Thanks for the prompt response. I might get lucky here. I used to have T1 tie lines on the system, the card was never removed from it's slot. This is my current slot config.
Carrier1
CPU, 800GSL, 408GSL, 408GSL, 408GSL, 408GSL
Carrier 2
100D, 016 R/G, 408GSL, 408GSL, 408GSL, blank
will I still need to re-arrange cards?
