The STATUS LED indicates that the Lineside T1 card has successfully

passed its self test, and is functional. When the card is installed, this LED

remains lit for two to five seconds as 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. If the

LED flashes continuously, or remains weakly lit, replace the card.
