Code Result Description / Recommendation
20MM FAIL The failure codes only apply to a system equipped with an ATM Switch. The
letters "MM" refer to the distant or far-end EPN, and "NN" to the near-end
ATM-EI under test.

30MM FAIL The failure codes only apply to a system equipped with an ATM Switch. The
letters "MM" refer to the distant or far-end EPN, and "NN" to the near-end
ATM-EI under test.
The test failed for the first connection from the ATM-EI board under test to
another EPN, and the test tone was detected correctly in the forward direction
(data sent from the EPN where the circuit pack under test resides was detected
correctly in port network MM, but not the opposite direction).
1. Test the active Tone-Clock on the "MM" EPN and the EPN where the
2. Ensure that the ATM address of the ATM-EI circuit pack under test
3. Run Test #241 on the active ATM-EI in port network MM. If this test fails

port network MM was detected correctly in the EPN where the circuit pack
under test resides, but not the opposite direction).
ATM-EI under test resides (test tone-clock UUCSS). This determines if
dial tone is supplied.
matches the ATM address on the ATM switch for the port to which this
circuit pack is connected. Refer to ATM Installation, Upgrades, and
Administration for Avaya MultiVantage Solutions book for the procedure to
check the ATM port address on the ATM switch.
with Error Code 20NN or 40NN, go back to step 2.
If the address was the same, replace the active ATM-EI circuit pack on port
network MM.
If this test fails with Error Code 10NN or 30NN, replace ATM-EI circuit pack
with the initial problem.
