More profile stuff

[Rainmaker]

Hi guys,

I submitted a ticket to James yesterday having been stuck on a 2 meg profile for the first 10 days of my ADSL24 service. He duly filed with BT, and I turned off my router last night (in day 11) and left it off to see if it would help.

I woke up this morning, and did a BT speed test. My profile was still set to 2000k, but my throughput was 7,000k/sec! :D

However, I just checked my router stats, and for the first time in two years of living here I am synced at less than 8128 (or whatever the max is lol). My SNR has gone up a full dB as well. They are now:

Statistics Downstream Upstream
Line Rate 8096 Kbps 832 Kbps
Noise Margin 15.3 dB 11.0 dB
Line Attenuation 19.0 dB 9.5 dB
Output Power 19.8 dBm 12.3 dBm

BT should be onto this tomorow/tuesday, as the profile is still showing 2000k. However I was just wondering why I'd started syncing lower? As I said this is the first time in two years (and three ISPs!) I've not had full sync. Also, why has the SNR gone up from 14.5 to 15.3 (that's a good thing though, right?)?

Thanks in advance,

Lee

It could be that BT have turned on Interleaving as part of the diagnosing process (to see if it makes any difference)

This will go back to FAST mode within 48hrs and the 8128 will return...

SNR is signal to noise ratio - I think a higher SNR is better as it means the signal is higher then.

On ADSL Max as the SNR will always be low as more speed = lower SNR. The default SNR level on Max is 6dB unless you have a really good line, and then the SNR will be whatever is left after syncing at the full 8128.

Thanks again, James. You were right (of course :D ) - I just checked the line stats and it does indeed now say interleaved (rather than the usual "fast"). Hopefully they'll have it sorted soon.

On ADSL Max as the SNR will always be low as more speed = lower SNR. The default SNR level on Max is 6dB unless you have a really good line, and then the SNR will be whatever is left after syncing at the full 8128.

So, 15.3dB means the ex-BT engineer did a pretty good job on our hardwired extension? :cool: Thanks again for the ridiculously prompt replies - you should start your own ISP!.... Oh, wait... :p :D

Final update. Stats no longer show interleaving on (back to fast), and the BT speed tester shows:

Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 7150 kbps
DSL connection rate: 832 kbps(UP-STREAM) 8128 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 6450 kbps

That'll do me :D
