NTAK79/NTBK50 power on self-test
When power is applied to the NTAK79/NTBK50 2.0 Mb PRI circuit card, the card performs a
power-on self-test. The self-tests verify the operation of most of the on-board hardware.
If all the self-tests pass, the upper five LEDs blink simultaneously three times. If any of the self-
tests fail, the LEDs do not blink. Only the OOS LED illuminates. The corresponding error code
is then printed on the TTY.
Self-test error codes
for the NTAK79/NTBK50 2.0 Mb PRI. These codes can be returned on card power-up in the
form "DTA105 L X" (where X is the failure code), or during a self-test procedure in LD 60 as
"DTI009 L X" (where X is the error code).
Failure codes 1-14 are hardware failures on the NTAK79/NTBK50 card. Codes 15-16 might
be due to carrier span problems or lack of loopback activation at the far end.
