Inject Single Bit Error Test (#1215)
This 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 pattern.
The test is highly destructive and can only be initiated by a system technician
demanded
test ds1-loop PCSS inject-single-bit-error
command. An attempt to
use this command will be rejected if none of the three long-duration DS1
loopback/span tests (CPE Loopback Jack Test, Far CSU Loopback Test,
One-Way Span Test) are active on a TN767E circuit pack.
All trunks or ports on the DS1 Interface circuit pack must be busied out via the
system technician busyout board command before running the Inject Single Bit
Error Test.
The
list measurements ds1 summary
command displays the number of bit errors
detected (
Loopback/Span Test Bit-Error Count
field). Injecting this single bit error
should increment the bit error count of the loopback/span test by one.

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. Check to ensure that the board translations are correct. Use the add ds1
PCSS command to administer the DS1 interface if it is not already
administered.
2. If board was already administered correctly, check the error log to
determine if 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, 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 link between the internal ID and the port.
