Inject Single Bit Error Test (#1215). Thi s test is destructive.
The Inject Single Bit Error Test will cause a single bit error to be sent within an
active framed 3-in-24 test patte rn.
The test is highly destructive and can only be initiated by a system technic ian
demanded
test ds1-loop UUCSS inject-single-b it-error
command. An attempt to
use this command will be rejec ted if none of the three long-d uration DS1
loopback/sp an tests (CPE Loopback Jack Test, Far CSU Loopback Test,
One-Way Span Test) are active on a TN464F circuit pack.
All trunks or ports on the UDS1 Interface c ircuit pack must b e busied out via the
system technician busyout board com mand before running the Injec t Single Bit
Error Test.
The
list measurements ds1 summary
command disp lays the number of bit errors
detected (
Loopback/Span Test Bit-Error Count
field). Injecting this single bit error
should increment the bit error c ount of the loopbac k/span test by one.
PASS The One-Way Span test has successfully began transmitting a framed 3-in-24
test pattern. The test will continue to run until the system technician enters the
test ds1-loop UUCSS end-loopback/span-test
command or the
release board
UUCSS
command.
0NO
BOARD The test could not relate the internal ID to the port (no board). This could be
due to incorrect translations, no board is inserted, an incorrect board is
inserted, or an insane board is inserted.
1. Ensure that the board translations are correct. Execute the add ds1
UUCSS command to administer the UDS1 interface if it is not already
administered.
2. If the board was already administered correctly, check the error log to
determine whether the board is hyperactive. If this is the case, the board
is shut down. Reseating the board will re-initialize the board.
3. If the board was found to be correctly inserted in step 1, then issue the
busyout board command.
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
This should re-establish the linkage between the internal ID and the port.
