The Packet Interface Looparound test checks the packet-bus interface circuitry on this board.
The on-board LANHO chip sends a data stream to the bus, retrieves it back, and checks for its
consistency. If the data is consistent, the test passes; otherwise, it fails. The test aborts if the
specified PN’s packet bus has an active minor alarm or is out of service. This test runs as a part
of initialization, periodic or scheduled error analysis, and demand-test sequences. Figure 26
shows a schematic of the test.

Description / Recommendation
2000 ABRT Response to the test request was not received within the allowable time
period.
1. Retry the command at 1-minute intervals up to 3 retries.
2. If the test fails repeatedly, attempt to reset the circuit pack.
3. If the test continues to fail, replace the circuit pack.
2012 ABRT Internal system error
2100 ABRT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
ANY FAIL The transmitted data packet was not received correctly by the Packet
Interface circuit pack. The failure can be in the ATM-EI under test, the
DS1C-BD circuit packs, or the intervening Center Stage components.
1. Retry the command at 1-minute intervals up to five times.
2. If the test continues to fail, replace the circuit pack.
PASS The Packet Interface test passed.
