the abysmal Thomson TG582n, see if that helps with downstream. Waiting for the broadband troubleshooter to actually work to finish raising a ticket for the upstream.

Having repeatedly asking the support team not to change profiles and telling them this was the result of the rejumpering work hopefully they'll listen.
After a bit of a disaster as far as the initial switch over went hopefully this can be sorted without too much pain. The previous contact with Plusnet customer service was a disaster. Agent talking over me, ignoring what I was trying to say and refusing to escalate the call. When it finally was escalated it was resolved it 5 minutes flat.
After the experience so far with Plusnet customer service and indeed BT Wholesale our relationship may be a very brief one.

Dives to sub-6dB when the phone line is picked up.

Also can you try the router in the test socket with a normal dangly filter and report the stats again

If you have a look at the first post in the thread you'll see that this goes into a filtered face plate. A filtered face plate that worked perfectly until the line was cut over from Sky's MPF network to BT Wholesale. I think it's fair to say the issue isn't local.

I think said rejumpering didn't go as smoothly as it could have given there was no dialtone for 8 hours.
I appreciate due diligence but DSL filters are a passive device with a low failure rate, there's not much to go wrong. The issue is almost definitely at the exchange.

Sale of Goods Act is calling to be honest. Not fit for purpose. Fine until move to BT Wholesale and Plusnet.
