Troubleshoot the BRI Card
One status LED and fifteen circuit LEDs are mounted on the faceplate. The status LED shows
the status of the CEPT link, and each of the circuit LEDs shows the status of one BRI circuit.
The BRI circuit LEDs are also used during card initialization to indicate the progress of the
self-test and to indicate that the download is in progress.
