Avaya 03-300430 User Manual

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.  

shows a schematic of the test.

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.

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.
