3.3.17 MGI (MEDIA GATEWAY INTERFACE)
The MGI board provides a variety of Voice over IP (VoIP) services for the OfficeServ 7400. This
card is required for ITP/SMT-i phones, IP networking, IP trunking, SIP trunking and stations or
any application that require VoIP.
MGI has 0 voice channels.
The MGI-D daughterboard must be added to the MGI for voice
communications.
Up to 4 MGI-D daughterboards can be added to an MGI board.
Each daughterboard provides 4 voice channels. One MGI with 4 MGI-Ds installed can
provide a maximum of 16 voice channels.
The MGI can go into the universal slots of any cabinet. Add as many MGIs as needed.
Align the connector of the MGI board to the connector of the optional board (MGI-D) and
press the optional board downward. Up to four optional boards can be mounted per MGI.
NOTE: Always install daughterboards starting from the back of the MGI (position 1). DO
NOT SKIP a position when adding daughtercards. (For example: The first MGI-D goes in
position 1, second MGI-D goes in position 2 and so on, working towards the front of the
card.)
