Fibre Training Period

Hi,
Had erratic speeds for a while, actually line is over 2 months old, I moved as old ISP could pot resolve.

The new one is saying it can take up to 14 days for the line to stabilise?

Then they are fibbing. If the line tests OK, and it’s set up correctly, then what you get is, bar a few nuances, what you get.

for partial fibre internet - fttc up to 10 days for it to settle down, with fttc the line is constantly monitored for line condition changes.

for full fibre internet - ZERO.

Thanks, it is FTTP, thought that might be the case, just wanted to double check.

Its likely they are just following scripts. No provider is going to expect an end user to get the difference between FTTC/FTTP and its just easier to train Tear 1/2 support to say the same thing.

(I've seen the same thing in manuals for products with Li-ion batteries - tell you to fully charge the product for several hours and run it down to zero before recharging. Perfect for NiMH but really bad idea for Li-ion. Thankfully that is less of a problem now but was common for years after Li-ion was standard.)

Who is the offending ISP?

The 10 days has only ever been an ADSL thing.
FTTC is adjusted by the DLM from the second it goes live and it never stops adjusting.
There's nothing written anywhere that says there's a 10 day stabilization period on FTTC and there never has been.

ISP's just continue to use the 10 day / 14 day thing as a cop out to shrug off new customers who complain.
By the time 14 days are up, so is your cooling off period.

Edit: the 10 training period isn't even just an ADSL thing. Specifically it's a BT Wholesale ADSL DLM thing.
Sky and Talktalk ADSL DLM don't have the same 10 day training.

It's a cop out and providers shouldn't be aloud to shrug users off like that.

The OP has FTTP where there isn't even a DLM and his provider (who has never ever had a 10 day training period on ANY of their connections) is plucking "14 days" out of thin air.

That's correct as Engineer told me on FTTC/G.fast there is no 10 days training period. DLM take control of it on the day of new service activated. DLM is just doing it own job 24/7/365 to adjusted it, most line (stable one) DLM just leave it alone as it on day one of new service.

Look up😉😉

Whilst there is no specific period on FTTC it does make sense that it takes some time for DLM in some cases to find the balance. If it isn't good on day one DLM will hopefully kick in and improve it over a period of time. That period of time is dependent on the characteristics of the circuit. But, it makes sense for an ISP to say "please wait x time for the DLM to settle the line to a stable level". The value of x is debatable but as ADSL had 10 days it also makes some sense to use the same figure so as not to confuse staff or customers.
