No, my HH5A has reduced sync and interleaving on. It is also locked down but gets it's firmware updated in the same way a locked ECI modem or lHuawei HG612 does - via PTM 301 or BTAgent.

Same here I have had to move back to a Huawei modem I purchased to gain full sync... not the all in one solution I wanted though...

Maybe the roll out isn't finished?

Definitely not finished yet, a FTTC connection I manage has an uptime of 90 days (eci modem, huawei cab), ping graph showing average 23ms ping; I am keeping an eye out for an increase.

It will take a day or so for G.INP to be applied to the line mate, seen it a few times on Kitz, don't worry Leave the HG612 in place and G.INP will come.

Seems my line decided to change to G.INP at 3am yesterday. This reduced latency from about 28ms to about 18ms and increased sync from 73628/19854 to 79999/20000.

I swapped to an unlocked HG612 a few days ago, I don't know what would happen if I put the OR-supplied ECI back on and am not intending to do anything to find out right now.

As far as I can tell I am not yet on GEA-FTTC from Zen, it's still going via some BT/OR kit. Maybe once that changes the latency will reduce further, I know others are reporting <12ms latency.

Woop Woop! Finally got my old speed & pings back this morning:

Slight change of plan.

Since the HG612 was going on eBay for around £20, I couldn't resist. Snapped one up last week.

Arrived today, applied SP08 firmware (with webgui support) and looks like my latency is now back to normal.

Also, as if the line didn't sync fast enough with the ECI modem (66519 kbps), the sync this HG612 has now managed to obtain is:

Text
1 23 45 67 8	# xdslcmd info xdslcmd: ADSL driver and PHY statusStatus: Showtime Retrain Reason: 0Last initialization procedure status:   0 Max:    Upstream rate = 29083 Kbps, Downstream rate = 65340 KbpsBearer: 0, Upstream rate = 20000 Kbps, Downstream rate = 68791 Kbps Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps

Question: How can the sync speed (68791) be greater than the max downstream rate (65340) ?

The max downstream rate is calculated from the SNR margin, so I think the noise was less when the modem synced than it is now.

2) Request during the downgrade order process, and as part of ordering a brand new package/contract, that Zen ship me out their free £60 Technicolor TG589vn v3 modem/router, which according to this, does support G.INP.
...

Turns out the above only applies to new installs. So just as well I ordered the Huawei HG612 a few weeks ago, to replace my ECI.

I think Zen should make that clear on their site. It says nothing about "new installs" only; the only thing it mentions is for "new contracts" which downgrading from Fibre 2 to Fibre 1 would be.
