Outgoing Voice Call Test

Place a voice call from the BRI line under test to either a working facility on the
system or to a phone on the premises that is connected to the Central Office
(CO).
NOTE:
The 800 NI-BRI module must be restored (removed from the Maintenance
Busy state) before performing this test.
Assign the BRI line to a button on an MLX display station.

If using a facility on the system as a destination, also assign the
destination facility to a button on another MLX display phone.
Press the button associated with the BRI line under test.

The red LED next to this button should be on and steady. If not, check
that the BRI line has been correctly assigned to this button.
Go off-hook by lifting the handset or pressing the speakerphone

button.
The red and green LEDs on this button should be on and steady. A dial
tone should be heard. If not, record that the outgoing voice call test has
failed.
Dial the destination number. (In a Centrex environment, it is

necessary to dial a 9 before the destination number.)
Verify the following results and note any failures:
Dial tone should be off after the first digit is dialed.
Verify that the originating end hears ringback after the last digit is
dialed and that the destination phone is ringing.
If either indication is absent, check that the dialed digits are those
of the destination Directory Number (DN).
If the destination telephone can display calling party number,
verify that the DN of the BRI line under test is displayed correctly.
If not, record that the calling party information displayed is either
incorrect or absent at the destination telephone.
