Connecting to FXS Interfaces

This section describes how to connect the FXS interfaces to FXS equipment such as fax machines, modems, and plain old telephone system (POTS) telephones. FXS cabling can be routed indoors or outdoors, depending on the FXS module used (see FXS Module ).

FXS modules for indoor cabling: The FXS port interface cabling must be routed only indoors and must not exit the building.
Make sure that FXS ports are connected to the appropriate external devices; otherwise, damage to the device may occur.

(French) Avertissements:

FXS module intérieur: Le câblage de l’interface du port FXS doit être acheminé uniquement en intérieur et ne doit pas sortir du bâtiment.
Assurez-vous que les ports FXS sont connectés aux appareils externes appropriés ; autrement, vous risquez d’endommager l’appareil.

The FXS module is a separate orderable item. This section is applicable only if your device is installed with such a module.
