For on-demand ISDN, lit when there is a call up over the

 

 

respective B channel.

 

 

For permanent circuits, lit when HDLC packets are being

 

 

exchanged between the switch or router and another TE

 

 

end system device (normally another switch or router)

 

 

over the respective B (data) channel.

 

 

 

 

Flashing Amber

For on-demand ISDN, flashing when data is being

 

 

exchanged.

 

 

 

 

Off

For on-demand ISDN, Off when there is no active

 

 

connection or when continuous data exchange is

 

 

occurring.

 

 

For permanent ISDN circuits, Off when no data exchange

 

 

is occurring.
