Topic # 127537 13-Aug-2013 23:20

Hi all!

I have taken a look at the VDSL thread and I'm just after some extra info if anybody can help me out, especially since the thread is Fritz!Box orientated.

I can't tell which DLM profile our connection is on, if anybody could tell me that would be great, I've attached a screenshot of the xDSL Statistics page from the Innbox.

Also how do these figures look for Attenuation and Output power? Is there any problems with the connection?

Thanks! Any help would be much appreciated!

Regards
Stefan Andres Charsley

mind doing a tracert to say, trademe, it would seem your modem may be miss reporting the latency delay values.

Heres the tracert, I did it twice just in case of any anomalies.

seeing that 283, over wireless by any chance? :/

35ms to first hop doesnt sound too pretty, indeed looks like a 16ms each way profile, was about to try calling it a DLM-2, but thats DLM-5 by the looks of it.

do you have a filter installed?

Yes over wireless but I'm right next to the AP, that first one was probably the wifi driver on my laptop waking up.
And yes we have a master splitter installed straight on to the Chorus cable as we have no External Termination Point, the modem is plugged into that and the POTS line connects back into the legacy POTS wiring in the house.

in terms of wireless, be aware of over-saturation ;) but yes, that makes sense.

line should be pretty clean on your internal network then.. whats the uptime on the connection, hard to draw CRCPM without it. but i dont see any obvious signs as to why you should be that high in profiles..

how long has your connection been previsioned for? outside of training period? if so, ild suggest you have fullfavour? get a full line report.

hard to draw your attenuation from the stats with the whole split in the bands, and the derp in the firmware, i think i read someone else say that is fixed in the new firmware however. but it looks like you could be close to your limit in terms of distance, but you still should be able to get to a lower profile..

Uptime of 2 days. The firmware is very derp. I've had to reboot the Innbox a few times. We've had the service for around 3 weeks I think. And yes it's Full Flavour.

One person supports this post

charsleysa: Uptime of 2 days. The firmware is very derp. I've had to reboot the Innbox a few times. We've had the service for around 3 weeks I think. And yes it's Full Flavour.

so thats just over 1.0CRCPM, surprised its that high on that profile..

have fullflavour do a full line report, might show up that its a certain issue causing it.. we have seen things such a lamp post short wrecking havoc on lines, my bet is that that error rate isnt consistent on your line.

3 weeks should be well outside of the trainning period, so you have given the connection a fair amount of time to settle..

To be honest all this focus on which dlm profile you are on is relatively useless since as a end customer you have no control over your profile as it's set automatically. It's really a case of if your broadband isn't ok or what you expected then get your isp to run a line test and make sure they inspect the results.

yes, dlm profiles are pretty much unchangeable to a point, personally my profile sits at DLM-2, i just accept thats the best its gonna get till i can get my issues sorted. by charsleysa asking the question, i make the assumption they are looking for a lower profile.. as would i be if i had a 16ms profile...
