BCM 450 all of a sudden my ASM 8 in the main cabinet shows 'enabling' No dial tone the ports show 'unequipped' I have not been on site yet but I did software disable the card and re-ebable. No change. I then had customer power down the main cabinet. No change. Any ideas? I know it is not recommended to remove card with power on but I have heard from many techs you can reseat an ASM while system is up
