I was supplied with the ECI 'r' modem for my FTTC installation and it has remained powered and connected since it was installed a few days ago.

I would like to get line stats and the Huawei HG612 seems to be easier to unlock. I am also connected to a Huawei cab. So I have a version 3B on its way to me

I am on day 4 of 10 of the initial DLM profiling. Would it be OK to swap the modems over during this period, or would it be wiser to wait? I don't want to risk being put on a worse profile but I'm really eager to start collecting stats!

Thanks

7 - 14 days would be your best bet, if you are still having re-syncs daily or every couple of days wait until you have like a 7 day free period.

In the meantime, I would suggest you regularly check your IP Profile via the Further Diagnostics button following the initial test here:-

Be mindful though that some connection resyncs can be so quick that a new PPP session isn't initiated.
A new PPP session is required to update BT's IP Profile for your connection.

A new PPP session can be initiated by disconnecting/reconnecting the ROUTER (not the white modem).

Thank you ryant and BE.

My IP profile is currently 77.44 Mbps so I will keep an eye on this daily.
My router stats appear to show no PPP reconnections but I will force a new connection every day before I check the IP profile.

[Bald_Eagle1]

Thank you ryant and BE.

My IP profile is currently 77.44 Mbps so I will keep an eye on this daily.

That's the maximum IP Profile for the full 80 Mbps service (around 96.79% of sync speed).

My router stats appear to show no PPP reconnections but I will force a new connection every day before I check the IP profile.

Doing it via the ROUTER shouldn't cause DLM to have a hissy fit

Update:
I swapped over the modem successfully on day 13 (yesterday). My IP profile has remained on 77.44 Mbps before and after the swap.

Bald_Eagle1, I'd greatly appreciate your thoughts. Stats have been collected for just over 24 hours.

That looks like a near perfect connection to me, very, very nearly achieving the full 79999 Kbps sync speed.

Your SNRM values show that you have quite a bit of capacity to spare & the almost steady SNRM & associated attainable rate graphs show only a slight disturbance at aroiund noon on 26th.

The QLN graph does show show a little overall background noise, the closer to -140 dBm, the quieter the connection.

It does show a noise spike at just below tone 3550, along with a corresponding dip in the SNR graph.
Having the spare capacity means it doesn't seeem to be anything to worry about.

Apart from a slightly wavy Hlog graph for the D3 downstream band, the snapshot data & graphs look pretty good.



Very few errors are seen over the logging period & I'd swap it for my connection any day.

[Charles]

Thank you for your analysis, BE. That's excellent news.

I think I plugged the extensions back in around noon on the 26th. Perhaps this caused the disturbance.

I imagine it can only get worse from here on as more people sign up to VDSL services and crosstalk increases. Therefore I will continue to log the stats 24/7 and keep an eye on things over the coming months.

Great work on the graphing tools, very useful (and pretty!).

Cheers,
Charles

Just a quick note:-


When using the 35m BLOB, the raw Bitloading data doesn't seem to update at all between resyncs whereas it does update dynamically when using the orginal 30b BLOB.

[DeadMan]

Currently on the 35m BLOB would it be a good idea to go back (maybe in a weeks time after things settle down again)?

[Bald_Eagle1]

Even though the new blob appeared to provide slightly higher sync speeds, I reverted to the original blob as my connection's reduced performance is being investigated (very slowly) by Plusnet & BTOR.

I didn't want either of them to find ANY 'excuses' for below par performance.

 

[pettaw]

I have found very little difference on the new blob. The sync speed is indeed about 1M higher but actual throughput is virtually identical. I can tell this because I'm lucky enough to be part of the Samknows speed trial and therefore have a white box attached to my connection.

Think of doing the same actually.
