I need help asap pls, everything was ok on the norstar, all of the sudden when we hit 9 to dial out before I continue dialing the rest of the digits everybody in the office gets No Free Lines, no calls coming in either, this is a mics 4.1 with a t1/pri, i looked at the sys test log alarm, sys admin log alarm and net evt log alarm they're all 42-0 at the same time, there is combo card installed and t1 card has an amber led on under the circle with the arrow coming in, the one with the triangle and 2 semi-circles on its right side. If someone can point to what the problem might be I would appreciatte it, thanks alot.
