80/20 Predicted Speeds vs Actual Speeds

Hi Guys,

80/20 was activtaed last night on our broadband and was wondering if you guys could answer a few questions for me.

Here is what the Broadband Wholesale Checker says:
Our test also indicates that your line currently supports a fibre technology with an estimated WBC FTTC Broadband where consumers have received downstream line speed of 55.1Mbps and upstream line speed of 13.2Mbps.

Here is what speedtester.bt.com says:
Download speedachieved during the test was - 44.15 Mbps
For your connection, the acceptable range of speedsis 12 Mbps-46.75 Mbps .
Additional Information:
IP Profile for your line is - 46.75 Mbps

Upload speed achieved during the test was - 6.09Mbps
Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps

Plusnet Profile:
Current line speed: 20 Mb - This seems a little odd??

I was always under the impression that the broadband wholsale checker is usually very conservative in the predicted speeds, but that doesn't appear to be the case.

Does 80/20 FTTC have a 10 day training period? I have read conflicting information on this subject. Is it likely my speed will increase the longer it remains connected?

Don't get me wrong the speed is great, just wonering if we are likely to get a bit more out of it.

I think I'm about 500 meters from the cabinet, maybe less.

Many thanks

At 450-500 metres that does seem at little low ... but as both up and down and low there could be a couple of reasons. High attenuation - or high noise levels. Do you actually know that the route you have plotted is the actual cable route? It could be different and there is no easy way to confirm it. It could go 100m past your house before doubling back, or further along the main road before turning onto the estate.

It is unlikely to change by very much in the near future.

We had FTTC installed on Wednesday. There is a similar thread here about speeds which may interest you:

BTW estimate was 49.9 / 10.9. Just run BT Speedtester which is reporting:

Download: 44.54 Mbps
IP Profile for your line is - 46.81 Mbps

Upload speed achieved during the test was - 6.72Mbps
Upstream Rate IP profile on your line is - 20 Mbps

So we are in a similar situation to you where the upstream is quite a bit lower than predicted. That said the speed is great so really am knit-picking here.

I think the cabling is pretty direct although I am only guessing by looking at the poles and BT covers in the pavement.

I did do a a test at speedtest.net which showed a great improvement on the upload.

The engineer seemed to think it was pretty direct, but I wasn't sure just how much he actually knew. I haven't unlocked my modem yet as I didn't want to disturb the line if a training period was still used.

What does the plot look like in Task Manager - Networking when you do a Speedtest.Net and TBB tests? Can you do a screen shot and provide a link to view it at?

I will do one this evening when I get home and report back.

Thanks.

That bit is absolutely correct - don't be tempted to ask them to change it!

With ADSL and ADSL2+ it was always matched to the downstream IP profile (if and when they recieved a delta report), I take it this has changed with FTTC 80/20?

20Mb is a special value that means unrestricted for FTTC, the value is a hangover from ADSL 2+. This will likely be changed at some point at the future, but at the moment, any value other than 20 for an FTTC connection is potentially bad news as it may restrict your speeds.

Thanks for that info kasg.
