40MM

FAIL

Failure code only applies 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 reverse 
direction (data sent from port network MM was detected correctly in the PN 

where the circuit pack under test resides), but not the opposite direction.

1. Test for the Active Tone-Clocks on port network  MM and the PN where 

the ATM-EI under test resides.  This determines if dial tone is 
supplied.

2. Ensure that the ATM address of the active ATM-EI circuit pack in port 

network MM 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 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.

PASS

Tone successfully transmitted in both directions.  Both ATM-EI boards and 

their lightwave transceivers are functioning properly.

NO 

BOARD

No board was detected by the test.

1. Resolve either wrong board (Error 125) or no board (Error 131) 

issues.

2. Check that the board is properly translated and inserted.  If so, check 

for hyperactivity (Error 1538).  If hyperactive, use reset board 
location.

3. Run the test again.  If it fails, the ID chip on board could be bad.  

Replace the board and retest.
