MG-BRI (BRI Trunk Media Module MM720)
Issue 1 June 2005 1591
e. Error Type 769: the circuit pack detects a program logic error. While no action is required,
this error can lead to other errors against this circuit pack.
f. Error Type 1025: the circuit pack cannot update and read back NPE/NCE memory. This
error can be ignored, but may lead to other errors against this circuit pack.
g. Error Type 1291: the MM720 BRI Media Module notifies maintenance software that it has
detected a parity error while accessing its dynamic RAM (that stores the board’s translation
information and downloadable application firmware). Maintenance software resets the
circuit pack.
h. Error Type 3586: the SPE software detects an excessive number of up-link messages from
the TN2185 board within a certain time period. To prevent the faulty board from flooding the
switch with data, the switch software takes the board out of service and alarms it. The
switch software also tells the Archangel to ignore up-link messages from the board.
When the board is alarmed due to this error, the switch software periodically puts the board
back in service and tells the Archangel to process up-link messages from the board. If the
problem still exists, the software takes the circuit pack out of service again. If the circuit pack
does not exhibit the problem for a certain time period, then maintenance software resolves
the alarm and the circuit pack is left in service.
i. Error Type 3840: the circuit pack received an inconsistent down-link message (a bad
header, port number, data, sub-qualifier, or logical link) over the Control Channel.
j. Error Type 3842: 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.
k. Error Type 3843: 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.
