Upgrading from 8 to 20mbps WBC


[link to this post]
 
hi,

received an email from my isp saying my 2 broadband connections will be upgraded to upto 20 meg tommorow, wondering if i will see any increase in speed.

router stats are:

line 1:
Line state Connected
Connection time 2 days, 23:23:11
Downstream 5,504 Kbps
Upstream 448 Kbps
ADSL settings
VPI/VCI 0/38
Type PPPoA
Modulation ITU-T G.992.1
Latency type Interleaved
Noise margin (Down/Up) 5.9 dB / 18.0 dB
Line attenuation (Down/Up) 46.0 dB / 25.5 dB
Output power (Down/Up) 19.8 dBm / 12.3 dBm

line 2

Connection information
Line state Connected
Connection time 1 day, 0:32:20
Downstream 6,048 Kbps
Upstream 448 Kbps
ADSL settings
VPI/VCI 0/38
Type PPPoA
Modulation ITU-T G.992.1
Latency type Interleaved
Noise margin (Down/Up) 5.1 dB / 19.0 dB
Line attenuation (Down/Up) 46.0 dB / 27.5 dB
Output power (Down/Up) 19.8 dBm / 12.1 dBm

the attenuation on line 1 sometimes changes from 47 to 46 db. line 2 generally connects faster as the line is only a year old.

I suggest you have a browse of the Ring/Bell wire and Miscellaneous nasties pages in my Troubleshooting section. Both lines should be getting over 6Mbps fairly easily at the moment.

As for ADSL2+, not too much hope of more frown.

You will see a boost now sure how much maybe 10% max.

ring wire removed from line 1, line 2 has no extentions. both are the newer openreach faceplates.

You will benefit from better line management on 21CN which is good! smile

Possibly a lower Target SNR (3db) if your line is stable which will increase your sync. And faster IP Profile recovery etc. if you should have a low sync smile

Remember to report back to let us know how things pan out...

How fast does WBC run compared to a standard profileless LLU service?

My line is very similar to the OP's in stats, line 1 is identical to be precise.

More or less the same but you & OP won't benefit from it.

From the line profiling and ADSL2 standard we probably would.

If doing a big download I could drop my SNR down to 0.5db and take advantage of faster speeds, unlike ADSL1 where it takes hours and hours for the profile to change.

drop down to 0.5?

if you did that you wouldn't get a connection 3db is the lowest you can go and still maintain a connection

Others have proved you can on a very stable line, altho' I personally wouldn't risk it.

In reply to a post by Seansmit17:

I could quite happily run an O2 LLU line at under 1dB during the daytime if sync'ed in the daytime, or at 1.5dB during the night if sync'ed at night.

In practice I used to tweak as low as 0.3dB and put up with two or three reconnections, as those didn't bother me and every re-sync, whenever it occurred, was faster than a 3dB margin would have given me.

Fot the poster wishing to tweak to 0.5dB, he clearly means for the period needed to download something in particular. He obviously knows what he is doing, as I did, and finds/found it useful.

You'll have seen my reply to seansmit17. There is a complication though in your case.

On an ADSL2+ line there is usually greater sensitivity to noise, so you may cause more disconnections than you are used to. The IP Profile adjustment is fine, but you would need to watch out for triggering a target noise margin rise.

I had stable 0.2dB SNR for 34 days without disconnection and my sync rate went up to 19135Kbps from 8128Kbps from ADSL1 to ADSL2+ as I tweak my netgear from 6dB to 0.2dB. Fastest 16.4 Meg at all times smile

Yeah I have heard about ADSL2+ causing re-syncs.

Thankfully the line is very quiet during the day and that is when I will be looking to tweak the SNR to gain a couple of extra megs.

On ADSL1 I can hit 7120kbps @ 0.5db SNR and it will happy run until around an hour after sunset and then the noise kicks in and I drop the SNR to 5db and it will run at 5120kbps for months.

WBC is now available on my exchange and I have placed a regrade my line.

What kind of frequencies am I looking at on my DMT graph to see if I would gain anything on ADSL2+?

I was thinking of just running it on ADSL2 unless I am planning a big download as that handles noise better according to some.
