New max rate?

Well I recently looked at my line stats and basically my snr is always 11, sync is always 7616, max rate is always around 8128 but it's interleaved.
What I'm wondering is since yesterday my snr has increased to 15 and usually when it does my sync drops to around 7000, this time it has stayed at 7616 but my max rate is now around 9000.
Not knocking it but has my line randomly improved? my attenuation is 27.7 and hasn't increased so I don't think Ive been moved to 21cn, anyway heres my line stats in a better prospective

Rate: 7616 kbs 832 kbs
Max Rate: 9480 kbs 1088 kbs
Noise Margin: 15.0 dB 14.0 dB
Attenuation: 27.7 dB 18.0 dB

Yes, you have been moved to the WBC/WBMC (21CN) equipment in your exchange, but with an "up to 8Mbps" (G.DMT) profile on it. Don't confuse that with IP Profile.

Most ISPs do that initially, then at some stage upgrade the customer to full ADSL2+. If you contact them you might get it done almost immediately. A very few ISPs do charge more for it though.

You would be looking at a connection speed of 17Mbps or so on ADSL2+. Over 1Mbps upload unless yours is one of those that slug it.

Even though the RFS date is 30.08.12?

Umm. Odd. Maybe I'm wrong. Which ISP is it? With some you can tell from your control panel if you know what you are looking for. They should be able to tell you anyway .

The attenuation doesn't mean much in such cases, as the G.DMT profile would keep it as before.

It's BT, I was planning on ringing them but figured I'd get "We cant give out this information" so I didnt bother.

Just restarted my router to see if it would do anything, my snr went back down to 11 and my max rate is back at 8252 kbs :/

You'll probably find if you do a restart well inside daylight hours the max rate and noise margin will both increase again. That's normal because the base noise level is lower then.

Sorry about misunderstanding the stats before.

Im surprised ISP's would automatically put customers on adsl2+, as you need a compatible router for that. People who arent tech savy could have problems then

What happens if you're on adsl2+ without an adsl2+ compatible router?

Then I guess your ISP identifies this when you ring in, and advises you. There was an old router in our exchange, non ADSL2+ compatible, it worked fine but would only negotiate 8128 sync, when we eventually swapped it the new one synced at 24 meg !

A little later on in the thread, it looks like just a glitch, with 832 upstream I'd reckon the OP was still on a Max Premium service.

Isn't Max rate a Theortetical Attainable rate on ADSL(1).? When I was on ADSL(1) I used to get a Max rate of around 10000kbps but sync was always 8128 fast path.

Maybe you'd better ring them all then and check. I'm 99.9% sure I am right wrt the majority of ISPs and will continue to post as earlier until proven wrong .

As Zarjaz says, the user with an non-ADSL2+ router wouldn't see a problem. The MSAN would just negotiate down.
