Table 4–7 Continued
Result Description
Code
LAYER 1 BRI
Provisioning error
on facility
LAYER 2 BRI
Provisioning error
on facility
LAYER 3 BRI
Provisioning error
on facility
Testing was not
performed on this
facility because no
other Layer 3
initialized facility
was available in
the time allowed
for testing
Corrective Action
Examine the wiring for the line, ensuring that all connections
have been closed. Rerun the test if a wiring problem is
identified. If the problem persists or if there is no wiring
problem identified, swap the DSL and its administration to
another port on the board.
If the problem follows the DSL, contact the LEC.
If the problem remains on the original port, mark the port
defective and replace the 800 NI-BRI board.
Layer 1 is established. Unplug the connector and replug it
into the same port. Rerun the test. If the problem persists,
contact the LEC.
Possible causes of this problem are:
The DSL is provisioned with only one active DN (rather
than two) at the CO
Two lines are administered when only one line is provided
by the CO.
Check that the facilities are administered properly and rerun
the tests if you made any corrections.
Layers 1 and 2 are established.
This result indicates that the CO does not do Layer 3
initialization. This error may not affect service, but the LEC
must be contacted.
Layers 1, 2 and 3 are established. Correct the known
problems on the other facilities and rerun the test.
