My HH5 Type A no longer reboots every 14 days, it now seems to be every 5 days, it's a pain in the �rse

Are you on an ECI cabinet?

yeah unfortunately

There seems to be a problem with how they implemented G.INP on ECI cabinets with vendor type IFTN 0xb204 which causes upstream instability. Could be that.

I cant even be sure if they have implemented G.INP on my cab cos i flogged my modem some years ago but this new shorter reboot cycle has been regular as clockwork since my max attainable upstream dropped and my max attainable downstream went up.

I think the best solution is to bin the HH5 off, a bit of a shame as i have always been a fan of it, its been really good on my line.

In reference to www.kitz.co.uk/adsl/IPprofile.htm:

VDSL / FTTC
Calculated as 96.79% of the sync speed or 96.69% for g.inp lines.
To get your sync speed from your IPprofile: Sync = IPprofile / .9679

In reference to windows.mouselike.org/be/index.asp?DoAction=BrasChecker:

The current Downstream BRAS rate is: 73.63 Mbps
The current Upstream BRAS rate is: 20 Mbps

I was given a HH5 Type B yesterday so that's me happy.

Oddly even though i am on an ECI cab the Type B has synced at the same speed as the Tybe A, my old HG612 always used to sync 4 or 5Mbit slower.

Fingers crossed for no more 14 days reboots and although this might be in my head the WiFi is better, not the range that's about the same but stuff is loading snappier

So I got a HH5a a couple of weeks back and today thought I would do a test as my upstream g.inp don't seem to be coming back anytime soon....

As you can see the syncs are the same.

Now the normal thing to see with tradional interleaving was the actual sync of the line dropping and the maximum attainable rising by 4-5mbps

Openreach Broadband Boost engineer's who tested my line recently told me that my lines speed of a Fastpath profile was high-end of 63000kbps, and then when G.INP was enabled on my line I gained an additional 6000kbps (which was pretty much identical to my increase at my last address)


So if the HH5a was not capable of G.INP I would expect to see either Increased pings and a gap between the 'data rate' and 'maximum data rate' figures or the loss of around 6000kbps to my downstream speed.

So I deem the Home Hub 5A G.INP capable as to the requirements of SIN498

A better indicator is to compare the ratio of the sync speed and the IP Profile.

We've already been told that the ratio is different on different chipsets
