troubleshooting procedures. The BRI-PORT Alarm Level for the error with
Aux Data 0 is "MINOR," and the
ABRI-PORT/ATT-PORT/LGATE-PT/ATTE-PT Alarm Level is "MAJOR."
e. This error occurs when the NPE Crosstalk Test (#617) fails. Run the Long
Test Sequence, and pay particular attention to the results of Test #617.
f. This error occurs when broadcast signaling links associated with this port
have too much link establishment related traffic. This could occur if an
endpoint on this port is sending link establishment traffic on a port level
broadcast link, or if there are Level 1 problems on the port. Check the
error logs for Level 1 errors. If Level 1 problems exist, follow the repair
procedures listed for test #621. Software will suspend activity to this port
for 75 minutes when the port is alarmed due to this error (note that service
suspension does not occur if the port is an
ABRI-PORT/LGATE-PT/ATTE-PT/ATT-PORT). If this problem persists,
replace the endpoint or endpoints associated with this port. If replacing
the endpoints does not fix the problem, follow normal escalation
procedures.
g. This error occurs when the port receives an invalid frame over the
D-channel. When CRC errors exceed five within 15 minutes, the port is
taken out of service for five seconds. If five more CRC errors are received
within 15 minutes of the first set of five errors, the port is taken out of
service for one minute. If five more CRC errors are received within 15
minutes of the last five, the port is taken out of service for 15 minutes.
This error is most likely due to a problem with the wiring to the set or
adjunct, interference on the wiring due to a noise source or no termination
(an open circuit). It usually does not indicate a problem with the circuit
pack.
■ Check the wiring to the endpoints or the adjunct.
■ If the problem persists, replace the endpoints or adjuncts, or
escalate the problem.
h. This error occurs when the BRI Port Local TDM Loop Around Test (#619)
fails. Run the Long Test Sequence, and pay particular attention to the
results of Test #619.
There are no Test to Clear Values for the following error types. The error
types are simply provided as additional data that may prove useful while
troubleshooting.
i. This error occurs when a Layer 1 Transmission error is detected for the
port. Run the Long Test Sequence, and pay particular attention to the
results of the Layer 1 Transmission Error Counter Test (#624).
j. A BRI port supports up to three Terminal Endpoint Identifiers (TEIs). This
error occurs when the switch receives a request for a fourth TEI on a port.
Check the number of endpoints administered for this port.
