c. Error Type (513): On-board hardware failure. The FIFO RAM buffers have
overflowed, indicating a hardware problem.
d. Error Type (514): Transmit FIFO Overflow - This error indicates that the
circuit pack is having problems transmitting data to the TDM D-Channel.
This error only occurs only a system that switches the packet
implementation of the D-channel over the TDM Bus. This error indicates an
on board problem related to the packet implementation of the D-Channel.
e. Error Type (769): The port is generating too many uplinks. The link is being
suspended.
f. Error Type (1025): An expired timer has created an unexpected event. The
timer could be any of the following:
g. Error Type (1281): This error occurs when the NPE Crosstalk Test (#617)
has failed. The test will be repeated every 15 minutes until it passes.
Follow normal trouble shooting procedures for NPE Crosstalk Test (#617).
If this does not fix the problem, follow normal escalation procedures.
h. Error Type (1537): The board received a bad Cyclical Redundancy Check
(CRC) over the D-Channel. This error is reported on a per-port basis.
When the CRC errors exceed 5 within 15 minutes, the port is taken out of
service for 5 seconds. If 5 more CRC errors are received within 15 minutes
of the first set of 5 errors, the port is taken out of service for 1 minute. If 5
more CRC errors are received within 15 minutes of the previous 5, the port
is taken out of service for 15 minutes.
This error is most likely due to a problem with backplane wiring, a noise
source, or no termination (an open circuit). It usually does not indicate a
problem with the circuit pack.
1. Check the backplane wiring.
2. If the problem persists escalate the problem.
