Error type 0: Run the short test sequence first. If every test passes, run the long test sequence. See each appropriate test’s description, and follow its recommended procedures.

Error type 1: Level 1 Status inquiry failed or the BRI circuit pack detected that Level 1 was deactivated on the port. The Aux Data field contains one of the following values:

See the repair procedures for Level 1 Status Inquiry Test 621. If the alarm does not clear, verify the status of the personal computer/server. This could be a customer network issue and not a board problem.

Error type 513: The circuit pack is having problems transmitting data to the packet bus. This error occurs when the packet bus transmit FIFO buffer overflows and most likely indicates a hardware problem. Use troubleshooting procedures for both on-board hardware problems and potential off-board packet bus problems.

Error type 1537: The port received an invalid frame over the D-Channel. This error is most likely because of a problem with the wiring to the set or adjunct, interference on the wiring because of a noise source, or no termination (an open circuit). It usually does not indicate a problem with the circuit pack.

Error type 3841: 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.

Error type 3844: The circuit pack detects an overflow of its receive buffers. Run the long test sequence, and note the results of the Receive FIFO Error Counter Test 625.

Error type 3845: The BRI Port Local LAN Looparound Test 618 fails. Run the long test sequence, and note the results of Test #618.

Error type 3846: The Terminal Endpoint Identifier (TEI) 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 ensure that both are using the same TEI.
