hi i am from Pakistan and here my isp ptcl has launched vdsl2. I read about INP and interleaver depth on this website and i want to know what you think of my stats and any tips to increase quality of line. And please help me understand what the values like INP (DMT symbol) and interleaver depth tell about config of  dslam

i am sharing here 2 stats screenshot one recent one with 16ms delay and other one old when fast path was active with 2ms delay

and my pkg is 15mb download with 8mb upload speed and extra speed is for iptv

Welcome to the kitz forum.

I'll just say that, after a quick look, your circuit is operating quite well. I'm sure that one of our knowledgable members will be able to give you some guidance of the various parameters appear in the statistics.

Your line is capable of about 65/40.
Syncing around 20/8

High Interleaving with 16ms delay added to the downstream.

No G.INP which is a shame.

[neil]

thanks for reply yes it is 20mb with iptv it was synced at 17000kbps without iptv
vdsl2 was installed in jan 2019 and before that i was using 2mb adsl2 which was very bad with frequent disconnects

Welcome to the Forum Neil:

> Can you please share how you can tell G.INP is not enabled

More the absence of things? Can’t see any mention of G.INP-related stats, that’s what I think. But then I don’t know what I’m talking about as I don’t have VDSL2.

> is it last one in stats INP(DMT symbol)

I think not. That’s something confusingly similarly named if I’m not mistaken, which I very well might be.

Bearer 1 not in use.

Bearer 1 not in use.

path 0 and path 1? they are called bearer? my telephone wire is single twisted pair coming from pole? that's why only path0 showing stats and path 1 is empty?

No, that's not the case.

I can see how it can appear to be confusing but Bearer 0 (or Path 0) and Bearer 1 (or Path 1) do not relate to the physical cable (the infrastructure) but are entities within the VDSL2 (ITU-T G.993.2) service.

If G.Inp (ITU-T G.994) is active on the line then there will be some data present under the Bearer 1 (or Path 1) heading in the statistics.

Would just like to point out that the OP is in Pakistan - we'd have no idea if they even have G.INP on their equipment?

Maybe they use ECI? I'm afraid I am not an expert in the nuances of FTTC in other countries..

when MSAG was installed i was there and it is ZTE MSAG here is the picture

[dee.jay]

Yeah we don't use ZTE here in the UK, kit is either ECI or Huawei...

Excellent you've been able to provide the name of it though. No doubt some of us will be googling to find the capabilities

[neil]
