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 PCSS
and
reset board PCSS
commands. If the Circuit Pack Restart Test (#594)
passes, then the on-board circuitry is healthy. Retire the alarm with the
test board PCSS 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 by
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 maintenance objects. 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. 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 PCSS
,
reset board PCSS
,
test board PCSS long clear
,
release
board PCSS
. 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 if the condition has cleared. Refer to the
maintenance documentation to determine if the problem is
isolated to this circuit pack or is caused by Packet Bus
faults.
