wratterus:I just flashed it with 3.8.2 m8 to check - same thing. So there is no nice green 'vectoring active' note on the dashboard for the DV130.

 

 

Dang, the DV2860 rich kids do, thats no fair :(

 

 

If you can wait a couple of weeks I hope to be able to report back on the Mikrotik + V5311 SFP in regards to vectoring. Just waiting on @Chorusnz to flick the switch at our local ISAM.

 

But it does not report line stats either.

My cabinet, AON_G switched at 2am Tuesday.  I'm near the vdsl limit for the cabinet (24.9 atten DL).  The resynch remained within the normal range for my DL and UL speeds (27/3).  Noticeable changes are a drop of 4 dBmV in downstream output power (now 14.4) and a change in ping from 20ms to 9ms to Spark Auckland.

Power drop sounds like 8b to 17a. So keeping the same speed would be a positive there.


For most users on longer lines, gains in speed will be low but latency will be improved along with line stability.

timmay556: Hey guys, I see that my exhange is booked in for today ( I even saw a chorus van parked outside the box on my way to work this morning) is the change over immediate or does the effect take a few days?

 

if you mean today, as in on the list i published...

 

 

 

No physical chorus man will be there, they do it remotely. It's done in the weee hours of the morning.

 

 

Yeah using that map you posted. I'm on TPO\BP.

 

Does it make much difference for us plebs on ADSL?

ADSL is not vectored.

Vectoring downstream rate graph

 

 

 

Remember to pay attention to this graph as it's real data. lines sub about 45mbit all cluster about around where they were prior to vectoring.

 

This means you won't really see very much gains that aren't within margin of errors.

 

 

 

What you should gain from this is stability, reduced latency and reduced error rates. The later should result in ddDLM pushing your profile slightly faster aswell..

 

take my line for example, i realistically expect it to raise to maybe 25mbit.

 

 

The gains for me, will be switching my second line over as the next end crosstalk is the biggest hit.

i'd totally be a fan of option 1, i'd compromise on 2 ;)

Not sure where this image came from, but please be aware that Chorus doesn't use 3 or 4.
When we talk about "Legacy CPE", we are always referring to option 5.

 

1 is ideal, 2 is used if that's all a modem supports.

Switch over has happened, a little disappointing after such a long wait
But a small gain all the same on Downstream sync, upstream pretty well identical to what it was
Good to no longer have any Interleaving going on giving me a 3ms boost in pings
Probably shows my line was clean to start with and nothing to clean up

 

I'll trial the nf4v modem on the weekend to see how Broadcom chipset does

DV130 Telnet command with a little more info is 'vdsl optn status' which reveals this:

 

Vigor> vdsl optn status
trellis [US] = ON, [DS] = ON.
bitswap [US] = 0, [DS] = 0. [0: default(ON), 1: ON, 2: OFF]
sra [US] = 0, [DS] = 0. [0: default(=3), 2: OFF, 3: ON , 4: DYNAMIC_SOS]
retx [US] = ON, [DS] = ON.
aelem ON
G.Vector ON

my apologies, i was counting from the non positive options...

 

 

Ofcourse it's not what you guys do and there area pretty valid arguments against it, i'd have liked it though :3

 

 

 

on to me and my vectoring experience..

 

Unfortunately, vectoring didn't successfully go live on my dslam - oh well, it happens. i shal await the cleanup

 

 

 

Good news, i have  G.INP now atleast!

 

Unfortunately, the new profile seems to have a lower US0 PSD mark, this nets me a drop in upstream speed, also a bit of a dip in downstream.

 

 

 

 

as for my ADSL line, this looks to have had it's earth contact returned unfortunately... So it's not really fair to comment on that, no massive changes though outside of what's expected for that fault.

Some interesting vectoring observations at my end this morning,

 

CydG went live this morning around 3am, Scheduled for 23:00 4 hrs earlier.

 

 

 

I have 2 vdsl connections 1 with snapdegrees and the other with spark. 550m from a cabinet on 1980's copper. 

 

Connection 1

 

Snap degrees b10a zyxel modem

 

previous sync 64 down 13 up, would speed test at 59-11

 

checked dsl stats this morning saw the resync to 80-13

 

Speedtest would only produce pre vectoring speeds, rebooted modem 79-13

 

 

 

Connection 2

 

Dv130 on original firmware 3.7.5 on spark

 

previous connection 58-11 after vectoring the same

 

updated to modem 8 vectoring firmware. 

 

and 69-11 on speedtest 

 

 

 

It was interesting to see I had to reboot even after the resync on the zyxel to get the new profile

The permit window starts at 11pm. I have 230 DSLAMs to do between 11pm and 6am :)

 

Its unlikely a reboot actually changed anything, as enabling vectoring causes a resync anyway - probably a placebo for speedtest.net typical inaccuracies.

also possible PPP Session held over the resyncs and the speed limit was on the RSP side :)

would have to be quite a fast resync? LCP timers are usually seconds, not minutes.
Possible though I guess.
