ATM-EI (Expansion Interface Circuit Pack)
Issue 1 June 2005 549
10MM 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 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.
1. Test the active Tone-Clocks on the “MM” PN and the PN where the
ATM-EI under test resides (test tone-clock location). This
determines if a 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 ATM Installation, Upgrades, and
Administration using Avaya Communication Manager, 555-233-124,
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.
4. If the address was the same, replace the active ATM-EI circuit pack on
port network MM.
5. If this test fails with Error Code 20NN or 40NN, replace ATM-EI circuit
pack that had the initial problem.
