Description / Recommendation
3 or 4 FAIL These failure codes only apply to a system equipped with a Center
Stage Switch. They indicate that the test aborted or failed for the first
connection from the EI board under test to another PN, and that the test
tone was detected correctly in one direction, but not the opposite
direction when the connection was between the EI board under test and
a different PN than was used in the first connection.
1. Run the test for the active Tone-Clocks on the PNs for which the
defective EI board provides a link. This determines if the dial tone
is being supplied.
2. Perform the Fiber link fault isolation in Chapter 4: General
troubleshooting in Maintenance Procedures for Avaya Aura
Communication Manager, Media Gateways and Servers
(03-300432).
FAIL The following failure codes only apply to a system equipped with an ATM
Switch. The letters “MM” refer to the distant or far-end PN, and “NN” to
the near-end ATM-EI under test.
10MM FAIL The test tone was detected correctly in forward direction (data sent from
the PN where the circuit pack under test resides and detected correctly
in port network MM), but not the opposite direction.
20MM FAIL The test tone was detected correctly in reverse direction (data sent from
port network MM was detected correctly in the PN where the circuit pack
under test resides), but not the opposite direction.
30MM FAIL The test failed for the first connection from the ATM-EI board under test to
another PN, and the test tone was detected correctly in the forward
direction (data sent from the PN where the circuit pack under test resides
was detected correctly in port network MM, but not the opposite
direction).
40MM FAIL The test failed for the first connection from the ATM-EI board under test
to another PN, and the test tone was detected correctly in the reverse
direction (data sent from port network MM was detected correctly in the
PN where the circuit pack under test resides), but not the opposite
direction.
