Line Stats Comparison


[link to this post]
 
First post on here so please be nice with me...

I'm on PlusNet and happy with the service but like most people hope for a little more speed on my 80/20 service.
Below are two snipets of stats. First from my ASUS DSL-AC68U working as an all in one solution and the second from an unlocked HG612 using the ASUS as a router only;

ASUS;

SNRMarginDown=6.1 dB
AttenDown=10.4 dB
SNRMarginUp=6.1 dB
AttenUp=0.1 dB
DataRateDown=60392 kbps
PathModeDown=FastPath
DataRateUp=16456 kbps
PathModeUp=FastPath
FECDown=716
FECUp=72
CRCDown=84
CRCUp=15
HECDown=0
HECUp=0
ADSLUpTime= 3:39, 53 secs
AttainUp=16527
AttainDown=75088

HG612;

Max: Upstream rate = 17046 Kbps, Downstream rate = 57924 Kbps
Bearer: 0, Upstream rate = 16983 Kbps, Downstream rate = 58396 Kbps
Down Up
SNR (dB): 6.1 6.0
Attn(dB): 17.3 0.0
Pwr(dBm): 13.2 6.9
Total time = 1 days 12 hours 21 min 19 sec
FEC: 0 1787
CRC: 1549 290
ES: 1217 279
SES: 0 0

Now the bit that gives me hope of more speed is the AttainDown=75088 on the ASUS. Why would this be so different to the 57924 figure on the HG612? I realise the actuals are similar(ish) 60392 vs 57924 but if the ASUS is to be believed surely I should be able to sync at a higher speed?

Just for info I'm on an ECI cab (also have an ECI/r modem) and have just installed a MK3 faceplate to replace the old MK1.

I appreciate your thoughts?

TIA, Mick

It is not known how the different VDSL2 modems handle the power masks, i.e. three different ways that VDSL2 is configured for the Openreach network and this means in some cases the estimates of maximum potential speed may be over stated.

Power masks exist to protect the performance of ADSL2+ so if ADSL/ADSL2+ was turned off one day higher speeds from VDSL2 are possible.

Thanks. From what I've read the HG612 info is considered to be quite accurate so it's likely then that the ASUS is overstating the MAX figure?

Also I believe that the ECI/r modem that I have will connect slightly faster (on an ECI cab) than the HG612? But I won't get any stats and I don't want to mess with it..!

Can you install DSLStats and then take a couple of snapshot images of the Tones graph with SNR overlay and of the QLN graph It would be interesting to compare the two versions to see where the differences actually are.

I've got DSLStats running now but thought it would only work with HG612 not the ASUS.?

Also (a potentially dumb question) how do I insert the graphs into a post?

You cannot upload to a post - just host them on a suitable site - photobucket, flikr &c and post the links.

OK. Is this what you mean? These are from the HG612.

Not sure I can get them from the ASUS though..!!

Almost ... under the Tones tab there are two further tabs, the Bit loading would be useful too.

If you can get the ASUS ones, a comparison may shed light on the differences.

Okie Dokie.

Here is the other https://flic.kr/p/zuRDDj

I'll have a try later and see if I can get anything out of the ASUS.

Nothing obvious there!

Also worth a small tweak to settings:

Select the <Config> tab, then <Items to Monitor>, Under Others, select <SNR per tone>, <Show as separate graph> and <Include with bitloading> That will overlay Bitloading with SNR.
