Understanding Indicators
Before configuring your VoIP Gateway, take a few minutes to look over this section and familiarize yourself with
the front panel LED indicators depicted below.
♦ Power
This LED is lit when the device is receiving power; otherwise, it is unlit.
♦
Test
This LED will flash quickly when the CPE is either performing a self test or booting up. The LED will
remain lit when the system is ready for a connection with the Gatekeeper; it will remain dark when the
system is ready but can not receive an acknowledgement from the Gatekeeper.
♦ WAN
This LED displays the connection speed, link status, and activity on the 10/100 dual-speed Ethernet
port that is used to connect to your WAN device (usually a router).
10/100M −
This indicator remains unlit when there is no connection, or the port is operating at 10Mbps
through a connection to a 10BASE-T device. It is lit when the port is operating at 100Mbps through a
connection to a dual-speed or 100BASE-TX Fast Ethernet device.
Link/Act − When a good link to a powered-up but idle device is detected on a port, this indicator shines
steadily. When packets are received from the device, the indicator blinks off and on.
♦
LAN
This LED displays the connection speed, link status, and activity on the 10/100 dual-speed Ethernet
port that is used to connect to your LAN.
10/100M − This indicator remains unlit when there is no connection, or the port is operating at 10Mbps
through a connection to a 10BASE-T device. It is lit when the port is operating at 100Mbps through a
connection to a dual-speed or 100BASE-TX Fast Ethernet device.
Link/Act
− When a good link to a powered-up but idle device is detected on a port, this indicator shines
steadily. When packets are received from the device, the indicator blinks off and on.
♦ Phone 1 to 4
Lights when standard phone port is in use
NOTE:
If a powered-up device is connected to a port and the port’s Link/Act status indicator is unlit, the most
probable cause is a cabling or connection problem (for example, wrong cable type or bad contact) or a
device malfunction.
