The reported error types correspond to the following detected errors:
i. These error types are reported when the following errors are detected:
j. These errors indicate that the circuit pack is having problems transmitting
data to the Packet Bus.
1293 On-board auxiliary processor insane
1294 Internal memory access error
1537 Frame overrun at Packet Bus interface. This condition may be
caused by 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 are alarmed, refer to the repair procedures
for those maintenance objects.
1538 Circuit packet is hyperactive; that is, it is flooding the switch
with messages sent over the control channel. The circuit
pack is taken out-of-service when a threshold number of
these errors is reported to the switch. Clear the alarm via the
following commands: busyout board PCSS, reset board
PCSS, test board PCSS long clear, release board PCSS. If
the error recurs within 10 minutes, then replace the circuit
pack.
1793 Parity errors are detected when transmitting data to the
Packet Bus.
1794 Overflow of Packet Bus transmit buffers has occurred.
1795 Circuit pack cannot find end of frame when transmitting to
Packet Bus. Clear the alarm via the following commands:
busyout board PCSS, reset board PCSS, test board PCSS
long clear, release board PCSS. If the error recurs within 10
minutes, then replace the circuit pack.
2306 This error occurs when the circuit pack detects an error in a
received frame from the packet bus. These errors are 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 Checking (CRC), is greater than the
maximum length, or violates the link level protocol.When bus
parity errors are reported, the LANBIC Receive Parity Error
Counter Test (#595) should be performed to determine if the
condition had cleared. Refer to the "PKT-BUS (Packet Bus)"
Maintenance documentation to determine if the problem is
isolated to this circuit pack or if the problem is caused by
Packet Bus faults.
