There is no 10 day training period

Oh ok. I hear it throwing about all over the place. Just wanted to be sure the line was stable before posting anything but if that's the case then i'll get right to posting on Wednesday should no problems arise.

It is BT Wholesale that thinks it has a 10-day training period, but that was/is garbage. As Sky don't use BT Wholesale it doesn't even exist for its customers.

Plus, Openreach DLM operates on FTTC as far as line control is concerned. On BT Wholesale connections BTW calculate their IP Profile from the connection speed Openreach tell them, but that doesn't influence the line itself.

2.2.1 Dynamic Line Management
Dynamic Line Management (DLM) is employed in GEA-FTTC. DLM constantly manages lines to maintain a target link quality (speed and stability). It does this for as long as the product exists.
At provision, the line is put on �wide open� VDSL2 line profiles allowing the upstream and downstream line speeds to run at the upper limit of the product option selected.
On the first day of operation, DLM will intervene if severe instability is detected. Otherwise, DLM will wait until the day after provision before deciding if it must intervene, provided that the line has been trained up for at least 15 minutes during the preceding day.

Openreach SIN 498.

Openreach does have a banding system that they call "Profiles", but it is nothing to do with BT Wholesale IP Profiles. Just another example of BT Group being stupid and using one word to meant two very different things.

Very interesting, thanks for the info Roberto. I imagine the DLM will impact my stats quite severely given my distance, I've got a bad feeling about this whole distance thing but we will see.

DLM isn't interested in distance. Distance, line condition and electromagnetic noise sources determine the connection speed, though DLM imposes a safety margin, the SNR Margin.

Then changes up or down in the noise affect the error rate. But the SNR Margin exists to minimise the effects.

Obviously the longer the line the higher the chance of passing electricity substations, welding shops and so on. But that's a different question.

Good luck .
