BRI-PORT (ISDN-BRI Port), ABRI-PORT (ASAI
ISDN-BRI Port)
d. Error Type 513 – This error indicates that the circuit pack is having
problems transmitting data to the packet bus, thus affecting the
conveyance of signaling information over the D channel. With Aux Data
46222, this error occurs when the packet-bus transmit buffers overflow.
This condition probably indicates a hardware problem. The BRI-PORT
Alarm Level for the error with Aux Data 46222 is "MINOR/WARNING," and
the ABRI-PORT/ATT-PORT/LGATE-PT/ATTE-PT Alarm Level is
"MAJOR/MINOR/WARNING." With Aux Data 0, this error occurs whenever
the packet-bus transmit FIFO buffers overflow. This condition can be
caused by an on-board hardware problem as well as by problems on the
packet bus that disrupt the BRI circuit pack's ability to transmit data onto
the packet bus. Use troubleshooting procedures for both on-board
hardware problems and potential off-board packet-bus problems. See
''PKT-BUS (Packet Bus)'' on page 8-1230
Repairing Packet-Bus Faults'' on page 4-81
troubleshooting the packet bus. 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. Error Type 769 – 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. Error Type 1281 – This error occurs when a port's associated
broadcast-signaling links have too much traffic related to link
establishment. 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. Error Type 1537 – 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.
