FTTC - BT IP Profile Set Low

Hi everyone,

I've noticed that the BT IP profile for FTTC connections is being set too low. Does anyone have any ideas on what could be causing the problem and is there a possibility of someone investigating this? I wish I could but I've no idea where to start.

Thanks,

William

What percentage of your sync rate is the IP profile set at?

Is G.INP active?

Are you on the variable SNR trial?

Sorry, I forgot to tell you those things.

94.42%.

Yes.

Yes.

And how stable is your connection? Does the sync rate change over time? If so it could be the sync rate has increased but that the profile is lagging behind a little.

Very stable, but not as stable as previously due to being the trial, the only resyncs have been due to DLM changing the downstream SNR margin.

So what has the lowest sync rate in the last week to 2 weeks been? How does that compare with the IP profile?

In the last 2 weeks, the lowest downstream rate has been 36400 kbps. However, in the last week, the lowest downstream rate has been 43742 kbps.

Somebody posted a while ago with a low IP Profile, and I replied I have had this happening through several re-sync's.

I have the advantage that my ISP control panel gives the system log for my connection, as opposed to purely my line as shown in the router log.

BT Wholesale are reporting to AAISP a figure a consistent percentage below the sync. The IP Profile was 0.9669 x that BT Wholesale figure.

Here and now I can't find the relevant log It may be the Radius log, and I haven't re-sync'ed for several weeks and it only gives a few days.

Perhaps poster needs to move to an ISP such as AAISP to get more access to more data on the line, so they can manage the line

I'm on AAISP and have the same problem. But complicated by the fact my line has been banded for months. I'm wondering if there is a connection between banding and false reporting. By either BT Wholesale or even the Openreach info passed to the user modems and displayed by them. (This has been happening on five different ones).

The sync shown is the capped figure as per the line profile that AAISP have. At the moment, as just posted to the OP, I can't find the log that gives the long bps supplied by BTW. (bps, not Kbps or Mbps). That's the figure the IP Profile is based on.
