Internal Looparound Test (#135)
This test is destructive.
The Internal Looparound Test is run by looping the transmitted DS1 bit stream
back into the UDS1’s board receiver. The loop occurs just before the DS1 facility
interface. The test is highly destructive and can only be initiated by a system
technician-demanded
reset board UUCSS
command.
All trunks or ports on the UDS1 Interface circuit pack must be busied out via the
system technician
busyout board
command before running the Internal
Looparound Test. When the Internal Looparound Test is initiated, maintenance
software sends appropriate messages to the UDS1 Interface circuit pack to start
the test. The test uses the Tone Generator and Tone Detector to exercise a bit
pattern consistency test for all ports. If the transmitted and received bit patterns
on a trunk or port are different, the test fails.
When the test is complete, the maintenance software sends a stop loop around
message to the UDS1 Interface circuit pack to put the circuit pack back into the
normal operation mode. All trunks or ports of the UDS1 Interface circuit pack are
restored to the in-service state after the
release board
command is entered.
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.
