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 p attern.
The test is highly destructive and can only be initiated by a system technician
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 TN767E circuit pack.
All trunks or ports on the DS1 Interface c ircuit pack must b e busied out via the
system technician busyout board comma nd 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 th is single bit error
should increment the bit error c ount of the loopbac k/span test by one.

BOARD The test could not relate the internal ID to the port (no board).
This could be due to incorrect translatio n s, no board is inserted , an incorrect
board is inserted , or an insane board is inse rted.
1. Check to ensure that the board translations are correct. Use the add ds1
UUCSS command to admini ster the DS1 interface if it is not alread y
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.
