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.
The possible causes of this problem are:
The DSL is provisioned with only one active
DN (rather than two) at the CO.
Two lines are programmed when only one
line is provided by the CO.
Check that the facilities are programmed
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.
