This module installs as a network module and can hold any pair of mini
modules. Thus, it can be used to add additional FXO, FXS/DID, E&M, T1/E1
or ISDN mini modules to the system. The maximum number of voice mini
modules supported by a iBG3026 system is seven (three mini module slots,
two network modules with two voice mini modules each).
FXO-4M (4-Port Analog FXO Mini Module)
This module provides four analog voice channel ports for connections to Plain
Old Telephone Services (POTS) telephones. The voice channels connect to the
voice subsystem.
