I'm curious about BA DACS. I don't know if this is standard, but they
are the only telco who has also told me "we put a loop up on the DACS,
but sometimes it doesn't work ... so don't assume that it is a valid
test." And I have witnessed that same happening. If you can't create a
simple maintenance loop on BA's DACS, their choice of vendors does seem
questionable.
