Because the LED indicators are shared, the LED illuminates (green) when either port is active. For
example, the LED indicator labeled BRI 1 B1 illuminates when either the BRI1 B1 channel is active or
when the FXS port is active. You can determine the activity status on each interface by using the
following commands.
• For activity status on the FXS ports, use the show port summary command.
• For activity status on the BRI ISDN port, use the show isdn status command.
Figure 1-79 shows a close-up view of the LED indicators.
