MIM-16FXS
Introduction
The 16-port loop trunk interface module (MIM-16FXS) serves to access and handle 16 channels of
analog voice signals over data communication networks. The module provides 16 FXS interfaces:

FXS interfaces are analog subscriber line interfaces that provide ordinary analog telephone and fax
access and also can connect AT0 loop trunks of exchanges.
