Lights
Power
The Power light shines red when power is first plugged in. Flashes blue when connection is being set up. This
light should be solid blue when the power is on and the device is ready. It will light up when the router is
powered on, and will flash blue as it is booting up, or for a system self-test or firmware upgrade. If the power
light is red, this would indicate a malfunction.
Ethernet
This light should display a solid blue when an Internet connection is established. If it is off, then this would
indicate no connection on Ethernet. It will flash green when data is being transmitted.
Phone 1
The phone light should be GREEN when the ATA is registered and provisioned. It will blink when a connected
phone is being used or an incoming call has been detected. When the phone is not in use the Phone LED will
be solid as long as the ATA is registered. If the Phone LED is not lit, then the ATA has no registration.
