Coax R/W Test
This test displays a pattern on the screen as shown below. The test continues to run until the
terminal is powered off or varied offline and back online at the terminal. The MCC card is
tested for data integrity. If a failure occurs, the MCC card should be replaced. A successful
test is indicated by the data remaining on the screen the same as when the test starts. A failure
will result in some of the data skewing to other locations on the screen. The test should be run
for at least three minutes. This test only needs to be executed on one port of an MCC board.
Once the results of the test have been determined, you will need to turn the unit off.
