BRI Card
One status LED and fifteen circuit LEDs are mounted on the BRI card
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 (see Table 102).
