Front Panel LED Definitions
LED Description
Power Indicates presence of power
Boot
After power up, the Boot LED will be on while the MultiVOIP GSM is booting. It lights whenever the
MultiVOIP GSM is booting, saving a configuration or receiving a firmware upgrade.
WAN
LNK. Link/Activity LED. This LED is lit if Ethernet connection has been made. It is off when the link is down
(i.e., when no Ethernet connection exists). While the link is up, this LED will flash off to indicate activity.
SPD. Speed indicator LED: this is lit when link speed is 100MB/s and off when it is 10MB/s.
Channel-Operation LEDs (one set for each channel)
LS
Line Status.
• Continuous “on” state indicates that the channel is connected.
• Flashing states:
• 600 ms on / 600 ms off – searching for network, no SIM card or authentication in progress
• 75 ms on / 3000 ms off – IDLE mode; registered on network but no call in progress
• 75 ms on / 75 ms off / 75 ms on / 3000 ms off – GPRS PDP contexts activated
• Off state. Channel is off (not ready) or in sleep mode.
RI Ring Indicator. This LED will light when an incoming Ring Signal is detected.
Signal Strength
Bars (0-3)
There are three LEDs for each channel. If no LEDs are lit, there is not enough signal strength to maintain the
wireless connection reliably. If at least one LED is lit, there is enough signal to maintain connection with
Low signal strength. If the left two LEDs are lit, a Medium signal strength is present. If all three LEDs are lit,
a High signal strength is present.
