m. The board is receiving data from the bus faster than it can distribute the
data to its endpoints, causing the FIFO RAM buffer to overflow. This error
can occur occasionally due to the statistical sizing of the buffers. If it occurs
frequently, it may indicate a LAPD parameter mismatch. LAPD should
recover from this problem, but it may degrade the performance of the LAN
bus.
When this error is reported, maintenance reads and clears the board
counter and logs the problem in the maintenance error log.
n. Bad translation RAM detected, but the call continues by using another
translation location. The circuit pack reports this error when it cannot
update NPE/NCE memory and read it back. This error is not
service-affecting and can be ignored, but can lead to other types of errors
against this circuit pack.
System Technician-Demanded Tests: Descriptions
and Error Codes
When inspecting errors in the system, always investigate tests in the order listed
below. By clearing error codes associated with the Control Channel Loop Around
Test, for example, you may also clear errors generated from other tests in the
testing sequence.
Control Channel Loop Around Test (#52)
Refer to the repair procedure described in the “XXX-BD (Common Port Circuit
Pack)” section.
NPE /NCE Audit Test (#50)
Refer to the repair procedure described in the “XXX-BD (Common Port Circuit
Pack)” section.
SAKI Sanity Test (#53)
This test is destructive.
Refer to the repair procedure described in the “XXX-BD (Common Port Circuit
Pack)” section. This test is only run as a part of a reset board procedure.
