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 port network (PN), and “NN” to the
near-end ATM-EI under test.
The test tone was detected correctly in reverse direction (data sent from the
MM port network was detected correctly in the port network in which the
circuit pack under test resides, b ut not the opposite 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 active AT M-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 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.
