About the Standby Button
Press the Standby button (on the front of the Telephony Modem) to disconnect your computer
from the Internet when not in use (Standby mode enabled). Press the button again to reconnect
to the Internet (Standby mode not enabled).
The Standby button has no effect before the modem has registered. The current Standby mode
setting is stored in non-volatile memory. If the Telephony Modem is reset or loses power, it returns
to its previous standby state.
The Standby button will not affect telephone service.
Normal Operation
The following shows Telephony Modem LED patterns during normal operation. The power LED
is always on during normal operation. For LED states when operating from battery backup,
refer to the Installation Guide
.
The
Link
LED only indicates the link status of the Ethernet interface. The USB interface
does not use this LED.
