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 PN, and “NN” to the near-end 

ATM-EI under test.

6. The test tone was detected correctly in 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).

7. Test the active Tone-Clock on the “MM” PN and the PN where the 

ATM-EI under test resides (test tone-clock location).  This 

determines if dial tone is supplied.

8. Ensure that the ATM address of the active 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.

9. 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.
