Only one LED per port? Maybe multicolor, otherwise I wonder if the switch will report the speed.
As long as the port lights on link, should be good enough I think for the test. The BT box if I remember right did not show "link" light when the daphile box was connected.
I'm never going to get over pricing on this stuff. I recall a company called Grand Junction I think it was. First switch instead of a hub to reduce collisions. I think the unit had 16 ports. We paid 5 or 6 grand for it if I remember right. We were having high collision rates on our network of maybe 50 sun boxes and a few pc's. We carefully picked which machines (file servers, machines running regressions, high value developers) got these new fast ports and who got stuck on the old hubs. This was around 1994. And this was probably all 10MB. Been so long I don't remember. I just remember thinking how cool, the box stores the packet and forwards it only to the correct port(s) and it can be loading new packets from multiple ports at the same time.

It only bloody worked! Fantastic!
@mikeAtx - thanks so much for the solution - everyone else thanks for weighing in and helping me work through this logically!
IIUC the cause really was that the ends could not agree on common speed, and one of them is 100Mbps only (the daphile one, IIUC).
Congrats, really I am surprised. Never heard of 1G only ports. Must have saved BT a couple pence. It works though, that's what matters.
