c. The port received an invalid frame over the D-channel. When the Cyclical
Redundancy Check (CRC) errors exc eed 5 within 15 minutes, the port is
taken out of service for 5 second s. 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 one minute. If 5 more CRC errors are received within 15 minutes of the
last 5, the port is taken out of servic e 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 d oes not indicate a p roblem with the circuit
pack.
■Check the wiring to the end points or the adjunct.
■If the problem persists, rep lace the endpoints or ad juncts.
d. This error occurs when a Layer 1 Transmission error is detected for th e
port. Run the Long Test Sequence and note the results of the Layer 1
Transmission Error Counter Test (#624).
e. This error occurs when the circuit pac k detects an overflow of it s receive
buffers. Run the Long Test Sequence and note the results of the Receive
FIFO Overflow Counter Test (#625).
f. This error occurs when the BRI Port Local LAN Looparound Test (#618)
fails. Run the Long Test Sequence and note the results of Test (#618).
g. The Terminal Endpoint Identifier (TEI) administered for the ASAI endpoint
most likely does not match the TEI administered in t he ASAI adjunct.
Check the switch administration of the TEI against that of the adjunc t, and
make sure that both are using the same TEI.
System Technician-Demanded T ests: Descripti ons
and Error Codes
Always investigate tests in the order p resented in the following tabl es when
inspecting errors in the system. For examp le, by clearing error c odes associated
with the NPE Crosstalk Test, you may also clear errors generated from other tests
in the testing sequenc e.
