We had the same issue w/ a CT-3 cards in a 7500 series coming off of a Mux
w/ about 8 feet of cable. I believe the solution that we finally hit on was
to use a length of 75 feet of Coax w/ 12 DB attenuators on the send/receive
side. Since that time, we've have -0- issues with it.

BTW.. we ended up using a combination of after-market attenuators and some
radio shack coax adaptors for our solution. It's been stable for at least
1.5 years since..
