PKT-INT (Packet Interface)
Maintenance Looparound Test (#886)
This test checks whether the Packet Interface can send and receive data
correctly. It establishes a LAPD link from a Packet Interface back to the same
Packet Interface and transmits and receives test data over that testing link. While
timing signals from the Packet Bus are used for the data transfer, the data itself is
looped around on the TN799 C-LAN circuit pack's Bus Bridge at the interface to
the Packet Bus and does not get sent over the Packet Bus. This test is run only on
the second instance of Packet Interface on the TN2402/TN798 Processor, since
the first instance cannot use the Packet Bus.

Description/ Recommendation
1. Use the display system-parameters maintenance command to identify
which C-LAN circuit pack is administered with the Bus Bridge. Verify that
the C-LAN circuit pack is present and is not alarmed.
2. Reset the Packet Interface using the reset packet-interface AS
command. Refer to the Packet Interface Reset Test (#889)
maintenance documentation for further action.
1. Try to retire the alarm associated with the Packet Bus. Refer to the Alarm
Log through the display alarms command. Refer to the maintenance
documentation for Packet Bus Maintenance for further action.
2. Retry the command when the alarm associated with the Packet Bus is
retired.
1. Retry the command at 1-minute intervals, a maximum of 3 times.
1. Retry the command at 1-minute intervals, a maximum of 5 times.
