data is being transferrd between the consumer premise equipment (CPE) and the cable modem.

 

 

OFF - When no devices are connected to either the Ethernet or USB ports.

 

 

Note: With both Ethernet and USB devices connected to the modem at the same time, when data is being

 

 

transferred through only one of the devices (Ethernet or USB), the indicator will illuminate continuously.

 

 

Whenever data is being sent through both data ports (Ethernet and USB) simultaneously, the indicator will

 

 

blink as described above.
