BRI WAN Interface Card LEDs
BRI S/T WAN interface cards have three LEDs, shown in Figure 3-12 for WIC-1B-S/T and
Figure 3-13 for the WIC36-1B-S/T, and described in Table 3-1. The B1 and B2 LEDs
indicate call activity on the two ISDN BRI B channels. The OK LED indicates that the
ISDN port has synchronized with the central office switch (the D channel is active).
