system "housekeeping" question

[GUIsareapassingfad]

hello again o great oracle of telephony knowledge

so I had 10 analog "trunks" coming in to my system. they were from an earlier time and were deemed unnecessary, so I had them disconnected.
(I had to keep one to maintain my billing plan).
So now I have the TN's from those trunks but no lines. can I leave em that way? is it goiung to confuse the system? how do I determine if those numbers came up anywhere?
thank you.

Normally analogue trunks will be configured AUTO in the RDB and then against the TN would be ATDN which is the extension it lands on. It would be better to delete the unused trunks.
