OPS analog line card - faceplate

The faceplate of the card is equipped with a red LED. When an NT1R20
OPS Analog Line Card is installed, the LED remains lit for two to five
seconds while the self-test runs. If the self-test completes successfully, the
LED flashes three times and remains lit. When the card is configured and
enabled in software, the LED goes out.
