e. The circuit pack cannot update and read back NPE/NCE memory. This
error can be ignored, b ut may lead to other errors against this circ uit pack.
f. The TN2185 board notifies maintenance software that it has detected a
parity error while access ing its dynamic RAM (that stores the b oard’s
translation information and download able applic ation firmware).
Maintenance software resets the circ uit pack.
g. Unable to write LAN Translation RAM Error (internal memory access error).
Translation RAM locations for the call connection attemp t are not available,
and one or more RAM locations are bad due to a translation RAM
read-back error. Reset the circu it pack with the busyout board PCSS and
reset board PCSS commands. If the Circ uit Pack Restart Test (#594)
passes, then the on-board c ircuitry is healthy. Retire the alarm with the
test board PCSS long clear command. If the Circuit Pac k Restart Test
(#594) fails, replace the circ uit pack.
h. Frame overrun at Packet Bus interface. Due to an on-b oard fault or by
faulty data received on one of the c ircuit pack’s external p orts. If any of the
ports on this circuit p ack is alarmed, refer to the repair p rocedures for
those maintenance objects. If this error persists, maintenance software
removes the board from service; rep lace the circuit pac k.
i. The circuit pack is has p roblems transmitting/receiving data to/from the
Packe t Bus.
j. Error Type (2305, 3330): A critical failure in the Circuit Pack’s Packet Bus
interface. Possible causes inc lude either a Packet Bus fault or an
on-board fault, for example, the board received a b ad CRC or invalid
DLCI. The number of ISDN circuit pac ks displaying this error increases the
probability of errors du e to Packet Bus problems.
1793 Parity errors are detected when transmitting data to the
Packe t Bus.
1794 Packet Bus transmit buffers overflow.
1795 Circuit pack c annot 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, replac e
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 pac k fault. An invalid Link Acc ess 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 documentatio n to determine if the problem is
isolated to this circuit p ack or is caused b y Packet Bus
faults.
