what the difference between TT Business Standard BT OR DLM stability profile and PN OR DLM Speed profile?
I am not sure if TT Business are DLM on G.INP enabled too? As every FTTC are now switching on G.INP by OR (I used to be on fast path for long times over 14 months before OR changing the G.INP.
The DLM and G.inp are implemented and maintained by BT Openreach, So work exactly the same regardless of the ISP (Plus they work at Dslam /cabinet level ) or if it is Openreach GEA which is purchased by TT and Sky and other ISP's where they have LLU kit in the BT exchange either way the ISP has no real control over the connection from cab to master socket apart from the DLM stability profile used
The rest of the ISP's purchase FTTC via BT Wholesale who order from BT openreach
The difference being the back haul/data transit provider BTW or TT ect
Of course if the ISP's network is used for transit then there's no BTW IP profile So max throughput rates can be a little higher
When i said that i didn't know what impact the different stability profiles would have, for those who have G.inp enabled (which would appear to have replaced fast-path)
Dlm may react by applying banding , or setting a higher level of G.inp /interleave, no one seems to know what it's next step would be, but i would say that if on standard or stable profiles that next step would be more likely to occur for most
