Greetings Experts.

Do you know how can we find a new TAC in network?

What is predefined sequences?

Considering the current TAC.

Do you mean Core network guys pop-up a new TAC without informing RAN engineers?

No. I mean it should be some TAC in network that we do not know about it.

So I want to find them out which TAC is empy and use it for onw specific case.

I mean if we have one defined TAC then some sequence of it should be already available.

I’m looking for that sequence.
