In reply to a post by pluralist:

I support the view that ADSL2 is likely to be the best of the three options.

On my previous connections (ISPs) ADSL2 was more stable when the SNM was lowered on my router but that is not possible with the BT router. ATM nothing can be done while the training is on going. I forget whether it is for 10 or 14 days. It was activated on Monday.

The training will normally last 10 days . BT , I believe, only support their own. Equipment . Your speed touch may support adsl2 settings,
The sky setup was from their own llu box in exchange and maybe different than you get on BT line
Bob, has more detailed knowledge and will probably reply

The training will normally last 10 days .

A popular misunderstanding. The ‘training’ is a constant thing, remote monitoring is always looking at how stable the connection is, how many errors, loss of sync, etc, etc.

Thanks
l always learn something from your posts .

A still valid page, (like many on that site), but this page only refers to BT Wholesale-based ISPs. LLU providers use their own line management systems, completely independent of the BTW DLM.

On Openreach (GEA) FTTC the day to day line management is also basically nothing to do with any provider. Openreach give them three stability options at the start of any new connection, (alterable), and the main DLM is Openreach's.

Having said that, Openreach stipulate that all ISPs on the system make sure their internal servers/routers to not deliver data to the DSLAMs in the cabinets faster than the current connection speed. (For fairly obvious reasons).

The BT Wholesale IP Profile is still operative on circuits they control on FTTC, in order to achieve that. The "LLU" providers again use their own mechanisms to ensure it. (There is no such thing as LLU on FTTC. This page explains LLU. Clearly impossible in the tiny FTTC cabinets where there is only room for the Openreach DSLAMs).

Interesting. Thanks
