CHAPTER 3. Installing and Replacing Modules
3.3.1.2 MGI Module
The Media Gateway Interface (MGI) module converts voice to data and transfers the data
through the data network. It provides up to 16 channels and uses the voice compression / de-
compression standards G.729, G.723, G.726 and G.711. In addition, the module supports the
fax function (T.38 standard).
The procedure for setting the MGI module switches and mounting optional modules is as
follows:
1) Set the memory backup switch on the MGI module.
2) Align a connector on the MGI module to the connector on the optional module
(MGI2D) and press the optional module firmly downward. Up to four optional mod-
ules can be mounted.
