Using the facility test calls feature, you can use a voice terminal to make test calls to specific trunks, time slots, tones, and tone receivers within the system. The test call verifies that the accessed component is functioning properly. To use this feature, it must be enabled on the Class of Restriction screen, and you must know the facility test call access code. The code can be retrieved by entering display feature-access-codes. The system displays the code on page 1 of the screen output.

The test call descriptions mentioned below are for voice terminal users.
