Hardware Descriptions
If configured as PRI, it contains 30 ISDN channels. Protocol is compatible with Euro-ISDN
PRI. (See also PLL, above.)
Media Gateway Interface (MGI3)
Provides a Voice over Internet Protocol (VoIP) gateway between IP and non-IP parts of the
telephone system, as well as Codec conversion. The main features of the MGI3 card are:
On-board Flash memory and data memory
Echo cancellation function supported
Silence suppression function supported, preventing data transfer on the network for the
brief silent intervals between words during calls
Provides an 8-channel interface (expandable to 16 by the addition of a daughterboard) using
the G.711, G.723 and G.729 Codecs for speech compression and T.38 protocol for fax or IP
communication. It also supports proprietary SPnet IP networking.
MGI3 acts as a universal gateway for generic types of VoIP handsets. A maximum of three
cards can be installed in the KSU.
All power to run the system comes from the power supply. Each power supply is rated ac-
cording to the number of stations it will support. When the MGI3 card is installed, it counts as
eight (8) stations of the PSU rating.
3BSI
Provides interface circuits for up to three base stations for DECT 8000. When the 3BSI card
is installed, it counts as twelve (12) stations of the PSU rating; therefore a maximum of 36
keysets can be connected. Only one card can be installed in the KSU.
