Avaya 03-300430 User Manual

- If it is not clear which port board may be at fault, or maintenance is being performed 

remotely, verify that the EAA is not at fault by executing a PNC interchange. If the 
interchange solves the problem, then the EAA is faulty. 

- If the problem persists after the interchange, but TDM bus maintenance finds no 

problem, then the port board is faulty.

When a PNC interchange takes place, an error is logged against PNC-DUP with a code that 
conveys information about the cause of the interchange and which PNC became active. There 
are no alarms associated with PNC-DUP errors. There should be an alarm against the PNC 
component that drove the interchange. 
There are no PNC-DUP test sequences. Use status pnc to see information regarding the 

status of the PNCs. 
The information in the following tables helps identify areas of the Alarm Log to investigate in 
order to find the source of the problem.
