I see that you have a modem/router with a Broadcom chipset and you are now connected to a MSAN with an Infineon chipset.  :)

Things are looking good for you but it's still early days and you should let it "settle down".

The only advice I'll give at this moment is to disconnect the modem/router from the xDSL and, thus, allow the MSAN to have some "quiet quality time" on its own. (Perhaps an hour.) Whilst the modem/router is disconnected, take that time to go through and check all of its settings. For example, does it have an xDSL mode setting? Perhaps G.Dmt, ADSL2, ADSL2+ and Auto could be the options available. You might like to try either forcing ADSL2+ or Auto, depending upon how it is currently configured.

Once you have reconnected the modem/router to the xDSL, resist the urge to "fiddle".  ;)

The connection hasn't been switched to ADSL2+ yet, I can request that when I please :).

I'll turn off the router for an hour and give it some "quality time" :).

Left the connection for an hour (turned off) and it is looking good.


Thanks for the advice burakkucat :).

I have now been moved over to ADSL2+. Unfortunately due to some instability the target SNRM has increased to 12dB, but hopefully this will reduce over time.

 . . .

Looking at the above two lines, if the first is truly representative of what your line can achieve, then I would suggest that you configure the modem to operate in ADSL2, rather than ADSL2+ mode.

But, as you say, early days. So give it some time to settle and no fiddling::)

Thank you, burakkucat. Any ideas on how to present the stats without all of the text getting misaligned?

You're welcome.

As for your subsequent query, have you tried beginning & ending the information to be displayed with either "code" or "quote" tags?

Fixed. Thank you :).

For anybody else, I used the "code" tags.

Errors seem to be nice and low too. But then again, the SNRM is quite high.

Hopefully it stays that way!

Do you know what sort of instability?  Was there any particular reason ?
That seems to be rather a rapid move up to 12dB :/

What was your SNRM when on maxdsl?

Come to think about it surely interleaving would have first been turned on, before the target SNRM was increased?  :-\

OP is probably one of those customers who insist on interleaving being off no matter what.

My experience with ADSL2+ on 21CN/WBC is that DLM is extremely eager to switch off interleaving. As I've reported elsewhere, I've twice asked my ISP to get my connection switched to interleaved, twice they've done it, and twice DLM has promptly switched it back to fastpath. This is despite the fact that my error rate is very high. (I gather from BS that there is a solution, but I haven't pursued it yet).

As far as I can tell, fast path was turned on as soon as I switched to ADSL2+.

And no, I don't.

That seems to be rather a rapid move up to 12dB :/ 

According to Zen, the line was very unstable when I moved to ADSL2+, but I can't confirm this as I was asleep and not doing any monitoring.

However, I am starting to believe that the target SNRM wasn't reset on migration to 21CN.This is because the target SNRM was 12dB on ADSL Max due to an unstable router which has now been removed and replaced with a (currently) much more stable NETGEAR DG834GT.
