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

Error type 1: disagreement between this switch and the terminal adapter at the other end of the connection with regard to the ISDN call state of the PRI endpoint port. This switch will automatically try to recover by clearing the call (the call will be torn down). Use status pri-endpoint extension to determine the state of the port.

When running the short test sequence, note the results of the Call State Audit Test 257.

Error type 15: software audit error that does not indicate any hardware malfunction. Run the short test sequence, and investigate associated errors.

Error type 18: the PRI endpoint port has been busied out by busyout pri-endpoint extension or busyout port location. No wideband calls can be made to this port, although wideband calls can still be made to other ports within this PRI endpoint if they are in service. Release the port with release port location.

Error type 129: the far-end terminal adapter changed its ISDN service state to out-of-service or maintenance. This may be a temporary condition due to testing of this port by the far-end terminal adapter or a hardware problem with the port. Outgoing calls to the terminal adapter will not be allowed over the port, although calls can still be made to other ports that are in service within the same PRI endpoint. To investigate the status of the port, enter status pri-endpoint extension.

Error type 130: the circuit pack has been removed or has been insane for more than 11 minutes. To clear the error, reinsert or replace the circuit pack.

Error types 257 and Error types 769: disagreement between this switch and the terminal adapter at the other end of the connection with regard to the ISDN service state of the PRI endpoint port. The switch will automatically try to recover by performing a service state audit. Use status pri-endpoint extension to determine the state of the port.

When running the short test sequence, note the results of the Service State Audit Test 256.

Error type 513: This port is not recognized by the far-end terminal adapter. Investigate the PRI endpoint administration for both the switch and the terminal adapter, and make sure they agree.

Error type 1281: The Conference Circuit test (#7) failed on this port. See Conference Circuit Test 7 for repair procedures.

Error type 1537: The NPE Crosstalk test (#6) failed on this port. See NPE Crosstalk Test 6 for repair procedures.

Error type 1793: failure of the UDS1 Interface circuit pack. Run the short test sequence and note the results of the Signaling Link State Audit Test 255.

Error type 3073: Two Service State audit attempts have failed, see Service State Audit Test 256. The port will not be usable for any outgoing calls to the terminal adapter until the test passes and the port state is changed to in-service. Incoming calls from the terminal adapter will be accepted over this port, and other ports in the PRI endpoint can still be used for both incoming and outgoing calls to and from the terminal adapter.

Error type 3585: the switch received an ISDN RESTART message for an ISDN port that is not idle. Because calls are not typically cleared with the RESTART message, this Error type may be associated with a dropped call report from a user.

The following Aux Data values for Error type 3585 represent the port’s ISDN call state at the time the unexpected RESTART request was received from the terminal adapter. This information can be useful if dropped calls are being reported by users of the PRI endpoint. Aux Data values that do not appear below can be ignored.
