to drop, but any d ata displayed on the ter minal while the test is running will be lost.The EPN Maintenance circuit pack has 3 sep arate serial interfaces:
■One to the management terminal which i s tested by Test #228
■One to the active EI circuit pac k which is tested b y Test #229
■One to the standby EI circuit p ack 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 Looparoun d 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 usab le.
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 func tioning prop erly. If there are still trouble s 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 d efective. Try another terminal.
4. Since this test is not 100 percent accurate, there may still be problems with
the EPN Maintenance circuit pack.
