I should have been more clear. What I was getting at is what I am saying

might break the rest of your span. I have seen people make the assumption
that they can safely turn off all the modems on a card thinking that it
would not have any adverse effect on the whole span.

I would never reccomend anything of the sort. Nor do I think anyone else
would. Although I am sure there are a few PM3-1s out there with only 1
