Second Line is faster then old line...


[link to this post]
 
Hi guys,

I'm trying to understand this - and see if I can get faster broadband.

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

I had a second line put in my office/garage (new phone number, new line) for business use - with TalkTalk business. the new line comes from the same telegraph pole at entrance to my garden. The new line gets 50mb fibre broadband.

I've tried all the ISPs but all of them say the maximum my line will support is 16mb to 25mb. But I don't understand this - when my new line is getting 50mb. Same garden/same house, but the online prediction tools do say the new line supports up to 50mb.

Both services cost the same price - and now I feel I am either paying too much for the 16mb service, or I could get fasters speeds and aren't able to get them for some reason.

Could someone explain why I cant get the faster speed in my house?

Thanks smile

It may come from te same pole and cabinet however it may be routed from pole to cabinet in a totally different way. The gauge of wire may be different, there may be a lot of noise on the original line ...

Can you get the basic stats for both lines: Up and Down

Attenuation
SNR Margin
Sync Rate
Max Achievable.

And also check the BT DSL checker with the two numbers (if they work) to get the cabinet information.

As you are getting such good speeds on your work line, do you need the residential one too? Why not link the office back to the house and save yourself a significant amount each month.

The 16 Mbps line should be priced as an up to 38 Mbps
The 50 Mbps line should be priced as an up to 76 Mbps service

For TalkTalk residential there is usually a price difference, but some business services have no price differential, at consumer level difference is usually £5 to £15 per month.

The two lines might even be connected to different cabinets.

What would the BT address checker do in a case like that? It cannot give two cabinets for the same address - or at least I have not seen that.

Address might show up twice with slight difference, or just one address entry and two results for the phone lines

Places I know with more than one line - often to an outbuilding, still only show up as a single entity on the address checker though.

My routers (both the same model from talktalk and talktalk business -

House:

Upstream line rate - 824
Downstream line rate - 15192
Maximum upstream - 906
Maximum downstream - 17168
Upstream noise - 6.2
Downstream noise - 7.1
Upstream interleave depth - 1
Downstream interleave depth - 1
Upstream attenuation - 5.5
Downstream attenuation - 25

Garage:

Upstream line rate - 5997
Downstream line rate - 52402
Maximum upstream - 5697
Maximum downstream - 72312
Upstream noise - 6
Downstream noise - 6.9
Upstream interleave depth - 77
Downstream interleave depth - 3029
Upstream attenuation - 2.1
Downstream attenuation - 17.3


So from what it sounds - there are lots of variables between my garage and my house and the exchanges.

Could I request the line be moved to the other exchange or do I just have to accept the speed difference between the 10m distance smile

Thanks again for all the replies smile

That rather looks like the first one is ADSL2+ and the second is definitely FTTC.

Is there a stats line showing "Mode", something like G.992.5 or G.993.2?

My broadband basic info/help site - www.robertos.me.uk. Domains, site and mail hosting - Tsohost.
Connection - AAISP Home::1 80/20. Sync 71288/12440Kbps @ 600m. BQMs - IPv4 & IPv6

The garage is possibly under performing as the attainable is 72Mbps and that is roughly in line with 17dB attenuation although the the 53 down and 6 up suggest that noise is playing a part in reducing speeds. At 17dB I would expect the attainable UP to be in excess of 20Mbps.

When comparing with the house line there is an extra 7.7dB of attenuation - depending on which set you take that could mean anywhere of 25 to 15 Mbps of speed difference. That would push you down to say 25 or 30 Mbps (roughly) but at 17 you are way below that. Again with 6dB margin noise is potentially a problem. that could originate from your house, a neighbour or anything in the road.

Can you test both at the incoming test sockets with nothing else connected?



As for getting changed from one cabinet to another - unlikely even if it is the case. Have you checked the BT DSL checker to confirm cabinet numbers?

If the cabinets are the same, the attenuation difference suggest a different pole to cabinet route and 17dB is around about 500m.


Have you considered my suggestion of terminating the residential and linking the office to house? the cost of a managed switch to get separate VLANs and the cabling would be covered by savings over a few months.

If he is interleaved that would account for the 52 current and max of 72. Doubt he will see 72 until G.INP is activated which could be a few weeks.
