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 which the circuit pack und er
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 in which the
ATM-EI under test resides (test tone-clock UUCSS). 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 the ‘‘ATM Ti ps’’ sec tion in
Chapter 1 for the proc edure to check the ATM port ad dress on the
ATM swi tch .
3. 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-E I circuit
pack with the initial problem.
