c. The port received an invalid frame over the D channel. When the CRC

(cyclical redundancy check) 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 one minute. If 5 more CRC errors are received within 15 minutes of the

last 5, 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

d. This error occurs when a Layer 1 Transmission error is detected for the

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 pack detects an overflow of its 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 TEI (Terminal Endpoint Identifier) administered for the ASAI endpoint

most likely does not match the TEI administered in the ASAI adjunct.

Check the switch administration of the TEI against that of the adjunct, and

make sure that both are using the same TEI.

Check the wiring to the endpoints or the adjunct.

If the problem persists, replace the endpoints or adjuncts.
