I just purchased a PCS phone system and installed it. How would i know if it has additional capacity for additional phones in the office. Thx.

Check with the folks you purchased it from.

It is based on the old Vodavi DHS system. I think it might have a capacity of 9 lines & 24 phones if you have the right cards in it. I think it started out as a 3 X 8.

Go to the Vodavi forum and search "PC Digital" for some additional information. You also might try a search in the "Other Systems" forum.

There were 2 PCS Digital systems. If it's the small one, which is the most likely, there's cards on the left that support 3 lines by 8 phones each, max of 3 cards.

The larger one is rather scarce and a little more difficult to explain the card layout.
