3.19 MGI3 Card (only use in the OfficeServ 100)
The MGI3 card supports the VoIP Gateway, which enables telephone calls through the
Internet. Since the MGI3 card cannot support the H.323 protocol by itself, the MGI3 card
shall always be used together with the MCP1 card.
When mounted with the 500 MGI3 D-board, the MGI3 card can support up to 16 Internet
telephone(VoIP) ports by adding 8 channels of Internet telephone ports. Up to 3 cards
MGI3 shall be installed in the Basic cabinet 3 universal slot.
Push firmly in the middle of both card ejectors to ensure the card is firmly seated into the
back plane connector
The features of the MGI3 card(such as LAN port connection, RS232C connection, Reset
button, and jumper setting) are identical to that of the ITM3 card, except for the front panel
LED feature.
