You may have a point although he does say in his first post that the house line is fibre and that ISPs have suggested it can only support 16 to 25 which is above the ADSL2+ maximum.


There are also oddities on upstream attenuation 5.5 and 2.1 dB. For the garage line with 17dB down - 2.1 seems a litttle low. On my line I see a nominal 16dB which if I drill down givesD1 at 11.2 and U0 at 4.2.


Edited to correct 16 to 15 which should have read 16 to 25

Potentially - and it could well be noise driving that. And if it is noise, it could be affecting the original house line even more.

The ADSL2+ maximum is 24 Mbps

That should have said 16 to 25 - now corrected. And 25 is above the ADSL2+ maximum.

Sorry, I don't see what you're getting at. To me, it looks like ADSL2+

In my house, I get 16mb fibre broadband with TalkTalk.


I've tried all the ISPs but all of them say the maximum my line will support is 16mb to 25mb.

So, the ISPs say 25Mb which would not be ADSL2+, And the OP believes he has FTTC. Then look at the attenuation - I would expect Up to be around half of Down = so 25 Down would be 12 up with a spread from 10 to 15 maybe. 5.5 is well below.

We need the two Modes.

Single on address, but are the telephone number lookups specific to each line or always a total match?

Two modes needed, and verify that a telephone works (i.e. ensuring garage line is not scrapping by with one leg disconnected, and feedback to checkers has taken this into account)

Good point re the phone line working on the slow one.
