You do wonder don�t you, not one single report of any issue with the Openreach ONT�s ... and yet folk desperate not to use it for a supposed saving of a few ms .....
Correct about the detection possible, �they� knew there was no BBU connected. Can also put head end into discovery mode and see what�s attempting connection, and much more I daresay.

I assume those people worried not about milliseconds but microseconds have also researched infrastructure and thus are also latency wise already as close as possible to the gaming service they use, ie. living in a datacentre
The kicker is that games sometimes have lag compensation that attempts to level the playing field, so that sub 1 ms user can actually have a worse experience unless in a match where everyone else is sub 1ms.

Interesting one of BT's REIN bods a few years ago was wandering up and down my parents street looking at a device then back up again eventually he knocked on the door and said "One of your wireless CCTV cameras is spewing out loads of interference which is crippling your neighbour's ADSL so would you please replace it. My dad said well what if I don't and the engineer replied i'll report you and BT will take you to court and sue you.
So I guess he was full of BS to intimidate my dad into doing the right thing (he was going to anyway but he wondered what they'd do). After that I always assumed they'd come down on ppl like a ton of bricks if they were outputting disruptive signals like that.

TBH I don't think it would save that much latency, I rather like the ONT, its not ugly, its sort of hidden away and easy to get up if need be.
I have had loads of Modems in the past that I have had issues with, but have yet to have any issues with our ONT, which is working great.
Like I said I am not too sure how much latency people of FTTP would save by replacing the ONT shown below is a traceroute to the BBC site:
tracert -4 bbc.co.uk
Tracing route to bbc.co.uk [151.101.128.81]
over a maximum of 30 hops:

Trace complete.
Most of the Game Servers I connect to are EU Based Server like Blizzard's World of Warcraft Realm Servers I get between 6ms and 11ms.
So gaining a ms here an there wouldn't change much.

If I recall Blizzard's World of Warcraft has one which you set to your latency to their servers, it adds some input lag when used, but makes the game run smoother.
I use to use it when I use to play on they US Based Realm Servers which use to be between 250ms and 400ms when we were on ADSL 2+, with it disabled I was noticing the casting and actions misfiring due to latency lag, but with it enabled it was fine, well 80% of the time assuming the latency stayed the same.

Are you sure Openreach are just using the serial number not serial number + password?
Following on from this even if they are just using the SN when the ONT registers it'll have a MIB data sync mismatch. The OLT will require a full MIB sync. This will rather give away that it's not an Openreach ONT on the other end of the connection.
The MIB sync allows the OLT to discover hardware configuration and software capabilities of the ONT.
Openreach use this to determine when to push firmware updates to their ONTs.
Best hope Openreach neither use SN + password or are paying any attention to the MIBs being returned from ONTs.
Openreach are clearly using the SN, and at best a fixed password that is the same on all ONT's so not hard to replicate. Further these devices are all Linux based including all the SFP based ones. As such changing the MIB to match is trivial exercise. The simpler solution of course would be for Openreach to offer an SFP based ONT to customers that request one.

So you're also going to set up your own OLT to capture the password? Fair enough.
Do you know for sure that all the software and hardware information is in a simple text file, none of it pulled from, say, firmware, ROM or other binary blobs, and that even if you can modify it you won't break things?

With the new XGPON options allowing 1000mbps, how does this work with only 1 gigabit Ethernet port? Gigabit Ethernet is only about 6-700mbps, not 1000, so with the ONT having only 1 port it has to be either 10GbE, an SFP+ (GBIC slot) or use a LAG (bonded ports) to get true 1000mbps.
Otherwise we have an 'up to' fiasco again, and a lot of miffed people not seeing 4 digits on their TBB speedtests!

Just maybe they might supply a different ONT

I believe the new 1+1 ONT supports XGPON. If they were supplying a different ONT, it should appear in the BT SIN.
