What fibre speed should I be getting, based on these figures?

According to BT Wholesale, this is what my cabinet is capable of:

 

                        High	Low	High	Low		
FTTC Range A (Clean)	58.4	42.8	15.8	10.4	--	Available
FTTC Range B (Impacted)	42	22.4	12.2	5.8	--	Available

My router/modem says this is what I'm getting:

 

6. Data rate:	        9995 / 34800
7. Maximum data rate:	14968 / 35939
8. Noise margin:	9.8 / 4.7
9. Line attenuation:	28.0 / 21.0
10. Signal attenuation:	27.9 / 19.8

Given the above, what speed should I expect to be getting?

Re: What fibre speed should I be getting, based on these figures?

looks like you are on infinity 1 and with the estimate from dslchecker I would be expecting 40/10 connection

 

are you using the test socket with a new filter to eliminate your internal wiring as causing a problem

No, I'm not plugged directly into the test socket, it is on an extension socket within a 10 metre cable run from the master socket.

can you connect hub directly with a filter to the test socket without the 10m extension cable as that may be causing the problem especially the standard flat type extension cable

Looks like that is the answer. Plugging it directly into the test socket results in:

 

6. Data rate:	        9995 / 39993
7. Maximum data rate:	19506 / 57298
8. Noise margin:	12.7 / 11.7
9. Line attenuation:	25.5 / 20.5
10. Signal attenuation:	25.4 / 20.0

You should get the full 52M when your line gets upgraded to the new Infinity1 speeds.

that's a lot better   not only has speed improved but noise margin looks far better now as well

Problem is, when I plug directly into the front of the master socket the speed goes down again. I can only get those speeds directly plugged into the test socket.

Re: What fibre speed should I be getting, based on these figures?

then you have a problem with either your internal wiring or the master faceplate or both.  you could upgrade your master to an SSFP mk3 fibre SSFP.jpg

Looks like it's the extension causing the problem. If I plug in a different faceplate then I get the speed back.

 

Maybe I'll need to ask BT to move the master socket? How much so they charge for that?
