Chapter 1 – Description and Specifications
Introduction
The MultiVOIP GSM provides wireless voice communications over the Internet or an Intranet. By integrating wireless connectivity into your existing data network, you can realize substantial savings on
Front Panel LEDs
LED Types. The MVPGSM has two types of LEDs on the front panel:
(1)general operation LED indicators (for power, booting, and Ethernet functions), and
(2)channel operation LED indicators that describe the voice traffic and performance for each channel.

After power up, the Boot LED will be on briefly while the MultiVOIP GSM is booting. It lights whenever the MultiVOIP GSM is booting, saving a configuration or receiving a firmware upgrade. 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.
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.
Ring Indicator. This LED will light when an incoming Ring Signal is detected.
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.
