Exactly the same problem here, ECI modem on a Huawei cabinet - was syncing at or very close to 80000 but now I'm on 67920 with double the ping.

Emailed Zen and they don't know if G.INP has been enabled on my cabinet and fobbed me off by saying just do a modem reset!

Watching this thread with interest...

Has the latency increased by more than the standard 7-8ms ? if it has then it is most likely the case you have been G.imp'ed

For instant results you would use the HG612. If you want an up-to-date ECI ready in case the HG612 dies, as mine did a week ago, you'll leave the ECI connected.

Only you can decide. My choice would be to wait for the update, then a few days later compare the results they both give. There could be a change from how they were pre-G.INP.

After emailing Zen regarding the issue yesterday, I received a reply from them.

Zen are aware of the issues affecting ECI modem and G.INP.

Here is the quote from their reply:

"Unfortunately, we are seeing problems being reported when the modem on a line does not support G.INP. These lines automatically have interleaving applied, even if they previously did not require it. This can result in lower sync rates and high latency.

Connecting a device compliant with G.INP should see an improvement. The only Zen supplied device that is not compliant is one type of ECI modem, which would need a firmware update to ensure compliance. Unfortunately you do appear to have this modem on your line."

They said BT are remotely sending out Firmware updates to these devices and will take few weeks to process.

Hope this helps people who are on Zen.

I have a HG612 3B modem and installed the unlocked SP08 firmware (BT Agent untouched and not deactivated), but don't know if I should disconnect ECI and connect the HG612 or wait for the firmware update for the ECI Modem

I wouldn't hold my breath on that happening , as according to a BT openreach source engineers are having to order a DLM reset to remove the G.inp before the modem is able to recive a firmware upgrade remotely, Unless they are planning to reset all lines that are on Huawei cabs ? as there is probably no way for them to know what modem is in use , of course ISP's are scared of getting charged by OR for a right when tested visit results

I would connect the HG612 now and when the forums start saying an ECI update is available, reconnect the ECI to get it updated.

Are you saying you have had the ECI modem updated?

I really can't see why BT can't create the update, put it in a file and the end user can do it..

Cheers Knight01 good to know something's being done.

As I understand things (via friendly BT bod on Kitz, and I'm starting to sound like a cracked record) it goes like this. BT auto update ECI modem firmware and then enable G.INP (if required). From this point non-updated ECI firmware will no longer work which can only be sorted by having the DLM reset.

So in theory, I don't think what you are suggesting will work unless the timing is spot on...

Will people be able to do this if their ECI modem is locked though?

BT have supplied zillions of ECI modems to customers, they MUST have thought all of this through?

That's what I was going to point out. Once the forums start reporting it, any particular user's line may already have been re-done.

I thought I kept saying I had, and received, an HG612?
