One-Way Span Test (#1214)
This test is destructive.
2 FAIL The far CSU Loopback Test was not set up properly. The DS1 Interface circuit 
pack could not put the far-end CSU into loopback mode.
3 FAIL The far CSU Loopback Test was not set up properly. The framed 3-in-24 test 
pattern, generated by the DS1 Interface circuit pack and looped back through 
the far-end CSU, could not be detected by the DS1 circuit pack.
1. Retry 
t
est ds1-loop PCSS far-csu-loopback-test-begin.
2. If the Far CSU Loopback test continues to fail with this error code, the 
problem could be with the TN767E board, the far-end CSU equipment, or 
somewhere in between. Run test ds1-loop PCSS 
cpe-loopback-jack-test-begin to see if the CPE Loopback Jack test which 
is closer to the TN767E board is successful. (If a CPE Loopback Jack 
device is not being used, then run test ds1-loop PCSS 
ds1/csu-loopback-tests to see if these even closer loopback tests 
succeed). If the closer loopback test fails, follow the maintenance strategy 
associated with that loopback
  PASS The Far CSU Loopback test has successfully began executing. The test will 
continue to run until the system technician enters test ds1-loop PCSS 
end-loopback/span-test or the release board PCSS.

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.
