I know my cable routing very well including the ducting. Accounting for the distance up the pole, the pole to pole centenaries, drop wire to house and internal wiring I am 440m from the cabinet.

At 440m, I am currently sync'ed at 38717 kbps and can get speedtests (BT and TBB Flash) with results of 38000 and above.

The BT Technician got results of: 39.996 Mbps with a max possible of 46.667 Mbps

Surely the 38717 is just the profile (top banana). The 39996 is commonly seen by the JDSU, which will sync slightly lower than the modem itself.

Longest pair showing full sync (so fa,r) was 890m on ducted 0.5 copper

So looking at the comments so far, the cab distance should be within the 30-40mb range. Is this something that I should continue to pursue and try and get someone from BT to sort my speed problems out? There's no way my speeds are as low as 17-19Mbit without something hindering it. Tbh, you can get those kinda speeds on ADSL2+ and it's disappointing that I'm getting them on fibre. It's not even that far off from 15mb which BT would classify as a fault.

Yes, I'd be ringing up, taking the pain, and see if they'll get someone to take a look at it. It *could* be that your D-side is a couple of hundred meters of iffy old aluminium, and thats all that can be done ........ but, maybe theres a fault on the pair, or the modem's duff, or the DSLAM port is knackered, etc, etc, etc.

Good luck, and keep us posted.

Sorry if this sounds silly, but what is the D side? Demarcation side? Would that be the old copper wire outside the house coming from the pole?

It refers to the side of your local cabinet. E-side is exchange, and D-side is the wire to your premises.

Ok quick update.

Had an engineer call this morning saying that he was going to switch us over to a different port at the cabinet and the exchange and then come and test the line. He didn't come to test the line but I did get a call saying that we were switched over to a different port and his work was done. So far I'm not noticing any difference in speeds. Still the same 19424 profile but the guy from BT did say it would take a few hours for it to rise. I'll wait but I've got a feeling it's still going to be the same. Usually from various posts I've read people who are experiencing a slow throughput still have a profile of 38717 or close to it and BT do something on their end to increase it and the throughput goes up to match the profile. However, my throughput *is* matching my profile, just that unfortunately it's at 19424. I'll give it a wait and see, and if it doesn't improve I'll call them back as the case is still open for another few days.

One thing I have noticed however, is that my ping has dropped really low. Before I was getting around 20ms pinging to bbc and around 25ms on pingtest. Now I'm getting 12ms pinging bbc and 16ms on pingtest. So atleast one positive.

You can't predict FTTC speeds on the basis of an ADSL MAX connection, as FTTC is based on distance from cabinet, not exchange.

I've heard that FTTC connections usually vary up, friend of mine had his installed last week. Started at 24mbps and by the end of the week is upto 31mbps.
