Ive been trying to program a dk 40i system with dkt 2020 sets after installing a new pdku2 station card. The new pdku 2 card has accepted all programming but the stations on the base cabinet will not accept co line programming. When programming those specific stations the system accepts the entries but does not take to the phone. Has anyone experienced this problem and can suggest what I should look for.

The system is maxed out on the station side and I did have issues with the ivp8 being in the slot 17 because when installing the pdku2 before the voicemail it shifted the station ports on the ivp8 and downed it from functioning. I have now placed the ivp8 into slot 15 and placed the pdku2 into slot 17 and everything worked with the exception of this problem with programming.

Did you recycle the dk after the swaps ?

Yes the system was powered down and back up again. The system takes the programming entries the co line appears but when you try to access the line nothing is there. But strangely when someone answers the call and places it on hold it can be picked up at that extension.

Try program 40. Maybe you dont have line access on those phones.
