Connecting to FXO Interfaces

The procedure below describes how to connect the FXO port interfaces to telephone exchange analog lines or PBX extensions.

To protect against electrical shock and fire, use a 26 AWG min wire to connect FXO ports to the PSTN.
Make sure that FXO ports are connected to the appropriate external devices; otherwise, damage to the device may occur.
FXO ports are considered as ES2 (Energy Source class 2).

(French) Avertissements:

Pour vous protéger contre l’électrocution et le feu, utilisez un fil de 26 AWG au minimum pour connecter le port FXO au PSTN.
Assurez-vous que le port FXO soit connecté à un appareil externe approprié ; autrement, vous risquez d’endommager l’appareil.
Le port FXO est considéré être un ES2.

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