Hi All, bit of an update with my issue. After a few weeks of chasing my tail with still what seems like an interleaved line with no sign of it relenting, I noticed that the BT Wholesale Checker revealed that there was a Bridge Tap on my line.
I went about investigating this further and have made several changes to the setup in my home. I've removed all but one extension socket which is now directly fed from the master. The router was previously terminated to an extension between two other extensions and therefore the final extension could have been considered as a Bridge Tap.
I have also tidied up the wiring to now only use the two blue wires terminated at the extension from the master and have disconnected all other wires. While investigating the Bridge Tap I found that there was very little consistency of wiring between the master socket and the extensions with some wires connected to some extensions and not to others which may have have been causing an issue. The orange wire was terminated at the master but not at any extensions but the white and orange was terminated to terminal 4 at the extensions but not at the master.
I have spoken to BT since I have made these changes who have all but confirmed that there is no fault or Bridge Tap now detected on my line. The online BT Wholesale Checker does not update regularly enough to currently reflect this status change on there.
Reading another forum it also turns out that the attainable rate increasing beyond what is actually attainable may be a bit of a quirk for some lines and cabinets when interleaving is applied and it exaggerates the attainable rate, not sure how common that is however.
My question now therefore is, if I have seemingly resolved the issue, do I have to wait weeks or even months for interleaving to reduce or would the mods now be able to help my forcing a DLM reset seeing as I believe the issue causing the DLM has been resolved?
