G.fast ordered

I have finally ordered G.fast 160/30 and see how it goes from there. Not Zen Internet but different ISP. Openreach engineer come to my property to install new line and G.fast 29th July am slot.

My new ISP will be CIX in here: https://www.cix.uk/broadband/gfast as they say it will be openreach managed install with Huawei MT992 Openreach modem as I have to use my own TP Link VR2600 Wireless Router.

How long do I need to wait for new telephone number data to come up? There is no data available for this number. This could be either because it is not a BT line or it is a new BT number that has just been provided. Most new numbers will appear on the checker 24 hours after BT has installed the line

Within 24 hours of the line going live.
Not a minute before.

The order is now cancelled. Because of very poor estimated by CIX saying my line only support by this estimated by BTw.

Down: 101 - 114.2
Up: 9.1 - 12.1

Look like Zen are right spot on did warned me my g.fast line will only get around 114/9. Pointless from VDSL 80/20 to G.fast 114/9

Zen and CIX are both buying the same product from BT Wholesale, talking to the same BTW systems, so will report back the same information.

I'm surprised they'd even let you order it. It's now only supposed to be available to people who have estimates of 120M and above.

I have to ask ADSLMax whether he truly did place an order or was just having some fun teasing as all

His dramatic and volatile life involving his Internet connections is actually better than most things that are on TV at the moment

Jackanory used to be on the telly.

Crackanory sounds more apt

Why is zen and cix saying I would get 114/9 but Cerberus checker say I can get it for 175/21 for g.fast? How can other isp say I would get 114/9 but I wouldn't believe this until Cerberus say my line can do 175/21? Who tell the truth? I have fired off email to openreach to enquired of why some isp's say I get low on g.fast but cerberus seem look fine for 160/30 product when it say I can get 175/21? I don't mind upload of 21 but the download of 175 for these product 160/30 is much twice as FTTC 80/20 to 175/21. But I don't want to order it and later get activated on the line for just 114/9 as I would lose lots of money and stuck on 12 months contract etc.

Because the A/B figures are given to the providers and how they interpret them is down to them

ok but both next doors to my house the g.fast speed 227/35 and 246/38 compared to mine are 198/29 but openreach email say my property should be 227/35 (same as two next doors at 231/35 (before was 330/50) so I do trust that four houses by mine are like this way:

House 1: 231/35 (two next doors on the left side) House 2: 227/35 (next door) House 3: 227/35 (mine) House 4: 246/38 (next door) House 5: no g.fast (two next doors on the right side)

https://i.postimg.cc/19X1bkhB/g-fast-speed.jpg

I believe all four houses should have similiar speed estimated for g.fast between 246 and 227 for downstream and between 38 and 35 for upstream.

So if you want to find out you order, let it go live and cancel if speeds are below estimates i.e. use Ofcom Broadband Speeds Code of Practice and make sure the ISP has signed up to it.

Which ISP have that?

The middle one in the photo is yours?

Look carefully, you'll see the low end of the 'B' range is 114 down / 9.4 up. This is exactly what Zen and CIX are telling you.

It seems that Zen and CIX have decided to show you the lowest likely speeds, so that you may be pleasantly surprised if you get higher - rather than telling you you'll get faster, and you kicking up a fuss when you get less.

G.Fast is *very* sensitive to the exact line conditions. This is because it avoids the lower frequencies used by ADSL and VDSL, and uses only higher frequencies (which are affected more by line losses and line imperfections) and estimates are very rough indeed.

Anyway: your estimates are lower than your neighbours. Who cares? An estimate is just an estimate. It won't make two hoots difference to the *actual* speed you get - the modems will negotiate the fastest speed they can achieve given the actual line conditions. Openreach could increase your estimate to 227 and it wouldn't change the speed that G.Fast works at (*). The only way to find that out is to order it and see what you get.

(*) It may however increase your handback threshold, which is the speed below which you can report a fault.

yes the middle photo is mine! I have to find ISP who have signed up to Ofcom Broadband Speeds Code of Practice not sure if either CIX or Zen or Cerberus have signed up to this?

But I thought If it was 114/9 then surely BTw will removed this g.fast checker off because of below minimum 120Mbops for G.fast by Openreach who no longer sold with a minimum of 100Mbps or above for G.fast service.

Expand first accordion to get the short list

I can't find G.fast via Sky website, is there any link there?

They don't sell it yet.

The rumours on the community forums are it will be in the next couple of months now that details of the new G.Fast hub they will be providing with the two Ultrafast products is now out in the public domain.

It would be interesting to see what speed range Sky will give. Their new internal checker seems to be based on he lowest values of the A/B ranges.

Do you know how long your D side is?

I doubt i'll ever see G.Fast a) I'm on a Huawei all in on one cab b) my D side is 185m.

Dawley does have G.Fast, just not any cabs local to me yet.

Sorry but what is D side mean?

D-side is copper between the PCP cabinet and your house. E-side is copper between the PCP cabinet and the copper exchange.

(D = Distribution, E = Exchange)

As the others have said, it's the length of copper from the cab to your house.

I had a line fault recently and asked the Openreach engineer what the D side length was. His box of tricks and the line route maps he had available confirmed the length.

He wasn't trained on G.Fast but said as I wasn't getting full line speed on FTTC, don't expect headline speeds on G.Fast.

In reply to a post by candlerb:

(D = Distribution, E = Exchange)

Which might be the meaning in Openreach-speak, but would not have answered his question .

My D side is 142m and E side 1667m and line length 248m

Your line length and D-Side are essentially the same thing.

It could be argued VDSL2 line length includes the tie cables, while the D-Side does not.
Your tie cables are not 106m.

Where do you come up with 142m for your D-Side?

Come to think of of, where did you pluck the 1667m E-Side figure? That's a very exact figure for a rough guess.

He mentions elsewhere, that an Openreach engineer showed him the results for his line using the �Magic Maps� app . This will provide exactly that kind of info*.






* it should be noted that the detail this app provides is always a guesstimate, and often clearly wrong

Just my wild guess of using this via google map. I found nearby DP in footway to next two doors with smaller GPO box there in their front garden photo here https://ibb.co/dQ3vmV2 (neighbours has approved and accepted of this photo taken. This house get 330/50 on G.fast)

Photo here of nearby DP pathway https://ibb.co/pZHrfZh

Been look into my outside cupboard (locked) and can see small GPO and I unscrew and took photo of it and screw it back on without touch these. Maybe this one is issues with G.fast low speed? Photo here: Screwed secure: https://ibb.co/7Cm8G9Y and Unscrewed GPO box: https://ibb.co/2dz7PYH (these seem lots of wiring on it with all different colours) my house got 4 master sockets (hallway, living room, two upstair bedrooms)
