e. 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.
f. The TN2185 board 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.
g. Unable to write LAN Translation RAM Error (internal memory access error).
Translation RAM locations for the call connection attempt are not available,
and one or more RAM locations are bad due to a translation RAM
read-back error. Reset the circuit pack with the busyout board UUCSS
and reset board UUCSS commands. If the Circuit Pack Restart test
(#594) passes, then the on-board circuitry is healthy. Retire the alarm with
the test board UUCSS long clear command. If the Circuit Pack Restart
test (#594) fails, replace the circuit pack.
h. Frame overrun at Packet bus interface. Due to an on-board fault or to
faulty data received on one of the circuit pack’s external ports. If any of the
ports on this circuit pack is alarmed, refer to the repair procedures for those
MOs. If this error persists, maintenance software removes the board from
service; replace the circuit pack.
i. The circuit pack is has problems transmitting/receiving data to/from the
Packet bus.
j. Error Type (2305, 3330): A critical failure in the Circuit Pack’s Packet bus
interface. Possible causes include either a Packet bus fault or an on-board
fault, for example, the board received a bad CRC or invalid DLCI. If the
Packet bus is alarmed, see
‘‘Isolating and Repairing Packet-Bus Faults’’ on
. The number of ISDN circuit packs displaying this error
increases the probability of errors due to Packet bus problems.
1793
Parity errors are detected when transmitting data to the Packet bus.
1794
Packet bus transmit buffers overflow.
1795
Circuit pack cannot find end of frame when transmitting to Packet bus.
Clear the alarm with: busyout board UUCSS, reset board UUCSS,
test board UUCSS long clear, release board UUCSS. If the error
recurs within 10 minutes, replace the circuit pack.
2306
Error in a received frame from the Packet bus, most likely caused by a
packet bus problem, but may be due to a circuit pack fault. An invalid
Link Access Procedure Data (LAPD) frame error occurs if the frame
contains a bad Cyclical Redundancy Check (CRC). If bus parity errors
occur, run the LAN Receive Parity Error Counter test (#595) to
determine whether the condition has cleared. Refer to the
maintenance documentation to determine whether the problem is
isolated to this circuit pack or is caused by Packet bus faults.
