HH5 Type A to an ECI cab, apart from the 14 day reboots with the HH5 the connection has been rock solid since 2011 through a HH3, HH4 and HH5 Type A.

However Openreach recently carried out work on my cab i noticed my max attainable has altered and problems have started.

My upstream has dropped to 26000 from over 33000
My downstream has increased from 102000 to 108000 but my actual sync dropped to 78000 from 80000

That in its self isnt a problem i guess but now my HH5 is rebooting 4 or 5 times a day which clearly is a problem.

I have done a quiet line test and the line is quiet.

Any ideas?

Hi MrBelter,

Please can you post your line stats: http://192.168.1.254 - Troubleshooting - Helpdesk.

This could well be due to a customer being connected to your cabinet who is very close to you and could be a major "crosstalker".

Its all altered slightly since i posted but as you can see it still not the 33000/102000 it was

4. Board version:   BT Hub 5A
5. DSL uptime:   0 days, 03:10:26
6. Data rate:   19999 / 78639
7. Maximum data rate:   26668 / 107997
8. Noise margin:   9.6 / 13.5
9. Line attenuation:   4.4 / 5.7
10. Signal attenuation:   4.3 / 5.7

Ive noticed over the last 2 days the TR069 log has gone mental as well.

[MrBelter]

This could well be due to a customer being connected to your cabinet who is very close to you and could be a major "crosstalker".

Im assuming the cab is full, when i first got FTTC my max attainable was 130000'ish and over the years it has dropped to 102000'ish but all of a sudden it has jumped up to 108000'ish

[MrBelter]

Just had a look and there arent any new SSIDs around, same old same old on that score.

[William Grimsley]

Hmm, interesting. It could be something to do with G.INP being implemented...

[MrBelter]

I hope not, its never missed a beat up to them pratting about 

[MrBelter]

Some stability seems to have come back, its been up over 2 days now but the stats are the same so i am guessing the HH5 was finding its feet after being G.INPed.

Oddly BT offered to send me another Home Hub within about 3 minutes of a live chat and it is normally blood out of a stone with them isn't it. Anyway unless it is a HH5 Type B to try and see what the stats looks like i might as well just send it straight back because i am pretty sure it isn't the hubs fault.

Half wish i had not sold my Huawei modem now 

[MrBelter]

Its all altered slightly since i posted but as you can see it still not the 33000/102000 it was

4. Board version:   BT Hub 5A
5. DSL uptime:   0 days, 03:10:26
6. Data rate:   19999 / 78639
7. Maximum data rate:   26668 / 107997
8. Noise margin:   9.6 / 13.5
9. Line attenuation:   4.4 / 5.7
10. Signal attenuation:   4.3 / 5.7

The replacement HH5 Type A arrived and unsurprisingly there is very little difference (a couple of Mbit on the upload)

6. Data rate:   20000 / 78639

[Dray]

Yes a Huawei modem or a HH5B may get G.INP on your ECI cab.
A HH5A won't

[S.Stephenson]

Yes a Huawei modem or a HH5B may get G.INP on your ECI cab.
A HH5A won't

A HH5A does support G.INP doesn't it, it was fixed in a firmware update.

Or did it break again?

[Dray]

No I haven't seen any evidence of the HH5A supporting G.INP on any firmware. The HH5B does though.

[S.Stephenson]

No I haven't seen any evidence of the HH5A supporting G.INP on any firmware. The HH5B does though.

I was under the impression that the HH5a on a Huawei cabinet would work with G.INP on the downstream only, the problem that BT had initially was enabling G.INP on Up and Down by default and the ECI modem and HH5a couldn't handle it, so they just disabled it on the up as a cheap fix.

[Dray]

A lot of people say that, no evidence though. However, plenty of evidence that the HH5A does not support G.INP and the HH5B does.

[burakkucat]

I would just like to make a brief comment and a polite request . . .

Brief comment: There has been a long-running disagreement between various persons in the TBB forum on the subject of the BT HH5A, BT HH5B and G.Inp support.

Polite request: Please don't bring that disagreement here.
