Operations Interface Tests 9
The FT-2000 OC-48 Lightwave System provides the following inputs to test LEDs,
serial and parallel telemetry interfaces, and office alarms:
â– FAULT-Test-LED: This input lights the specified LEDs. The test consists
of one or more test cycles repeated as many times as specified. For each
test cycle, the LED(s) is lighted for 10 seconds, then turned off for 10
seconds. The LED(s) reverts to normal operation after the test is
completed. The PWR ON LED is always on if the bay is powered and
cannot be tested with this input.
â– FAULT-Test-Telemetry-Parallel: This input tests the operation of
the local parallel telemetry and miscellaneous discrete control output
points. Each test cycle activates the selected control output point(s) for 20
seconds, then clears the control output point(s) for 20 seconds. The control
output points revert to normal operation after the test is completed. This
input is not available at the FT-2000 OC-48 Repeater Bay.
â– FAULT-Test-Alarm: This input tests the audible and visible office alarm
outputs and their corresponding user panel LEDs (CR, MJ, and MN). The
test consists of one or more test cycles repeated as many times as
specified. The alarms revert to normal operation after the test is completed.
