Use status tti to see the TTI/PSA status screen and see if the TTI background maintenance task is active. If the TTI background maintenance task is active, the screen shows whether TTI ports are being generated or removed, the number of TTI-supported boards that have processed, and the number of TTI-supported boards that have not yet been processed. The screen also shows the elapsed time since the background maintenance task started.
To activate the TTI background maintenance task, enter y in the TTI field on the Feature-Related System-Parameters screen.
Use status psa to also see the TTI/PSA status screen. It shows that the status of PSA is dependent on the state of TTI.
