Yes, it must be that otherwise it don't make sense. OP must be on recently activated TTB LLU ADSL2+ but running on degraded ADSL2 Mode, determined by the DLM..
I dont know exactly but pretty sure that there is no ADSL2 or WBC21 enabled and there are no plans to do it on this exchange. I can not order any ADSL2+ products here.
On the other hand FTTC has been rolled out ish over here and I am able to order if I wanted to trough several providers.
I am on TT wholesale with my provider (so I am told) but when I go on TT website all they can offer me ADSL wise is simply broadband with max 3,8mbps estimated speed.
I dont know. Is it possible to be connected to a different exchange? This area has two exchanges overlapping with coverage. How plausible would this be that I am actually connected to different on? (similar distance away but ADSL2 enabled)
Also I am not on DLM at all. My provider is able to set SNR target manually and it takes instant to apply as well. They set me 9dB target with interleaving off per my request.
All I am not sure about is the error rate whether it will make the trough put suffer in the long run (ES)?
Thanks for replies.
