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.
