5. When the countdown values in the BP Switch IE of the beacon in slot 2 reaches 5
the test system also sends a BP Switch IE in slot 3 with a countdown value of 9
and a beacon slot offset of 12.
6. The superframe following step 5, the BP Switch IE of the beacon in slot 2 is sent
with a countdown value of 9 and a beacon slot offset value of 12. The BP Switch
IE of the beacon in slot 3 begins to countdown normally.
7. After the countdown value for either BP Switch IE reaches zero, the test system
ceases to send that beacon in any future superframes.
8. Stop analyzer capture.
Notes:
In addition to passing the normal background checks, the following points are manually
verified:
• After receiving the tester's beacon with a BP Switch IE, the DUT/INTD should
include a similar BP Switch IE in their own beacon and start counting down.
• Verify the countdown field of the DUT/INTD's BP Switch IE should be one greater
than that of the test system.
• Verify that the SF after a device's countdown hits 0, the DUT beacon should be in
its new slot (if its BP Switch IE had a non-zero Beacon Slot Offset) or should
rejoin "normally" if its Beacon Slot Offset was 0.
• The DUT and INTD are allowed to cease demonstrating operation and/or beacon
transmission during this test case once the BP Switch IE appears. Beacon
transmission and demonstrated operation must automatically restart without
manual intervention if either ceases.
Test Case 1.13: Maximum Beacon Slot Usage
This test verifies the DUT & INTD do not exceed the maximum beacon slot number of
96. The tester sends beacons sequentially incrementing the BPOIE to indicate fictitious
devices are occupying slots 3 – 95 forcing the DUT & INTD to relocate their beacons to
higher slots. It is allowed for devices to discontinue beaconing after occupying slot 20 or
higher.
Test procedure:
1. Start analyzer capture
2. Test system starts transmitting a beacon in slot 2. The BP Length is set to 12.
3. Standard test start-up sequence.
4. The test system modifies the beacons in slot 2 with a BPOIE indicating a device with
a DevAddr of 3 is occupying slot 3 and modifies the BP Length to 13.
