That is still the case. With the exception of multi-point lines which
could display either an 'M' or a 'D'.

It means that your font is displaying a '.' but it looks like a '-'!
I know that sounds like an April fool response, but in *every* case that
I've seen/heard of this (in Link Status, not the individual channel status)
it turned out to be the terminal emulator displaying an "extended" '.' -
so it *looks* like a '-'.
The '.' means that the physical layer is up, but the logical link is not.
Most often this is caused by invalid SPIDs here in the US - which doesn't
help you in the UK! Basically layer-2 is down, for whatever reason.
Did the first customer get the new P75 yet, and is it acting any better?
[If not - Is it at all possible that BT - or whoever - has just recently
upgraded their switches? (It would be possible that timing changes could
cause this for example)].
