Hello Guys and Gals I was under the impression that when you switch provider like i,ve done you get a line reset or re-calabration or something like that but nothing has changed still on G.INP didnt go to interleaved

Left the Zyxel 8924 inplace overnight during switch over which looks like it occured at 3am to Vodafone did checked the stats this morning as the Internet led showed red on Zyxel but still had DSL info as expected, Put the THG3000 Modem/Router online and yeah no change to VDSL stats

Do you find this odd ?

Ps I did ger DSL username and password this afternoon to use on any Modem/Router this time

G.INP now remains after a DLM reset or an ISP switch (on Huawei cabinets).
This was 1st spotted on Bangers connection some time in the last year or 2, I can't remember exactly when.

I've no idea if G.INP is on immediately on a new provide or if there's still a few days wait.

Thanks John for this information have been out of the loop for a while now but didnt expect to see this so things have all changed don't know if it's for the good or bad as seems im stuck at 38Mbps instead of the new rate of 43Mbps

[burakkucat]

. . . seems im stuck at 38Mbps instead of the new rate of 43Mbps

Ignoring the ISP/CP's advertisements, upon which underlying Openreach product is your service provisioned? 80/20 Mbps, 55/10 Mbps or 40/10 Mbps?

Next, what information is returned by a xdslctl info --show command?

As an example, here follows what I see for my own circuit --

In particular, look at the "Max:", "Bearer: 0," and "SNR (dB):" lines. From those lines you should be able to deduce that my service is using the Openreach 40/10 Mbps product and, although my ISP/CP tries to induce me to move to the Openreach 80/20 Mbps product (at a greater cost), there is not sufficient "headroom" for me to benefit from that change.

Look at those three lines, reported by your ZyXEL VMG8924-B10A, for your own circuit. Do they hint of any "headroom"? If the answer is "no", then that "new rate" of 43 Mbps is just vapourware.

[NewtronStar]

At the moment BC I can see the SNRM on G.INP went down from 4.3 to 3.2 so the actual downstream increased from 39999 to 43768 but in real life doing some BT speed tests all I can get is 37998

G.INP now remains after a DLM reset or an ISP switch (on Huawei cabinets).
This was 1st spotted on Bangers connection some time in the last year or 2, I can't remember exactly when.

I've no idea if G.INP is on immediately on a new provide or if there's still a few days wait.

My experience with a migration from Plusnet to Zen last December on 40/10 Huawei DSLAM service.
Yes, DS G.Inp with low re-tx profile was retained at switch over.
However, changed to high re-tx profile during the subsequent DLM migration steps from  6 to 3dB DS SNRM, modem speed clamping had to be utilised to re-establish low re-tx profile @ 3dB DS SNRM.

Full process was recorded here:
https://forum.kitz.co.uk/index.php/topic,25387.msg427229.html#msg427229

[NewtronStar]

Cheers tiffy for sharing your experience during migration

Can understand why they would now leave G.INP inplace during line reset or migration as customers may have complained about there loss of sync speed due to the higher 6db DS SNRM and loads of CRC/ES when in the interleaved period especially on noisy lines so a good move I think.

[NewtronStar]

I am wondering does Vodafone do a 50/10 service definitely EE was on the 40/10 connection speed would never show anything above 39999 kbps, here are two DSLstats screen shots before and after

[burakkucat]

I am wondering does Vodafone do a 50/10 service . . .

The Openreach VDSL2 service products are (were) --

0.5/0.5 Mbps
(18/2 Mbps)
(40/2 Mbps)
40/10 Mbps
55/10 Mbps
80/20 Mbps

If I am remembering correctly, the second and third are no longer available.

So it does look as if your service is provisioned on the 55/10 Mbps product.

[NewtronStar]

That is the same conclusion I,ve come to burakkucat 55/10 yet my line seems to still think its on 40/10
service via thoughtput/speedtest results 37898 Kbps

[burakkucat]

If the migration was only a couple of days ago then perhaps allow some time for the service to "stabilise"? (Whatever that word may mean.)

One other thing that might be worth trying is to power-off the modem/router over night . . . just the once.

[NewtronStar]

BC I think this line became banded 7 months ago when the DLM introduced that RTX High level it had stayed a Low level for 11 months but obviously something must have triggered it to high.

So was thinking of lowering the connection speed to say 28000 Kbps for upto 2 weeks and see if that has any affect on the line.

Have forgotten the command wording and numbers used in DSLstats to implement it  it was written down on paper but lost it.

[j0hn]

Cap the line at 35Mb. That should nudge the DLM to put the line back on Retx Low.

[NewtronStar]

Good old google takes me to a page on the Kitz site adsl configure --maxDataRate 60000 15000 100000, so setting it to say 35000 6200 100000 should do it John ?

[meritez]

That should do it.
