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 port network (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 EPN, and the test tone was detected correctly in the forward
direction (data sent from the port network in whic h the circuit p ack under
test resides was detected correctly in port network MM, but not the opp osite
direction).
1. Use the status system all command to determine the active
Tone/Clock.
2. Test the active Tone/Clock on the “MM” PN and the PN in which the
ATM-EI under test resides (test tone-clock UUCSS). This determines if
dial tone is supplied.
3. 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 the ‘‘ATM Tips’’ section in Chapter 5
for the procedure to check the ATM port address on the ATM switch.
4. Run this 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.
