ATM-EI (Expansion Interface Circuit Pack)
Issue 1 June 2005 551
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 PN, 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 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).
1. Test the active Tone-Clock on the “MM” PN and the PN where the
ATM-EI under test resides (test tone-clock location). This
determines if dial tone is supplied.
2. Ensure that the ATM address of the ATM-EI circuit pack under test
matches the ATM address on the ATM switch for the port to which this
circuit pack is connected. Refer to for the procedure to check the ATM
port address on the ATM switch.
3. Run Test #241 on the active ATM-EI in port network MM. If this test
fails with Error Code 10NN or 30NN, 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 20NN or 40NN, replace ATM-EI circuit
pack with the initial problem.
