i. Error Type 1281: this error occurs when the BRI NPE Crosstalk test (#617) has failed. The
test will be repeated every 15 minutes until it passes. Follow normal trouble shooting
procedures for BRI NPE Crosstalk Test (#617). If this does not fix the problem, follow
normal escalation procedures.
j. Error Type 1537: the board received a bad Cyclical Redundancy Check (CRC) over the
D-chel. 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.
k. Error Type 1538: this error occurs when a frame with a bad CRC is received over the TDM
D-chel by the BRI trunk board. This error only occurs on a system that switches the packet
implementation of the D-chel over the TDM bus. This error indicates an off-board problem
related to the packet implementation of the TDM D-chel.
l. Error Type 1793: the BRI Port Local TDM Looparound test (#619) failed. Run the long test
sequence, and check the results of the BRI Port Local TDM Looparound Test (#619).
m. Error Type 2049: the BRI Layer 3 Query Test (#1243) has determined that the signaling link
is down (Layer 2). The test is repeated every 15 minutes until it passes.
n. Error Type 2305: the BRI Layer 3 Query Test (#1243) failed. The test is repeated every 15
minutes until it passes.
o. Error Type 2561: loss of Layer 1 in stable configuration. The BRI port is configured as
stable but the Trunk-side Layer 1 Query Test (#1242) failed 6 times within one hour. Change
the layer 1 stable field on the change bri-trunk-board screen
to n.
p. Error Type 3073: a frame of information had to be repeated or deleted. Slips usually occur
when the received bit rate is not synchronized with the TDM bus clock.
q. Error Type 3585: the circuit pack detected an overflow of its receive buffers. This error
occurs only a system that switches the packet implementation of the D-chel over the TDM
