4. Go to the Port Performance Monitoring Screen by pressing P from the FRS Main
Screen. Analyze the register and status information provided to help determine the
cause of the problem.
5. Go to the Circuits Screen of the FRS card (which can be accessed by selecting Circ
from the FRS Main Screen). Verify that the affected circuit STATUS is up (indicated
by a “U”). If it is not up, this may indicate that an LMI is down in the far end of the
circuit. Highlight the affected circuit and type P and the performance registers for the
circuit will appear. Analyze the information provided to help determine the cause of the
problem.
6. Loopbacks are available on the “C” ports only. If a “C” port with an LMI is looped back
toward itself, the PORT TYPE must be nni for the loopback to function.
7. If the FRS card is determined to be faulty, replace it and return the faulty unit for repair
to the location specified by your distributor.
