Performing Self-test/local loopback
Before this test is run, disable the loop as follows:
1. Enter the following command in LD 60 to disable the NTAK10.
LD 60 DISL L CH
2. Enter the following command in LD 60 to run the self-test.
SLFT L (for the entire loop) SLFT L CH (for a specific channel)
Local loopback may also be performed on a per-channel basis without having to
disable the entire loop. In this case, only the tested channel must be disabled. The
procedure for this test is as follows:
3. Enter the following command in LD 60 to disable the 2.0 Mb DTI channel:
DISL L CH
4. Enter the following command in LD 60 to run the self-test:
SLFT L CH (for a specific channel
For self-testing individual channels, follow the same procedure as above, but use
the following commands:
DSCH C CH SLFT C CH (specific channel)

DTI009 loop ch DTI/PRI loop or channel failed hardware self-test. For DTI009 L M E, the
output data is
L
= loop M = N for NI microprocessor M = C for CI microprocessor E =
error code for debug purposes.
DTI009C ch DTI Card C or channel ch of Card C failed hardware self-test.
Error codes for NI microprocessor (M = N):
00 = NI self-test has finished.
01 = Undefined MESSOUT received.
02 = Problem with group 2 error handling (invalid level).
03 = NI to CI FIFO full (128 messages lost).
04 = CI-1 Micro failed to initialize on power-up.
05 = NI group 1 error handling - undefined condition found.
06 = Bad MESSOUT number 6 encountered.
07 = NI MESSOUT queue is full.
08 = NI MESSIN queue full.
