FirstSource,
Do you get an alarm 114 showing the T-1 not being there and then it goes away after the system comes up all the way or does that alarm stay on your system all day?
You can go to the back of your system and see a T-1/E-1 card on the base cabinet and where there is a patch cord plugged in it should either have a green light or a flashing red light.
Thanks,
TE
