Exchange fault, DLM and BT Support Activities

Story is, my speed kept decreasing over a few days and was eventually disconnected for most of last Saturday, but was reconnected late Sunday, before BT booked an engineer.

I called BT anyway as it was clearly not right, they identified an issue at the exchange and booked an engineer for today. I didn't get any call or update after the appointment slot so I asked online what has happened and was told:

"they changed the NTE master plate and star cable at the junction box as that was old"

This makes no sense to me as I've only heard of NTE master plate and junction box in the context of within a property, which they did not attend - maybe I'm wrong?

BT Support are adamant DLM is not applied to my line however my router stats beg to differ:


Max:	Upstream rate = 10705 Kbps, Downstream rate = 38772 Kbps
Bearer:	0, Upstream rate = 7200 Kbps, Downstream rate = 27399 Kbps

I'm starting to think they didn't do anything at all. Fault is still "open" but curious as what to do next - wait? escalate?

Re: Exchange fault, DLM and BT Support Activities

looks like all your disconnections have resulted in your conenction ending up in a banded profile.  You need to get your connection fixed and a stable connection before DLM will release banding
