Yes, that is the Openreach DLM, and there is no dispute or even a question about that
. The OR DLM however only controls what happens between the exchange and the cabinet, and on to the premises. There is clearly no 10-day period involved there.
However, I also raised the point that WBC, which Infinity relies upon, also has its own BT Wholesale DLM, which is where the 10-day period does exist for ADSLx, and I assume also for FTTC. Amongst its functions, this DLM is used to control flows through the BT Wholesale backhaul network.
In the case of FTTC though, the mere idea of it setting MSR and FTR figures is laughable, and that is the only thing it does for anything at the end of the first ten days - ADSL, ADSL2, ADSL2+.
Quite where the IP Profile we see when doing a BT Wholesale speed test resides is something I don't think any of us have seriously thought about. I begin to suspect it is purely within WBC and not a feature of the Openreach one. That behaves as per the quote you give.
