True, but as they discontinued the previous trial due to hardware problems and AFAIK HH5A was a big part of that, what makes that any different today?
What makes you think it was the HH5A?
I don't think anyone has the slightest clue what modems resulted in the last trial being stopped.
It wasn't necessarily the modems that saw issues during the very 1st rollout.
Those modems saw increased latency and a drop in sync.
The last trial was stopped due to a bitswapping issues but that's the only details OpenReach gave.
My Home Hub 5A with OpenWRT on it couldn't hold a stable sync with G.INP but I believe the "official" firmware may do. Can't really see how they could roll it out if they hadn't fixed their own firmware.
That's assuming those in bold are 1 and the same entity.
Unless by the 2nd "they" you were referring to OpenReach and their ECI modem.
