Hello...I'm experiencing a line light problem with a ITT 1A2 Key system. The line 3 light will extinguish after a call then come back on for a couple seconds then go out. I've checked line polarity and replaced the line card with no apparent relief. Also, I just got a call tinight from the client telling me that the same line light was showing a hold condition when no one had put it on hold. The CO line was also emitting the pulsating beep showing an off hook condition. There were no phone off the hook. A
ny ideas out there?

I know this is a lot to ask for a new member of this board, but I need help.
