to drop, but any data displayed on the terminal while the test is running will be
lost.
The EPN Maintenance circuit pack has 3 separate serial interfaces:
■ One to the management terminal which is tested by Test #228
■ One to the active EI circuit pack which is tested by Test #229
■ One to the standby EI circuit pack which is tested by Test #229

Result Description/ Recommendation
1000 ABORT System resources required for this test are not available.
2000 ABORT Response to the test was not received within the allowable time period.
2033 ABORT Internal system error.
1. Retry the command at 1-minute intervals a maximum of 5 times.
2034 ABORT Background EPN Maintenance circuit pack maintenance is running the MGR I
Channel Local Looparound Test.
1. Wait 30 seconds and retry the test a maximum of 5 times.
22801 ABORT Test disabled via software patch.
FAIL Test failed which means the EPN terminal is not usable.
1. Run the test three more times. Replace the EPN Maintenance circuit pack if
the test continues to fail.
PASS The serial interface circuitry on the EPN Maintenance circuit pack which controls
the EPN-connected terminal is functioning properly. If there are still troubles with
the EPN G3-MT terminal, the problem may be one of the following:
1. The EPN-connected terminal is not configured properly. The connection
between the terminal and the EPN Maintenance circuit pack must be set up
at 9600 baud.
2. The serial link from the back of carrier A to the EPN terminal may be
defective. The serial link consists of the connector on the back of carrier A
labeled TERM and the ribbon cable running to the terminal.
3. The terminal may be defective. Try another terminal.
4. Since this test is not 100 percent accurate, there may still be problems with
the EPN Maintenance circuit pack.
