— This test verifies the operation of a large portion of the ATM-EI circuit and
packet paths, but does not verify the optical portion of the lightwave
transceiver. If this test passes, the ATM-EI circuit pack is functioning
correctly, but faults can exist in the lightwave transceiver. If the test fails,
the fault can be on the board. After the test results are reported, the ATM
framer is taken out of loopback.
NOTE:
This test can be run on active or standby ATM-EIs, but it is not
allowed if an ATM-EI is the Expansion Archangel.
