ADSL Max - Help Please

I have been activated on to ADSL Max from Monday - I have a 512k fixed
before hand. MY adsl stats have not moved at all from the below:

Line mode G.dmt Line state Show Time
Line up time 1:12:03:36 System up time 1:12:05:21
Downstream speed 576 Kbps Upstream speed 288 Kbps
Downstream latency Fast Upstream latency Fast
Trellis coding Enabled Loss of signal 0
Line attenuation 59.5 dB Loss of frame 0
Noise margin 21.5 dB CRC error 59
Line up count 1 Total error duration 2 seconds

The speed is still reporting 576k and 288k and has not changed in that
time I was expecting the speed to go up and down for the next 10 days
to get the most stable speed. Looking at the FAQ on ADSL Max if stated
the following

"If the line speed estimate is 1Mb or above, then we'll provide up to
8Mb Broadband. If not, then we'll continue to provide you with 512k
fixed service, this being the most appropriate product for your line."

The current estimate is 500k service but with the attenuation and SNR
as they are I can't help that something isn't quite right

Any advice please

Can I ask how you found out the figures above?
Thanks

Have you rebooted the router?

The line attentation is very high. Although the SNR looks very good.

The information was from my voyager 2000 BT even though I have a BT hub
- I agreed the SNR looks good and the attentuation is on the edge but
if I go onto ADSL Max what should the downstream speed be reading?
should be a different figure every x amount of minutes as the line
tries to get the most stable speed?

If you have rebooted the yoyager several times throughout the day and it
is still exactly the same stats it's unlikely you are on rate addaptive DSL.

what about the readings?

For example the upstream changes from 244 to 444? or the interleaving
is set at default? what other indications are there to ascertain
whether I am on rate adaptive DSL

Cheers

On ADSL Max you modem will sync at the speed which achieves an SNR margin
given to it by the exchange. The initial margin is 6db.

The modem will stay at that speed until you manually re-sync or it gets a
too high CRC error rate which will cause it to automatically re-sync.
If the line is noisier than it was when it last synced it will probably
sync at a lower speed to archive the same SNR margin.

If you modem has to re-sync frequently (10 times per hour is a figure I
have seen mentioned but I don't know it is true) the exchange will consider
your line to be unstable and increase the required SNR margin passed to
your modem by 3db. These increases will continue until your modem stops
frequently re-syncing.

Looks to me like you don't have an ADSL Max connection yet, that or the
exchange has already gone through several SNR margin increases.

You do have a long line, if it needs 21db of SNR margin it must be a very
unstable long line.

The SNR, downstream and upstream changing are the ones to look for.

I always believe that a higher snr was good but it the figures stay the
same so in 24 hours would you say that I am still on a fixed packages?

The faster you connect the more 'signals' you need on the line at the same
time. The signals have to be smaller to fit so the ratio of signal to noise
goes down.

ADSL Max goes as fast as it can while retaining a defined minimum SNR
margin. Most lines work with the default 6bd margin, lines where the noise
varies need more margin to cope with the noisy times.

At a given connection speed varying SNR is an indication of varying noise
on your line not the kind of ADSL service you have.

Your connection speed will not change without the modem re-syncing and the
modem will not re-sync automatically without a high CRC error rate
triggering it.

Reset your modem to force a re-sync and see if the speed changes, if not I
would contact your ISP now. It doesn't look like you are on an ADSL Max
service.
