Conversion to SOGEA

I'm currently on a 40/10 FTTC service and notice that I can convert to SOGEA. This will mean my phone number will cease unless I move it to VOIP. Max the line is capable of is given as around 42/43 Mbit.

However as part of the SOGEA transfer process I'm told that:

"A profile reset will be done as part of the conversion, your download/upload speeds may potentially be lower than what they are currently".

What would be the current profile or are these different according to the ISP or supplier, BTW in this case? What would the new profile be, assuming these are pretty standard, and would the practical effect necessarily be slower speeds?

Also, would I necessarily need to have a new line? Whilst the current one is not that good, there are few if any spare and those that are will almost certainly be flaky.

No, the existing line would be used.

Current speeds may be higher as DLM could have reduced the SNR profile, but since you are on 40/10 with a a bit ‘to spare’ it ought to stay exactly as is if migrated to SOGEA

If you aren't being forced to move yet, and you have no reason to want to move, then leave it alone.

They have to pre-warn everyone that it may happen even for a short period of time until the line settles down again but as said by others your max speed is unlikely to be different after the change especially if you're staying with the same ISP.

The profile would be 40/10, 55/10 or 80/20 depending on what package you've bought: 40/10 in your case.

The SOGEA profile will be exactly the same.

This is just a warning that Dynamic Line Management will be reset, and will start evaluating your line quality from scratch. It may choose a lower line rate (with a higher SNR) for a while until it establishes the point where it's stable and safe to go for a lower SNR target. This is likely to go back to where it was before after a few weeks.

When openreach G.fast 330/50 migrate to SoGEA 80/20 as DLM was all resetted to open profile. I get straight away with the same SNR/Interleaved/G.INP already enabled from day one to 30 days now.

So basically they're removing the voice element from the existing copper line and calling it SOGEA. It would be with the same supplier - iDNet in this case - but I'm just trying to get a feel for what I might be getting into.

SOGEA is incidental - it's the VOIP that I'm after since it offers certain advantages. In practical terms since both broadband and phone are with them, I think it better to go for their VOIP offering albeit with a two year contract, since that should achieve the separation of data and voice services without the dance around number portability, possible loss of existing number, new lines and so on.

Once the contract finishes, there is no reason I couldn't transfer voice service to (say) Sipgate, but by then it *should* be a straightforward number port. At that point with any luck I might also be on full fibre.

My main concern is the one expressed on the other thread about VOIP and the emergency services, since the mobile signal is poor at best and non existent for some operators. O2 and Voda are the only two that are usable and even then not all the time. The upshot is that I rely on voice over WiFi for a lot of the time.
