TBRI-PT (ISDN Trunk-Side BRI Port)
Issue 1 May 2002

555-233-143
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
(R6.2 and higher).
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.
i. Error Type (1538) — This error occurs when a frame with a bad CRC is
received by the BRI trunk board. This error only occurs on a system that
switches the packet implementation of the D channel over the TDM bus.
This error indicates an off-board problem related to the packet
implementation of the TDM D channel (R6.2 and later).
j. Error Type (1793) — The BRI Port Local TDM Loop Around test (#619)
failed. Run the long test sequence, and pay particular attention to the
results of the BRI TDM Port Loop test (#619).
