The line shouldn't be far off 80Mb in 2 days after interleaving is removed and G.INP applied.

Thanks both. All happens automatically I take it ? Will just leave everything connected as is?

Yes all happens automatically, but not always in two days, sometimes it's longer. Once G.INP is applied the target dB will be reduced if the line is considered stable enough, you should easily get 80Mbps.

Hey All.

Decided to migrate over to the HG612 this morning. The rx sync speed actually went down from 68 to 62Mb between the sky hub and the hg612 respectively, but I have not dared attempted a reboot. I kept the modem off for about 40 minutes after disconnecting the sky hub. However this means that I have now been able to take full line stats which I show below.

The HG612ís IP is set to 192.168.10.1 (changed from the default of 1.1 which is the same as my router) - despite setting up a static route on my router to pass traffic for 192.168.10.0/24 to 192.168.10.1, I canít access it from my main network. Always need to plug in to LAN2 with a laptop and manually set an IP on it within the 10. range. Also tried following steps I saw on AAISP wiki to allow me to access the modem via the LAN1 port, but I canít set the WAN port on my router to a static IP because quite rightly the modem passes the WAN IP it gets from Sky to this interface using DHCP.

1. I donít think G.INP has been applied yet

2. Do my stats look good or would any of you express a cause for concern ? Iíll need to learn to interpret these graphs I am afraid

The plots are quite respectable. I cannot see anything that would give me cause for concern about the state of the metallic pathway between the modem and the DSLAM. There is a little sign of some cross-talk with other circuits but there is nothing to worry about . . . especially as nothing can be done about it.

I can confirm that currently G.Inp (ITU-T G.998.4) is not active on your circuit.

Why don't you set the modern to 192.168.1.254 and just connect LAN 2 to spare port on the router or to a switch if you have one?

I'l try that - thank you.  Just ran out of time yesterday.  Apart from that, does everything else look OK? Roll on G.INP - I did phone sky about when it's likely to be applied but they did not understand.

Most ISP's don't understand the FTTC DLM.
They have absolutely zero control over it.

Thanks John. Ok, Iíll just sit tight and be patient and hopefully over the next few weeks Iíll notice G.INP be applied.

I'm no good at interpreting the stats, but g.inp can take a long time to be applied,  my brothers took absolutely ages, no idea why.

Yes. As I said in reply #95, above.

Cabinet 25 DSLAM Installation
« Reply #102 on: May 23, 2019, 12:24:05 AM »

Hey All.

Not sure how well you can read the below. Iíll now have had the service installed for almost exactly 2 weeks. At exactly 11am this morning, my DS and US attainable rate dropped quite considerably - 75000 to 64228 (I am synced at 64294) and 25000 to 23183.

SNR margin dropped from 6.9 to 3.6 DS and 15.3 to 12.4 for the US.
 
G.INP still not enabled.

Got a bit of a shock when I saw the attainable rate drop off by more than 10mb, as I was hoping to creep up to that speed. Is this just DLM doing its thing or did something have an impact at 11 this morning ? (machinery or new VDSL connections being added?)

Sorry. I can't make out anything from that montage.  :no:

Sorry, that was the ďfullĒ graphic produced for the last 24 hour period showing the drop in attainable but didnít realise it was such low res. Here is a before and after current line stats from 2200 on 21st and 2200 on 22nd respectively. Thank you in advance for all your advice :)
