Checking carrier link protection switching
To verify that the carrier link protection switching is operating correctly,
conduct the following tests with carrier links:
•
forced carrier failure (disconnect carrier link at the I/O panel)
•
forced switchover
Note:
This test can be conducted only when carrier 2 is configured as
a spare carrier link.
If both carrier 0 and carrier 1 are faulty, carrier 0 will always have
sparring priority over carrier 1.
