The speed differences on similar line lengths is interesting.

Here's a distance-annotated aerial view between my cab and my street. Probably about 400 m. Cabling is no more than 8 or 9 years old so I was expecting faster speeds (and so was the BT Wholesale checker!).

My cabinet is absolutely rammed full though. Consistently no capacity available. Not surprising since ADSL tops out at about 1.5 mbps here!

My property is 38 years old and the telephone cable in my property never change since 1976. The hallway with master socket (old one) was destroyed two weeks ago by BTO engineer (proper engineer) and he cut off half cable behind the master socket terminal wire that comes from the street to the hallway and fitted brand new master socket with MK2 faceplate. Took him to do 40 minutes job to do this.

But, don't forget engineer did told me I am the only person on new FTTC cabinet when they installed my FTTC service as no one else order it yet.

Yes, but that was a while ago. More than likely others are connected now.

I was surprise that my DLM haven't kicked in yet since Feb 13th

You have a stupidly short D-side pair, plenty of SNR in hand, of course it's going to be stable.

because if it was 200m away I wouldn't getting 80/20.

I'm more than sure you would.

Yes - problem is we don't know what the cables in the street are made of, or how many joins or repairs there have been.

In around 2010 I was with BE and getting 18Mbps sync (17Mbps throughput) on ADSL2+ and then my line "died" somehow, constant disconnections even on stupidly high SNR margins. After lots of investigation, a BT SFI was called out who found the wiring in my flat was no problem, and started investigating in the street and in the block of flats. He found some really old joints circa 1972 when the block was built, and fixed those. Then a couple of issues in the street and at the cab. When he'd finished, I had a stable 16Mbps sync, with 14Mbps throughput, but rock solid again.

The SFI let me see the line plant diagram on his Toughbook, so I know exactly the route the wires take out of my road, and its very logical. The exchange is at the end of the road mine opens into and about 1 mile away. My wires basically are L shaped! Using google street view and other mapping sites, I measured the route the wires go from my place to the cabinet, and got 450metres. Others have looked at my attenuation and say 470m.

My wires go past a school, but no industry to get to the cab. They probably have a lot of joints in however, as the rest of the estate around me is a lot older, potentially pre-WW2. (I suspect originally officers houses for the Royal Aircraft Establishment that was the reason for Farnborough existing)

About 6 years ago there was a fault on the line coming into the whole estate. BT's fix involved rerouting the line adding 2.2 KILOMETRES to the line length, dropping about 700 properties' ADSL speeds from about 5-6 mbps to 2 at best.

I did a bit of Google Earthing on the image I linked to. I can only assume that crosstalk is slowing my connection down.

Yuck

It sounds like it. I'm hoping here that people are still preferring Virgin Media who are in the estate, but uninterested in flats.

I would not recommend Virgin Media if your area is on high utilisation

Or maybe if BT's vectoring trialling is successful and they can roll it out everywhere? *please please please* haha

I have no experience with Virgin as I've never lived in a cabled area. It's weird, Virgin advertise how "superfast" they are in cheesy adverts featuring Usain Bolt et al. yet all you see online is endless complaining about 'high utilisation' and ridiculous latency.

I guess ye olde phone line is still the way to go for now!

For you and other's, yes vectoring will help your speed increasing. (no point for me as I am on a maximum over 100+Mbps)

Question is how long will BT going to do it roll out?
