G.INP

I recently moved house and back on a VDSL line.

I'm connected at 79mbs (just under full sync) with a margin of 6.2db

Been connected since the 10th and just wondering when G.INP will show it's self as I my previous time on VDSL with it showed great benefits

My current provider is sky if anyone is interested.

It certainly will if you're on a Huawei cabinet with a Broadcom based modem. Other combinations, I'm not sure.

Yes the Cab is 100% BC based and not sure what chipset the SkyQ hub uses.

Possibly 2 days to a month or you may not even see it if you have low Errored Seconds. The Algorithm usually applies Interleaving for a while then G.INP on a new line.

Been in sync since the 10th bar a power cut and some new firmware applied to the router from sky.

anyone know what chipset the skyq hub uses?

Once G.INP is applied I would sync at full 79999? as I remember last time it put about 8mb on my attainable rate on my old line.

If the Hub has a BDCM chipset, and if DLM decides to enable downstream G.INP, then yes you would.

This is the DSL firmware version

A2pv6F039m1.d24m

if anyone can tell if its a BC from that

Is it the Sky Q Hub? I'm pretty sure that uses a BDCM chipset.

Yes its the sky Q hub it does state it supports G.inp

Good! Hope it comes soon! Try not to keep waiting as it'll make the wait longer!

It does indeed use a Broadcom chipset.

Thanks for confirmation. It would be silly for router manufacturers to still be using Lantiq or similar chipsets.

We had a new line installed recently along with a new infinity service on a relatives connection . Took 12 days from going live for g.inp to be enabled. The line had minimal errors pre g.inp

Did you go from downstream FEC + INP 3 to FEC + G.INP?

The line activated in fast path with no interleaving or delay then went straight to g.inp. See btmaxcd on mydsl for more info . stats have been uploaded since point of activation. Note - its reported as eci but its not as the huawei cab can be seen out the window

Oh my, it's skyECI! How are you? That's lucky re the minimal errors on fastpath! I remember that there were thousands of downstream CRC's/hour when there was downstream fastpath on my line... I would take downstream fastpath over G.INP any day, as I get 20 - 25 ms pings with downstream G.INP... Shame it can't be that way.

As I said.. sadly not my line. Its a relatives line.. wish it was mine. 55/10 with 89mb attainable lol.. if only....

Ah, whoops! My bad! Is there any possibility that you may be connected to a Huawei cabinet any time soon?

I think my is a stable line as the margin has not moved and still on fast path for the last 7 days.

I did plug in my Zyxel router to see stats and left it on for a few hours and seen 0 errors in every counter.

For ny eci line sadly highly unlikely... the eci cab was full for a while and not taking orders and now it is so I think perhaps another card was added.

That sucks, well good luck.

There is broad agreement that Broadcom chipsets with reasonably recent firmware blobs perform well against both makes of DSLAM found in the Openreach network and are a particularly good match for the Broadcom based Huawei DSLAMs. However, that does not mean that other vendor's chipsets are incapable of performing well on the Openreach network (some highly regarded devices, such as Draytek's Vigor 130 modem bridge, do not use Broadcom), or that the apparent superiority of Broadcom based CPE translates to other VDSL2 networks.

The router manufacturers serve a far broader market than the UK.

Well I think it's been enabled as I have had a resync (or couple) at about 5:30 this morning and now my stats are..

Connection Speed 79999 kbps 19999 kbps
Line Attenuation 14.5 dB 0.0 dB
Noise Margin 6.8 dB 15.15 dB

The latency has not increased at all either if anything it's 1ms lower.

Took 9 days from going live to G.INP (if enabled)

I would say yes if the line was in a fastpath state, but we can't confirm this without a modem using a BDCM chipset with detailed line stats.

Edited by deleted (Fri 19-May-17 09:36:49)

IIRC from mine, if that's the ZyXel modem/router then the full stats using telnet in a command line window will make the activation or not of G.INP clear.

Again from memory, xdslctl info --stats

Or connect the ZyXel some time for an hour or so.
