Introduction
The 8-port voice subscriber circuit and 8-port voice AT0 analog trunk interface module
(MIM-8FXS8FXO) serves to access and handle 16 channels of analog voice signals over data
communication networks. The module provides eight FXS interfaces and eight FXO interfaces:
z
FXS interfaces are analog subscriber line interfaces that provide ordinary analog telephone and fax
access and also can connect AT0 loop trunks of exchanges.
z
FXO interfaces are loop trunk interfaces that provide access of common subscriber lines of
exchanges.
While using MIM-8FXS8FXO, make sure that the device can be connected to IP networks or other
WANs.
