NTAK09 DTI/PRI power on self-test

When power is applied to the NTAK09 DTI/PRI circuit card, the card performs a self-test. The
LEDs directly associated with the NTAK09 circuit card are DIS, ACT, RED, YEL, and LBK. The
clock controller LED is also included in the power on self-test.

NTAK20 power on self-test
The clock controller daughterboard LED is the second LED from the bottom on the faceplate
of the NTAK09 DTI/PRI card.
When power is applied to the NTAK20 clock controller, the LED is initially off for two seconds.
If the self-test passes, the LED turns red and flashes on and off twice.

Action
Top five LEDs light for eleven seconds.
Top five LEDs go out for one second.
If the self-test passes, the top five LEDs flash on and
off three times.
If the self-test detects a partial failure, the top five
