Greetings all.

I've got four very old ITT 400E's in my 1A2 systems that are working fine. I wanted to get an extra or two to have around just in case.

I got several others to test out--two used and two brand new. But those four do not fully work. They will activate the line light when I pick up the line. But hey will not flash the the light when a call comes in, nor will they put the line on hold.

Having four working cards and four working slots to test these faulty ones, I'm certain the only thing it could be is the cards themselves. I've checked cards to see if their straps and jumpers are set up the same way as the working cards. As far as I can see, they are.

So here's my question. Anyone ever heard of this particular issue? Is it something that can be fixed by moving any of those straps/jumpers around, or does it really mean these things are doorstops?

Thanks much for your thoughts.
