Has a 16 port digital station card and an 8 port station card, 4 port analog card, and 2 8 port CO cards.

Tried adding a 8 port digital extension daughter board to the 8 port station card and the ports never show up? Tried several daughter boards! Can I put a 16 port in place?
Could it be licensing?

Thank you In advance!

Take care,
Gary

What size is that CPU? That digital card will need to be able to grab 16 ports in a row. If there aren't any it will never work.

Its a CD-CP00+PZME50 all the cards slots in the chassis are taken up so maybe that is the problem. the last card is a trunk card and the 8 port digital card i need to add to is in the slot above it.

What you will probably need to to IF you have enough ports is delete both the last digital card and analog cards from your database. Replace the 8 port digital with a 16 card and then the analog station card. all the programming from port 25 on will be messed up.
